ABSTRACT

Many industry professionals use metaphors to describe problems plaguing their

companies. One metaphor in use today is silo thinking. Silo thinking describes the lack

of communication between departments in an organization. The interaction between

engineering and manufacturing is deemed as critical to the continuous improvement and

quality of products. Without interaction and communication between functions, ideas are

not transferred to those who can utilize the idea. Continuous improvement efforts are

reliant on these ideas. When departments are not interacting with each other, new ideas

often fall to the wayside, because the people who would be acting on them never hear

them. As manufacturing personnel presents new ideas on how to address quality issues

or how to improve a product, if engineering is not interacting with manufacturing,

chances are not good that the necessary changes will be made.

Chapter I: Introduction

“Continuous improvement means that all functions will be involved, but only if there is

trust between them will improvement be realized” (Williams, Van Der Wiele, Iwaarden, Bertsch

& Dale, 2006, p .1278). With increasing competition from foreign companies, American

industry has been working hard to catch up in quality, cost and cycle times. The implementation

of lean, six sigma, and total quality management (TQM) concepts, has helped American industry

gain ground. These efforts often include continuous improvement programs, also considered in

lean manufacturing as kaizen events. In initial stages, the programs reap results in the form of

cost savings, reduced lead times and improved quality. In many cases, the efforts continue to

grow until they level off and reach a plateau. How can a company break the plateau and how can

employee involvement play a role?

Without interaction and communication between functions, ideas are not transferred to

those who can utilize the idea. Results are the same as before, the organization keeps going on

the same path and the plateau is not broken. If the competition is improving, market share may

be lost due to the lack of improvement. When departments are not interacting with each other,

new ideas often fall to the wayside, because the people who would be acting on them never hear

them. As manufacturing personnel present new ideas on how to address quality issues or how to

improve a product, if engineering is not interacting with manufacturing, chances are not good

that the necessary changes will be made. And if they do, the design changes may not match the

product. When engineering directly interacts with manufacturing, these questions and potential

hurdles can be avoided.

In this research, case studies of the interaction between engineering and manufacturing

were analyzed. The case studies collected come from manufacturing companies who have

Page 7: The Effect of Communication on Continuous improvement and

7

custom equipment in their processes or fabricate custom products for their customer. These

companies have in-house engineering staff that designs or is involved in the design, fabrication,

and selection of the equipment. All of the companies involved display good or bad

communication in the case studies which is affecting either the quality or continuous

improvement efforts in the organizations. The affects are a direct result of the lack of interaction

between engineering and manufacturing.

Statement of the Problem

The lack of interaction between engineering and manufacturing is adversely affecting

organizational performance in product quality and continuous improvement efforts.

Purpose of the Study

The purpose of this study was to analyze issues which can maximize or minimize the

effectiveness of the interaction between engineering and manufacturing personnel, and to

improve on continuous improvement and quality in the organization. The study analyzed case

studies of situations when interaction between engineering and manufacturing caused a problem

or corrected an issue.

Assumptions of the Study

This research assumes that communication is critical to product quality and continuous

improvement. With this assumption, it is assumed that without communication, product quality

will not meet customer standards. The professionals involved in this study have intimate

knowledge of the management processes in their companies. It is also assumed that the

professionals involved have knowledge of the manufacturing practices involved.

Definition of Terms

Nonconformance. A non-fulfillment of specified requirements. Also used as a blanket

term to describe a defect or imperfection.

Silo thinking. A popular expression applied to management systems where the focus is

inward and information is communicated vertically. It is considered the opposite of systems

thinking. Also termed: silo effect, silo mentality, silo virus, and silo syndrome.

Systems thinking. A holistic approach of seeing the system as a whole by

understanding the linkages, interactions and processes between the elements that comprise the

whole system.

Chapter II: Literature Review

The literature review covers the topics of silo thinking, continuous improvement, and

quality. The first part of this chapter looks at silo thinking and the symptoms, definitions and

concepts associated with this business phrase. The second part of this chapter will examine W.

Edwards Deming’s teachings on continuous improvement and quality. Special attention is paid

to communication and its effect on quality, continuous improvement and the functions of an

organization.

Silo Thinking

It is a common illusion that an organization is one big happy family, with information

flowing smoothly throughout. Without an effective information flow, the organization struggles.

“Departments that are unable ’to talk to each other‘, and, in particular, often produce more

frictional stresses and strains than actual work, happens in the best enterprises” (Schutz & Bloch,

2006, p. 31). As a result of the lack of communication and trench warfare between departments,

efficiency and effectiveness suffers. This ailment of business is common and phrased as silo

thinking. The expression silo thinking is used to describe a lack of communication and common

goals between departments in an organization.

This is a metaphor drawn from the large grain silos that one sees throughout the US

Midwest. It is a term of derision that suggests that each department on an organization

chart is a silo and that it stands alone, not interacting with any of the other departmental

silos (Business Process Trends, 2010).

Each silo is designated for a specific grain, or as keyed in this term, a functional

department. Each silo is gradually drained of the grain through a small opening at the bottom.

Many organizations are designed in a similar fashion, with departments and divisions divided.

