Abstract:The design and implementation of an organization's quality management system is influenced by
varying needs, particular objectives, the products provided, the processes employed and the size and structure of
the organization. ISO 9001:2008 specifies requirements for a quality management system where an organizationneeds to demonstrate its ability to consistently provide product that meets customer requirements, and aims to
enhance customer satisfaction through the effective application of the system, including processes for continualimprovement of the system. This paper focused on the methods for assessment of quality objectives at ABC
industry. This is useful for them not just for improving their supply chain performance but for improving their
outsourcing strategies and approach. The quality level is also increased from 3.83 to 4.15. The organization
continually improves the effectiveness of the Quality Management System through the use of quality policy,
quality objectives, analysis of data, corrective and preventive action etc.
Keywords: QMS-Quality Management System, SCM-Supply Chain Management, Customer Satisfaction,
Rejection, Rework
Introduction:
The effective deployment of ISO 9000 quality management system (ISO 9000 QMS) has been widely
recognized in recent years as a means of building sustainable competitive advantage and thereby enhancing firm
performance. ISO 9000 standards are internationally recognized and designed to demonstrate that the supplying
organization has achieved a basic level of quality by the formalization and documentation of its quality
management system.[1] For this study a number of recent publications related to the effects of ISO 9000 quality
management system were reviewed. Australian manufacturing companies found that certification is likely to
lead to both actual and perceived quality improvements, as well as overall improvements in organizational
performance. [2] It is proposed that ISO 9000 certified companies in the US industry expect their quality
systems will lead to improving product design, process design, product quality, public image and supplier
relations. [3] Despite the clear definitions and objectives of ISO 9000 QMS and its widespread international
acceptance, there is considerable confusion and frustration surrounding the role and business value of ISO 9000certification. Although the number offirms that want to implement ISO 9000 QMS is increasing day by day,
many of them increasingly started questioning the link between ISO 9000 QMS and firm performance. [4]

Nearly 900,000 organizations in 170 countries have adopted the ISO 9001 Quality Management System
standard, a remarkable figure given the lack of rigorous evidence regarding how the standard actually affects
organizational practices and performance. Implementing a quality management system that conforms to ISO
9001 requires companies to document operating procedures, training, internal auditing, and corrective action
procedures. It also requires companies to implement procedures to improve existing procedures. [5]
The literature has identified several controversies in defining the nature of relationship between ISO9000 QMS, manufacturing parameters, competitive priorities and firm performance. The first research question
deals with the performance improvement of firms as a result of ISO 9000 QMS certification. The second
research question deals with how the performance is improved. In order to examine the research questions a
research framework was developed. [4]
The Research framework (fig.1) shows that ISO 9000 is an initiatory Phase of affecting firm
performance. Model suggests that the relationship of ISO 9000 QMS, manufacturing parameters and
competitive priorities is linked to firm performance through customer satisfaction. The exploitation of ISO 9000
QMS standards is expected to generate new manufacturing capabilities that influence competitive priorities.
This situation increases customer satisfaction that leads to firm performance improvement.
Fig.1. Research Framework
Based on the research framework, the study firstly will focus on the first research question that deals with the
performance improvement offirms as a result of ISO 9000 certification.Therefore the study will examine if there
is a significant difference between the ISO 9000 certified and non-certified firms in relation to the firm
performance. Secondly, the benefits of ISO 9000 QMS on manufacturing parameters will be investigated [4].Case Study Implemented at ABC Industry
Brief Introduction of ABC Industry:
ABC has more than 35 years experience of producing web offset and sheet fed offset presses. Over the
years, ABC has emerged as a thriving, nimble, printing machinery enterprise, due to its ability to transform itself
rapidly to meet the challenges of a highly competitive global economy and its commitment to become a supplier
of choice by delighting customers with services and products. Constant modernization and introduction of state-
of-the-art technology at ABC has enabled it to stay ahead in the industry and successfully surpass all

phase of their business reflects in the quality of their products.
In its relentless efforts to meet and exceed the needs and demands of its customers ABC has made rapid
progress in the international market. Leading publishers from South America, Europe, Middle East & Asia have
all invested in their presses. Their customers count on them to give them a product of superior quality at the
lowest cost. Their technical expertise and unrelenting thrust towards continuous quality improvement are theprincipal strengths of ABC. Product of the company is printing machineries, having huge structures. Follows job
order or build to order production, Less accessibility to metropolitan cities, location of vendors at various parts
of the state, Components required for assembly are very costly, manufactured through vendor, abide with
customer specifications, Follow to keep minimum inventory level at the industry level, Relies on the vendor
delivery for the particular item, Fail in commitment given to customer, moreover it sometimes also cause to
loose their order.
Quality Objectives of the ABC Industry:
1. Total Customer Satisfaction.
2. To Ensure Effective Supply Chain Management.3. To Establish Proper Value Stream Across the Organization.
4. To Enhance Human Resource Utilization by Implementing Result Oriented HR Practices.
5. To Evolve as Responsible Corporate Sector, Nurturing Human Values and Concern for Society and the
Environment.
At ABC industry monitoring, measurement, analysis and improvement in processes are carried out in
order to:
1. Demonstrate conformity of the product.
2. Ensure conformity of the quality management system.
3. Continually improve the effectiveness of the quality management system.
In this paper first two Quality Objectives of the Organization are studied, also the product rejections/reworks are
studied with reference to measurement, analysis and improvement.
Part A:
1. Monitoring and measurement of Customer Satisfaction Index:
As one of the measurements of the performance of the quality management system, the organization
monitors information relating to customer perception as to whether the organization has met customerrequirements. Table 01 shows method for obtaining Customer Satisfaction Index for the Period (01/12/08 to
31/12/08).