Page 10: The Effect of Communication on Continuous improvement and

10

Organizations typically are structured into divisions and departments based on

functionality. “Organizational experts build structures and describe processes. And so it goes –

each to his own. The image of a centipede comes to mind. However, unlike this funny little

creature, the many legs of different departments do not always move in the same direction and if

one goes the wrong way, the whole system stumbles” (Schutz & Bloch, 2006, p. 34).

Normal practices of an organization can influence silo thinking and the way departments

interact in many ways.

For example if your budget for next year (and your bonus for a successful performance)

is based on the performance of your department or your function, then you would focus

on making sure your department (and, by extension you), was successful. This could be

to the detriment of the company as a whole. This is what causes silo thinking (Comford,

2010, p. 1).

The Problems of Silo Thinking

So, what is wrong with silo thinking? Often the silos are very efficient within their own

function. In an organizational structure; employees are divided into departments based on a

functional area such as manufacturing or engineering. Each function serves their purpose, and in

many cases interaction is limited to certain people within each department. “The larger the

enterprise and the greater the degree of specialization, the greater the need for co-ordination”

(Schutz & Bloch, 2006, p.32). In a research study conducted by Schutz and Bloch (2006), the

authors describe the dangers of corporate egocentrism in six fronts. The first front is fractures in

one’s own department. This front takes the form of conversations between coworkers, in the

hallway, washroom or at the water cooler. Many times the clash of personalities, egos and the

rumor mill in a department creates fuel for these conversations. These conversations, although

Page 11: The Effect of Communication on Continuous improvement and

11

intended as private conversations, often make their way up in the enterprise. As an organization

establishes annual objectives, each department has the task of creating their own set of goals.

The second front is described as fractures in the value chain. Here, the worlds of

engineering, purchasing and other departments collide. Each area is different in objectives,

education and language. Each of the differences can cause confusion and frustration when

working with the other departments.

The interaction of core functions from product development to sales forms the spine of an

enterprise. If dislocations appear, the organism hovers precariously between life and

death. Only smooth and seamless flow of products from their origins to the market, will

ensure survival. Dangers to corporate health can be found lurking particularly where

technology flows into the company’s marketing sphere (Schutz & Bloch, 2006, p. 33).

The functions of production, logistics and development often collide with the world of

marketing, sales and customer service. If these areas have no will to cooperate, bridges in the

functions will collapse.

The third front falls into the managerial hierarchy of an organization. Fractures in the

managerial staff can run both horizontally and vertically.

What matters most is the behavior of decision makers and how closely they are in touch

with reality. If management surrounds itself with yes-men and sycophantic lackeys, even

a flat hierarchy will provide fertile ground for managerial opportunists. Thus,

management forfeits its function as an integrating force and judge and jury over turf wars

(Schutz & Bloch 2006, p. 33-34).

If managers are not willing to work together, the employees under these managers are not likely

to work together as a cohesive team. Departments and managers of an organization need to work

Page 12: The Effect of Communication on Continuous improvement and

12

together towards the strategic and operational goals set forth by top management. If they do not,

the goals and objectives may not be met.

Support function fractures make up the fourth front. The function of information

technology is used as an example of a support function. The support function provides the

system with information and resources. “Support functions are keen to claim that they are

internal service providers, but they often handle their colleagues like useless petitioners. The

internal service desert flourishes” (Schutz & Bloch, 2006, p.34). Support structures form the

base of an organization. Without them, the organization would crash. If IT gets it wrong,

everything temporarily plunges into the Stone Age.

Divisional fractures form the fifth front. Examples of divisional fractures are that of

divisions which function separately, but may supply one another with goods or services. In some

instances the divisions share customers.

As is indeed appropriate, these business areas also take responsibility for their health, that

is, in terms of cost, result and investment. As in the human body, this system cannot be

completely separated from the rest of the organism. There are interfaces which cause

pain. This becomes particularly clear if the separated elements serve the same clients. If

there is no internal agreement, the market gets the impression that the left hand does not

know what the right hand is doing (Schutz & Bloch, 2006, p. 35).

Finally, the sixth front is titled projectitis, which is a reference to project work.

The committees for planning a company social function, anniversary celebration or the

formation of a plant-purchasing, prove this only too well. The team itself lives, but the

joy of decision-making dies. This applies also to project work. In the right dose,

interdepartmental projects are a good remedy for the silo-virus, because they gather

Page 13: The Effect of Communication on Continuous improvement and

13

employees from all areas and direct them towards a mutual task (Schutz & Bloch, 2006,

p. 35).

Eliminating SiloThinking

If we look at silo thinking as a virus, departments and functions within an organization

are not the carriers of the virus, it is the people in the departments. “Consequently, it is not the

chemistry between departments, but the chemistry between people that creates the bridge across

critical interfaces” (Schutz & Bloch, 2006, p. 35). The structure of an organization and culture

play a role in the development of silo thinking. Ultimately it does come back to individual

behavior. An individual willingness to see the realities of the corporate situation as a whole,

beyond their own influence, will reduce the effects of silo thinking in the organization. Many

influential people in industry have pointed out the symptoms of silo thinking and the ways in

which organizations can eliminate them. Deming’s teachings have been the basis of many

organizational initiatives to improve quality and how an organization functions.

Introducing W. Edwards Deming

W. Edwards Deming was a major player in the rebuilding of industry in Japan after

WWII. Many U.S. industries are trying to catch up to the Japanese competition. Deming

witnessed some of the systemic problems in organizations and describes how organizations can

improve to match the Japanese companies in his teachings. American industry did not follow the

change in philosophy until they began to be passed by the Japanese.

The American Quality Revolution got rolling in the mid-to-late 1980’s in large part

because of the thinking and charismatic leadership of three men: Dr. W. Edwards

Deming, Dr. Joseph Juran, and Dr. Tom Peters. Deming and Juran (and other pioneers

such as Dr. Armand Feigenbaum) gave the movement its brain; Peters gave it its heart by

Page 14: The Effect of Communication on Continuous improvement and

14

inspiring American business leaders to believe that they, too, could improve quality and

that they could excel (Gebhardt &Townsend, 2006, p.1).

Deming’s fourteen points for Management

W. Edwards Deming is considered as a pioneer and guru in quality management. In his

book Out of Crisis, Deming discusses his fourteen points for management.

The 14 points are the basis for transformation of American industry. It will not suffice

merely to solve problems, big or little. Adoption and action on the 14 points are a signal

that the management intend to stay in business and aim to protect investors and jobs

(Deming, 1986, p. 23).

If American industry is really serious about improving the quality of our goods and

services, there must be a change in attitude. Management must lead the way, demonstrating a

long-term commitment to improving in everything from the products to the relationships with

customers and vendors. The Deming philosophy stresses a commitment to never-ending

improvement. In order for an organization to make this commitment there will in many cases

need to be a reallocation of resources away from traditional structuring in addition to the change

in attitude.

If top management does not have a long-term perspective, these resources will not be

allocated in a meaningful way. American companies must concern themselves with the

problems of today and tomorrow. Management must have the view that the company

will be in business in the future and must look towards innovation. Resources must be

made available for training, education, and research in order to improve quality (Gitlow

& Gitlow, 1987, P. 17).

Page 15: The Effect of Communication on Continuous improvement and

15

A long-term focus is deemed as a critical ingredient to never-ending improvement of the

system, including increased management responsibility for an organizations improvement and

competitive position.

Of course, some may still prefer the traditional type of organization, especially because

of the efficiencies created by the division of labor. Certainly someone who is used to

doing something over and over may be better equipped than others to do that job. Yet, if

we push such an idea to the point of dividing those who use their brains from those who

use their hands, we may not only be underutilizing the talents of people but we are

lacking respect for the individual (Suzaki, 1993, P. 29).

Breaking Down Barriers

Of Deming’s fourteen points for management, number nine directly addresses the topic

of silo thinking and the topic of this research. “9. Break down barriers between departments.

People in research, design, sales, and production must work as a team, to foresee problems of

production and in use that may be encountered with the product or service” (Deming, 1986,

p.24). In further explanation of point nine, Deming talks about gaining understanding of what

internal and external customers require.

Everyone in engineering design, purchase of materials, testing materials, and testing

performance of a product has a customer, namely, the man (e.g., a plant manager) that

must try to make, with the material purchased, the thing that was designed. Why not get

acquainted with the customer? Why not spend time in the factory, see the problems, and

hear about them? (Deming, 1986. p. 62).

Typically the response from engineering is that there is no time, the push for production

prevents them from spending time on the manufacturing floor. It is easy for a company to tout

Page 16: The Effect of Communication on Continuous improvement and

16

the slogan ‘do it right the first time’, but actually doing it is a different story because of the

barriers that exist. One of the more common barriers found in any business is the fear of change.

Most people do not like change. It is an intrusion on their comfortable steady-state

environment. They have been accustomed to doing things in certain ways. People prefer

to do things the same way each time because it took some time to learn to do it this way

and they resist having to learn it all over again (Wilson, Dell & Anderson, 1993, p. 119).

With this barrier, the involvement of everyone in the organization is critical. In many

cases training is necessary as change is implemented. Change must be communicated and

understood by those affected. Suppliers and vendors are also an integral part, creating a ripple

effect as quality is demanded from them and then their suppliers and so on.

One roadblock in American industry is that management often believes that the workers

are responsible for all of the trouble. There would be no problems in production or service if

only workers would do their jobs the way they were taught. However, the workers are

handicapped by the system, for which management is ultimately responsible. Management must

also see and believe that the improvement efforts will pay off in the long run. Management and

labor unions have to remove barriers that impede their cooperation. Removing barriers to

communication between all entities is an important aspect of the new philosophy. Training has

to be used as an aid to removing barriers, overcoming communication barriers can also be

covered as a topic in the training.

Supervision in a “Deming company” should stress the extended process. Employees

must understand the importance of communicating with their vendors and customers,

who are frequently other employees in the system; e.g. Engineering’s customer is

Page 17: The Effect of Communication on Continuous improvement and

17

production, or the vendor to the employee on the line is previous employee (Gitlow &

Gitlow, 1987, p. 145).