Due to these corrective actions of measurement, it is found that Customer Satisfaction Index is increased in the
subsequent years i.e. above 80%.
2. Ensure Effective Supply Chain Management.Supply Chain Management is a set of approaches utilized to efficiently integrate suppliers,
manufacturers and stores, so that product is produced and distributed at the right quantities, to the right locationsand at the right time in order to reduce cost and satisfying the requirements. SCM is the processes from initialraw materials to the ultimate consumption of the finished product, linking across supplier-user companies.
2.1Supplier evaluation and selection method:While selecting supplier various criteria have to be considered in the decision making process.
Preference for a given supplier is generally assumed to be depends on an assessment, case-by-case, of the
quality, price, delivery & service he can provide. The relative importance of these selection criteria has been
estimated in various procurement situations. The selection of right source of supply is an important aspect in
materials management. The vendor is to be examined with respect to his capability and competency to supplyright quality of material at right time and at a competitive price.
Suppliers Performance Assessment is done on the following basis:-
1. On the basis of delivery time.
2. On the basis of Quality
3. On the basis of cost/price.
2.2 Supplier Gradation on the basis of delivery time:
The performance on the above criteria is evaluated against the purchase order during the period from
01/04/2008 to 30/06/2008.After processing purchase order as per work instructions & duly approved is sent to
supplier for manufacturing as per quality norms agreed and mentioned in purchase order. The analysis on the
basis of actual delivery against scheduled delivery is made once in three month and feed back is given to
supplier to made once in three month and feed back in given to supplier to improve upon.
The following table shows the delivery status of goods. If the material received as per the chart given in
the table it is treated as material supplied in time.
Table 02 Delivery Status of Goods
Area Difference Between S.D. To Actual Delivery

2.3 Supplier Gradation on the basis of Quality:
Supplier Quality assessment for the quarter April-2008 to June -2008
Procedure:-
Quality rating (Qr) for a lot is to calculate by following formula
Qr =Q1 +(X*Q2)/Q*100
Where,
Q =Total Qty.Supplied.
Q1=Qty.Accepted.
Q2=Qty. Accepted with deviation.
X =Demerit factor when material is accepted with deviation.
If Major deviation Demerit factor=0.5
Minor deviation Demerit factor=0.8Major means for critical components which requires due attention while production.
Minor means requires less or no attention during further processing.
Suppliers are categorized once in three months on their current performance basis.
A- Performance having acceptance above 90%
B- Performance having acceptance between 81 to 90%C- Performance having acceptance between 61 to 80%
D- Performance having acceptance below 60%
All suppliers will be informed about there present Performance also suppliers in categories C and D
will be informed, to improve there present Performance. The Performance of suppliers in C and D Class in next
months shall be assessed and informed.

Example of Supplier -4Total Inspected Quantity = 468
Total Accepted Quantity = 266
Total Re-work Quantity = 159
Total Rejected Quantity = 43Quality Rating = 266+ (0.6*159)/468=77.22%
Hence Gradation of Supplier -4 is in C Class.
2.4 Guide-Lines for Actions to Be Taken On D Class Suppliers:
If the suppliers rating observed in class D for quarterly analysis report, the reasons for poor quality are
to be studied by Materials Department along with Quality Assurance dept.The feed back regarding poor quality
supply, is to be discussed OR communicated to the supplier by Quality Assurance dept. Necessary technical
guidance to be provided to the supplier for improvement in the supply by Materials Department or Quality
Assurance dept.Suppliers performances for three-quarters are to be analyzed and if the suppliers rating observed
in D class then again, that supplier is to be treated as Temporary Supplier and it is deleted from the list of
Approved Suppliers. Such suppliers to follow the same route to qualify for the list of Approved Suppliers.
During the detailed study /enquiry /observations, if the supplier is found observing wrong business practices, as
detailed below, then the supplier is declared as a Black-listed Supplier.
1. Supply of Non-genuine brand/make materials.
2. Submission of false inspection reports.
3. Supply of our parts to others to others like competitors, customers.
4. Disobey of secrecy agreement.
5. Unethical practices in commercial dealings.
Such incidences are to be recorded by Quality Assurance dept.and brought to the notice of Materials
Department and the supplier. The list of Black-listed Suppliers is to be finalized jointly by HOD PUR, /HOD
VRD & HOD QA. Materials Dept. PUR/VRD will not procure any material from the Black-listed Suppliers.
2.5 Supplier gradation on the basis of cost /price:
The following table shows supplier gradations on the cost basis. The Supplier which gives products at
minimum cost will be considered as the best supplier, but at the same time it is also necessary to see that
whether the supplier is capable to deliver the same at the right time, at right quality and in right quantity or not.

Results and Discussions:
With the globalization of the world economy, the delivery and environmental factors that influence a
companys global strategies and approach. The case study implemented at ABC industry, is useful for them not
just for improving their outsourcing strategies and approach but also high customer satisfaction, very low
inventory level and increase in profit.
From the reports of rework and rejection it is observed that there is considerable reduction in the
rework and rejection. Major issues are discussed in the management review committee meeting and the
corrective and preventive actions are taken to eliminate the cause of non-conformities in order to prevent
recurrence. The quality level is also increased from 3.83 to 4.15. From this the effectiveness of quality
management system is observed.