Supervisors are key people in helping break down barriers in the system; however there is

a standard practice in most businesses and industry that can create a barrier between a supervisor

and their employees. Performance appraisals or annual review and rating systems can cause this

barrier. Whether it is a design engineer or a manufacturing worker, they are rated by

productivity numbers. Changing from an individualized work environment to a team work based

culture in a company is another attitude which can break down barriers in a “Deming philosophy

based company”. “Teamwork is a risky business. He that works to help other people may not

have as much production to show for the annual ratings as he would if he worked alone”

(Deming, 1986, p.64). Management must demonstrate that individual efforts are not as effective

as cooperative ones. Teamwork issues and examples of instances where teamwork can help with

quality and improvement problems will have to be addressed in training sessions. In order to

change to a team based, cooperative work environment, it is highly likely that some restructuring

may have to take place within the organization. Teambuilding and team based performance

appraisals will ultimately begin to open lines of communication.

People in an organization need to talk, trust each other and work cooperatively. In the

never-ending goal of improvement, there needs to be an elimination of jealousy, competition and

‘protection of turf’. “Continuous performance improvement, if it is to be successfully

implemented, involves close cooperative relationships between the many functions involved”

(Williams et.al., 2006, p. 1278). Once again, this begins with management. Management must

verbally communicate instead of memo writing, maintain open offices, be involved in day-to-day

activities and interact with employees. “Communication is as vital to an organization as the

Page 18: The Effect of Communication on Continuous improvement and

18

bloodstream is to the body. When communication is blocked or slowed, it can have disastrous

consequences” (Cochran, 2006, p. 9). Opening lines of communication also involves

confrontation of barriers and resistance. Change can be exciting, it also can create resistance. It

is up to management to communicate change to the organization to support the often difficult

process of change. When change is communicated in a manner of which everyone understands

the need for the change, the participants will be more willing to accept the new concepts.

There are several potential pitfalls when breaking down barriers in an organization.

When moving to a team based workplace, some managers may have a difficult time with giving

up control to teams. It may be viewed as a way to undermine their authority, but the team will

need to have some autonomy to function properly. Denial of the existence of barriers is another

potential pitfall. Some barriers are very much engrained into an organization, and removing

them may seem overwhelming. One potentially large pitfall is the belief that an area or

department is “special”. Perpetuating the idea that an area is unique or special could have been

accepted in the past, supported by management views. These pitfalls must all be addressed as

they arise in the change process. In a truly cooperative work environment, one benefit that can

arise is a return of pride in the work that the employees are conducting.

Deming’s point twelve of the fourteen points addresses the removal of barriers which rob

employees of their pride of workmanship.

Organizations have seriously erred in their treatment of employees. Workers and

managers are regarded as commodities and are treated accordingly. Not enough attention

is paid to people and their problems; management doesn’t want to deal with these issues.

Consequently, employees become disenfranchised, instead of being involved and utilized

to their maximum potential (Gitlow & Gitlow, 1987, p. 173).

Page 19: The Effect of Communication on Continuous improvement and

19

There are a number of things that can cause a loss of pride. If an employee does not

understand the company’s mission and what is expected from them, they will not be able to

identify with the direction of the organization. If pride and loyalty are restored within an

organization, the communication, quality and involvement will improve by an engaged

workforce. Removing the barriers that hurt employees pride or workmanship will also allow an

organization to drop decision making down to its lowest possible level, enabling workers to

determine if a product meets specifications, make corrections and take greater responsibility for

their workmanship. One potential pitfall to this is if the organization fails to follow through on

employees suggestions. Employees can become angered and frustrated by a lack of

responsiveness by the organization when feedback is not answered. In the Deming philosophy,

cooperation between labor and management is deemed as a key item in the push to improvement

in an organization.

The Deming philosophy

The Deming philosophy is exactly that, a philosophy. The philosophy is focused on

quality and never-ending improvement. Without a pursuit of improvement, an organization can

only stay competitive for a while until the competition overtakes them in the market.

A firm operating under the Deming philosophy must be guided by Dr. Deming’s

Fourteen Points for management. The Fourteen Points are the cornerstone of a

managerial philosophy which will lead to cooperative labor-management relations, never-

ending improvement of quality, and all the resulting benefits (Gitlow& Gitlow, 1987, p.

207).

The views of management and labor must be that of a partnership in quality. Breaking

down the barriers and opening communication can cause frustration as the changes are

Page 20: The Effect of Communication on Continuous improvement and

20

implemented. But, with the long-term in mind a company can increase their competitiveness in

the market place. Effects of silo thinking and other ailments within an organization have to be

confronted in order for the benefits of the Deming philosophy to be realized.

Summary

Most managers want an organization to be one big happy family, with information

flowing smoothly throughout. Without an effective information flow, the organization struggles.

An example of how communication and interaction affects an organization would be that of a

wind turbine. The wind turbine stands tall, in an open field, blades slowly turning in the wind.

Interaction between individuals and departments is that wind, keeping the organizations blades

moving around and around. If the wind stops, the blades will lose momentum and stop. This

relates to the literature reviewed in this chapter the subjects of silo thinking, breaking down

barriers and the teachings of Deming play a direct role in the interaction between individuals and

departments. There are many potential solutions, as covered in this chapter and in nearly all of

them communication plays a big role.

Chapter III: Case Study Methodology

The lack of interaction between engineering and manufacturing adversely affects the

continuous improvement efforts of an organization. While not always the focus of an

organization, the interaction between these departments can be at the forefront of the

organization’s performance. Information collected for this research explored this idea. Case

studies were collected from existing information in five organizations to emphasize the good and

bad instances of the interaction. The organizations involved are introduced in this chapter as

well as the case study analysis. This research was reviewed by the Institutional Review Board at

the University of Wisconsin – Stout and was considered Exempt.

Organizations involved

The companies involved are in four different market segments. The first is a

manufacturing company and fabrication shop who designs and manufactures their own products.

A majority of the products are manufactured and assembled in-house, with a small percentage

manufactured by vendors. The second type is an equipment manufacturing company who

designs and installs the product. All of the manufacturing is produced by a sole source supplier.

In the third case, a situation from a generator manufacturing company is presented. The design,

manufacturing and assembly are done with both in-house fabricated and purchased components.

The fourth company is a food manufacturing company which designs the equipment involved in

their processes. The manufacturing and assembly of the equipment is conducted at multiple

vendors. Some assembly is conducted in house by maintenance personnel. The fifth company,

designs processing equipment which is fabricated at supplier facilities. The design is done from

a remote office, removed from the corporate headquarters as well as the suppliers.

Case Study Analysis

This study analyzes five case situations when the interaction between engineering and

manufacturing caused a problem or corrected an issue. The data is based upon public behavior

within an organization and the Institutional Review Board at the University of Wisconsin-Stout

reviewed the protocol and determined it to be exempt. The situation was analyzed based on the

positive or negative outcome. The data utilized comes from existing sources; no names are

associated with the situations presented. General position titles are given in the cases as

reference. Patterns among the five case studies were identified and analyzed themes in the

situations’ failure or success and analyzed based on the topics covered in the literature review.

Page 23: The Effect of Communication on Continuous improvement and

Chapter IV: Results

The purpose of this study was to analyze current issues which can maximize or minimize

the effectiveness of an organization. The study analyzed case studies of situations when

interaction between engineering and manufacturing caused or corrected an issue. Case studies

presented in this chapter come from existing information. The companies involved are

equipment manufacturers, or use customer equipment in their processes. Each of the companies

has engineering staff responsible of creating the manufacturing drawings used to fabricate the

equipment.

Case Study 1

At a well-established manufacturing and fabrication company who designs and builds

their own product, the first case study was obtained. Every other year replacement screening

baskets were manufactured for a key customer. The product had been designed approximately

fifteen years earlier, and the engineer who originally designed the basket had retired five years

earlier. However, the work cell lead man had been building these baskets since its design. The

manufacturing of the basket went flawlessly, until the final inspection was performed.

Inspectors at the final inspection were overwhelmed, and called a Quality Engineer to assist in

the inspection.

Once the engineer started inspecting the basket, he immediately noticed problems. The

weld bead pattern on the basket was only half of what was specified on the drawing and the

engineer wrote a nonconformance report on the spot. Once word got back to the lead man, he

became enraged. The engineer soon became a target of a tirade. “Why would you write this up?

I built those baskets exactly as I have the past fifteen years! What is wrong with you?” the lead

Page 24: The Effect of Communication on Continuous improvement and

24

man exclaimed. Red faced and angry, the lead man stormed off, leaving the engineer in a state

of shock.

After allowing time for everyone to calm down, the engineer went to the lead man

seeking an explanation on how these baskets had been built this way for the past fifteen years

since the manufacturing did not conform to the drawing. By this time an audience had collected

around the baskets, including the shop supervisor. Not wanting to enrage the lead man any

more, the engineer questioned the shop supervisor. “I wrote these baskets up because they are

not built to print. Are the baskets built wrong, or are the drawings wrong?” As the shop

supervisor began to explain, the lead man joined in. “The engineer who designed this was an

idiot! We cannot put that much weld on these, the heat will be too much and warp them out of

shape!” “Did you send this drawing back to design engineering requesting changes?” asked the

engineer. “Yes, many times but the design engineering kept ignoring us.” stated the shop

supervisor. The quality engineer left to call one of the senior design engineers to the shop floor.

Once the situation was explained, the senior design engineer analyzed the baskets and the

drawing. “I would agree that there is too much weld called out on the drawing, and these baskets

look good to me” responded the senior engineer. With the non-compliance signed off, the

baskets were shipped to the customer. The engineer continued to follow up on a nagging

problem resulting from the recent events. “How can we go fifteen years building a product

without having engineering change the drawings to meet the fabrication techniques?” As the

questions were eventually answered by management, it became very apparent that there was a

discrepancy and conflict between manufacturing and engineering.

Case study 1 key points. Case study 1 presents two major issues. First, the engineering

staff had ignored the recommendations and complaints of the fabrication personnel. How can

the company continue to prosper, with engineers who do not listen to the people building the

product? If it was not for the seasoned fabrication personnel, the product would most likely have

been built wrong and rejected by the customer. In this case there is a systemic problem in the

management system. The supervisor chose to ignore the issue, instead of pushing for

resolution. If he could not convince the engineer to make the change, the shop supervisor should

have pushed this issue to a higher level within the organization. Once the issue is at the higher

level, the engineering manager would have to address the issue with the engineer.

Case Study 2

After being acquired by a major corporation company XYZ had most of its

manufacturing outsourced to a fabrication company owned by the same corporation. Five years

later, XYZ was sold to another corporation. At the same time, the fabrication company was spun

off and became independent. Several managers left Company XYZ and went to work for the

fabrication company. This move created animosity between the companies and it fractured

communication lines. The fabrication company continued to build products for company XYZ.

During a visit to the fabrication company, a quality assurance engineer inquired about the

communication between the companies. As the conversation moved to the communication of

engineering errors and changes, the engineer was shocked to find out that many design errors

were being corrected by the fabrication company and not being sent back to XYZ. The engineer

was then shown a stack of design changes and errors from the current production job. This

paperwork was internal documentation reporting design to the fabrication company’s quality

department. After the quality department reviewed them, they were sent to the engineering

Page 26: The Effect of Communication on Continuous improvement and

26

department for design changes. The fabrication company had been utilizing their years of

experience building the machines and had been using their internal engineering staff to make

corrections on their internal fabrication drawings. The changes were never communicated back

to company XYZ.

When the engineer returned to his office, he looked into the engineering change system to

verify his assumption that the corrections that the fabrication company was doing to the drawings

were not being replicated on company XYZ’s side. His fears were found to be correct, company

XYZ was repeating the same design errors on nearly every job, and had been for years. The

engineer spent the next couple weeks working with the design engineering manager to sort out

the proper communication lines for the errors found at the fabrication company. Initially the

efforts were met with a great deal of resistance, and the design staff worried of becoming

overwhelmed with the extra work. But the design engineering manager and the quality

assurance engineer were determined to prevent the repeat errors and improve the design. The

changes that the design engineering manager and quality assurance engineer had been pushing

for soon were bearing fruit, as the fabrication company began calling and emailing the design

staff with issues as drawings as they were discovered.

Case study 2 key points. In case study 2, there are barriers which are preventing the two

companies from communicating the issues and errors. Not only is there a physical barrier in the

distance between the companies, but there also is a mental or emotional barrier. The animosity

between the two organizations is causing communication barriers. The two companies will need

to set aside old differences and work together in order to break down these barriers. Both

barriers can be minimized with open communication. The fabrication company needs to

communicate design issues and errors back to company XYZ. The engineering staff must

Page 27: The Effect of Communication on Continuous improvement and

27

address these issues, to prevent repeating problems, as they have in the past. Once the problems

are addressed, with standardization of the products, the correction will not need made repeatedly.

Case Study 3

Company ABC manufactures generators for residential and industrial markets. Standard

procedure for the company is to test 100% of the generators prior to shipment. The first

production unit of a new model was being tested, only to fail. The engine would not reach full

throttle, it would sputter and die. Test personnel attempted to determine the cause of the issue.

Initial thoughts were that the engine was bad coming from the supplier. The engine supplier was

contacted to assist in the problem solving. The generator was connected to the internet to run

diagnostic software which takes data points from engine sensors to verify engine performance

compared to the suppliers specifications; the supplier deemed the engine to be per specification.

Quality control was contacted to coordinate and lead the problem solving process. The

mechanical engineer for the product line was contacted as well. As the mechanical engineer

worked with the test personnel to trouble shoot the generator, no solution was found. The

engineer had a hunch that the problem was in the controller programming. Responsibility for the

issue was transferred to the controls group.

The controls engineer who took over the problem looked at the programming in the

controller, and was unable to find a problem. At this point the controls engineer pointed his

finger back at the engine supplier. As supplier quality got involved in the issue, it became

apparent that there has been little to no communication between the test personnel, mechanical

engineering and controls engineering. When supplier quality asked the controls engineer if he

had been shown the data from the internet diagnostics, he stated that he had not. The mechanical

engineer who started working through the trouble shooting process had left out that detail when

Page 28: The Effect of Communication on Continuous improvement and

28

he transferred ownership of the issue to the controls group. When the controls group took over,

they never contacted the test personnel to gain a firsthand account of the problem. The issue had

started out as a supplier issue, and then was considered an internal issue, and finally it was being

considered a supplier issue again.

Even more troubling, during the prototype phase, the issue had been noted in the

Research and Development (R&D) lab. However, the issues witnessed at the prototype phase

were never communicated to anyone outside the R&D staff. During the development phase, the

engine supplier had suggested a new program in the engine emission controls. Company ABC

saw no need for this, due to the fact that the same engine was currently being used on other

models, and wanted to save some money by using the current programming thus eliminating

costs for new programming. As the problem solving wrapped up, Company ABC ended up

having to pay for new programming in the engine, as well as changes to their controller

programming. With the change, the generator passed the test and was able to ship, more than a

month late.

Case study 3 key points. Case study 3 has common issues found in large organizations.

A problem is discovered, as they begin to trouble shoot the issue, responsibility is handed from

one person to another and passing the responsibility off to another department. If the mechanical

engineer had called a meeting with the controls engineer, quality and the test lab personnel, the

controls engineer would have had a better understanding of what the symptoms were and what

had already been done to diagnose the issue. From the R&D phase, there was no communication

beyond the specific department. Throughout the process, there was no follow-up or

accountability by the staff seeking resolution to ensure the proper corrective actions were being

taken. The original generator should never have left the R&D lab without resolution. In this

Page 29: The Effect of Communication on Continuous improvement and

29

case, the time and expense it took to solve the issue would have been significantly reduced if a

formal problem solving process was utilized.

Case Study 4

Company CDE has been a dominant food processing company for a number of years.

They have recently experienced a growth spurt, building new facilities and adding capacity. As

they have grown, mechanical and electrical engineers have been added to their staff to design the

equipment that is used in their processes. Most of the equipment in the facilities is customized

for the company’s specific products. In many cases, used equipment is purchased and modified

to fit their needs. As the company grew, and required more office space, the decision was made

to move the mechanical and electrical engineering staff to another facility and away from the

manufacturing plants.

Company CDE acquired a building with office space and a warehouse fifteen miles away

in another town. One day, the mechanical engineering staff contacted a senior process engineer

to go look at a piece of used equipment which could fit their needs on one of the production

lines. The process engineer traveled with a lead maintenance person for the line to analyze the

equipment. Upon inspection, they decided that the equipment would be usable, with some

modifications.

The equipment was purchased and shipped to the processing facility. Once on site, it was

up to the maintenance staff and the process engineer to make it work. With the mechanical and

electrical engineering team miles away, things moved slowly, there were many design issues.

However, the maintenance crew was able to get the equipment running. This was a common

practice for the company when modifying used equipment. This strategy saved the company in

the long run versus purchasing new equipment.

Page 30: The Effect of Communication on Continuous improvement and

30

One problem that the company faced is that the maintenance crew should be working

towards keeping the production lines running, instead of modifying equipment to be placed in

production at a later date. The other problem the company faced due to this strategy is that each

production line had equipment from a different manufacturer. There was very little

standardization between the production lines. The maintenance staff was stellar in keeping the

equipment up and running, however, when the maintenance staff from one production line was

busy, maintenance personnel from another line would help diagnose the problems on the other

line. Frequently, the maintenance personnel would not know how the fix the problem, since the

equipment was different than what they typically worked on.

Case study 4 key points. The engineering department has a hands-off relationship with

manufacturing in case study 4. How can the mechanical and electrical engineers ensure that the

design of new or used equipment will work, when they have not set foot on the production floor

or seen the equipment in person? The biggest question in this case is; do the mechanical and

electrical engineers really understand the processes and practices involved in modifying the

equipment and the equipment’s function on the manufacturing line? Or is it the maintenance

staff which keeps things moving in the right direction? Where should the maintenance staff be

spending their time, working on modifying the equipment or keeping the current production

equipment running? Without the engineering staff directly involved in the design and

modification of equipment, there was no standardization and therefore more training is required

of the maintenance staff and a greater amount of spare parts will have to be inventoried to keep

the equipment running. With standardization in the equipment, there will be less design work

required as new equipment is purchased. There also would be less training required, which

Page 31: The Effect of Communication on Continuous improvement and

31

would make the maintenance staff more versatile between the production lines and not

specialized towards one line.

Case Study 5

Company EFG designs and sells capital equipment. They are owned by a large

corporation who has over the years consolidated the companies in the division. In the process,

the corporation eliminated facilities, reduced manpower and outsourced all of the manufacturing.

With the consolidation, design and project engineers are required to work on multiple product

lines. From their peak in the late 1980’s, company EFG went from selling and installing 60 units

per year to an average of 18 in the 2000’s. The company is still turning a profit with less

numbers, but the profit margins have been continuously slipping. A cost reduction team was

assembled to work towards reducing the cost of the equipment, with the goal of making the

product more cost competitive. The team was cross functional, including members from

accounting, field service, project management, engineering and quality. Initially the group found

success in reducing the cost of the equipment by changing materials.

However, the efforts soon stalled, due to a lack of ideas. To make matters worse, the

engineers were struggling with the feasibility of potential design changes. The potential design

changes worked in the 3D modeling software, but the engineering staff was having trouble

determining if the changes would negatively affect the performance of the equipment. Several

meetings later, after zero progress, a senior design engineer admitted to the group that he had

never been to a customer site to witness an installation or see a finished piece of equipment in

action. He had previously worked on another product line but with the consolidation of

companies he was now designing the equipment for which the company was attempting to

reduce costs. There was a stunned silence in the conference room, as the engineer had been

Page 32: The Effect of Communication on Continuous improvement and

32

checking and creating drawings for the product line for several years. A couple of other

members admitted they were in the same boat, and had never seen the equipment in person.

In the following weeks, several field trips to customer sites were arranged for group

members to see the equipment and talk with the field service personnel who service and install

the equipment. Following the field trips, the group members had more ideas and the cost

reduction team was back on track. The engineering staff was soon overwhelmed with new ideas.

Key service personnel were brought in to aid in the process. As changes were made, the field

service personnel were critical in reporting the performance. Some of the changes were

reversed, as performance suffered. But, the cost reduction efforts continued to see a dramatic

improvement in cost competitiveness. They would not return to the production levels of the past,

but they were gaining more customers as the cost of the equipment dropped.

Case study 5 key points. Case study 5 is another example of an engineering staff with a

disconnect from the manufacturing and installation of products that they designed. They had

never witnessed the equipment operating in a customer’s facility. The cost reduction team was at

a loss for ideas, until they actually saw the equipment in person. Once they saw the equipment

and spoke with the field service employees who install the equipment, new ideas were generated.

If the staff in the cost reduction group had intimate knowledge of the equipment and were in

direct contact with the field service staff, they would not have had this issue.

Case Study Commonalities

In all of the case studies there are a couple questions that beg to be answered. Do the

participants in the case understand the needs of their internal or external customer? If they do

not understand the requirements of their customers, how does an organization ensure that the

Page 33: The Effect of Communication on Continuous improvement and

33

correct decisions are being made? Are the people within the organization acting in the best

interest of their department, themselves or the customer?

“Everyone in engineering design, purchase of materials, testing materials, and testing

performance of a product has a customer, namely, the man (e.g., a plant manager) that

must try to make, with the material purchased, the thing that was designed. Why not get

acquainted with the customer? Why not spend time in the factory, see the problems, and

hear about them” (Deming, 1986. p. 62)?

The second commonality between the case studies brings up the question, where is the

communication between departments? Unfortunately there is no one silver bullet that can

correct all of the issues found in an organization. Communication plays a very large role in

breaking down the barriers within an organization. Education and training is also deemed good

tools in breaking down the barriers of silo thinking. “Poor communication is the biggest obstacle

most people cite as stopping their company from delivering quality. Communication has to be

improved at the interpersonal level as well as at the organizational level” (Merrill, 2009. p.

xxxii).

Chapter V: Discussion

This research touched into the topics of silo thinking and Deming’s teachings in the

literature review. In the case studies presented in chapter 4, there are issues present which are

directly connected to the management techniques, departmental objectives and the topics covered

in the literature review. There also are issues related to interpersonal and organizational

communication. In this chapter, recommendations will be made on steps to prevent and break

down the barriers of silo thinking.

Recommendations

Many organizational mantras urge “keep your eyes on the customer”. However, in many

cases this reality gets lost. Organizations and people in general have a tendency to look inward

and stop focusing on their customer. When an organization loses site of their customer,

competitors will happily take their customers. Maintaining a customer focus requires regular

attention. There are numerous ways to aid in maintaining focus within an organization. Training

is one of the crucial tools in helping employees maintain a customer focus. Many organizations

conduct conferences and training on a regular basis. The focus on the training is to learn the

products, processes and customers’ needs. Involvement in these training sessions will be

strongly encouraged, and it will be open to all of those who wish to attend. Not only is it an

opportunity to learn about the products and customers, but it also is an opportunity to meet other

people within the organization. Training of this sort would need to be maintained on a regular

basis to keep up with industry trends, and can be good refresher training for all professional

employees, such as engineers.

Leadership and culture in the organization must encourage and influence employees to

keep a customer focus. One way to maintain a customer focus is to keep the customer visible

Page 35: The Effect of Communication on Continuous improvement and

35

within the organization. When a customer provides feedback on a recent shipment or project,

this information whether good or bad should be communicated throughout the organization. As

a customer complaint is received, an organization should treat it as an opportunity to correct a

behavior, process or the design which is in question. Customer complaints need to be

communicated throughout the organization as well. In some organizations, warranty and

customer complaint information is processed by key people, but is not communicated back to the

employees who add value to the products. As a warranty claim is received, why not

communicate this back to the employees building the products. Maybe these employees have a

potential fix to the warranty claim, which would otherwise go undiscovered.

As new employees enter an organization, or employees move to other product lines, the

management of an organization needs to allow for time to gain familiarity with the products.

This is especially true with engineering personnel. To ensure the designs will meet fit, form and

function, the engineers must have intimate knowledge of the products and how the customer uses

these products. It is common place for some organizations to require new engineering personnel

to spend their first couple weeks on the manufacturing floor. At the same time, some

organizations sit new engineers at a computer and tell them to design their product. The

organization that has their engineering staff spending time on the manufacturing floor has a

higher potential for success. However, the interaction between engineering and manufacturing

staff should not be limited to new employee training. Even senior engineering staff needs to

spend time on the manufacturing floor and in some cases at customer sites. Understanding the

needs of internal and external customers will influence the decisions made by employees, as

questions arise. Employees are more likely to make the correct decisions when they understand

these details. The rewards will be that of customer satisfaction, higher quality and less mistakes.

Page 36: The Effect of Communication on Continuous improvement and

36

Interaction between departments is critical to an organization. The culture of the

organization has a lot to do with the level of interaction. There are a number of things that an

organization can do to increase or maintain the level of interaction between departments. Cross

functional teams are utilized by many organizations. As organizations plan facility layout,

another method used to increase the interaction and communication between departments would

be that of work groups. If the department representatives for a product line are located at desks

near each other, the amount of interaction should, in theory, increase.

In a case where manufacturing is done at another site or at a supplier, there must be

outlets for communication. In a case where as the supplier or remote site is in another state,

country or across the street, there needs to be communication between the groups. Ideally, there

would be regular meetings between the key contacts of each organization to discuss issues,

complaints or complements. Whether the communication is via phone conference, email or in

person, feedback can in many cases make or break acceptance of an order. Feedback is critical

in a situation such as this, so that the design professionals understand the processes involved in

manufacturing the product.
