1. The basic way of thinking that is supporting KAIZEN (1)

・ KAIZEN is an activity which improves something to better result. The activity includes not only small improvement without significant investment, but also the major reforms/restructuring projects.

・ KAIZEN is a source of competitiveness. The company which maintains the competitiveness for long time has the characteristics that the employees continue KAIZEN activity. The implementation of continuous and organizational KAIZEN is a key of the prosperity in the company.

・ KAIZEN methods vary depending on the conditions of the company which practice KAIZEN. a. The scale of the company b. The field of industry and the kind of products produced in the company c. The activity in whole the company or in the limited department d. The limited subjects applied or everything e. The company has already experienced KAIZEN or not. The level of the results has been high or not.

①What is KAIZEN

1. The basic way of thinking that is supporting KAIZEN (2)

②How to promote KAIZEN activity systematically 　　

・ Requirements for the systematic promotion a. Knowledge and capability to practice KAIZEN. b. KAIZEN in all the departments. c. Establishment of the groundwork for KAIZEN.

・ Subjects of KAIZEN should be in line with the direction set by the management　 The policy of top management is detailed to each section. The objectives are selected for KAIZEN activity. 　

・ Establishment of the system for the actions　 The organization of promotion, the rules, the commendation system, etc. for KAIZEN activity are established.

1. The basic way of thinking that is supporting KAIZEN (3)

・ Groundwork for KAIZEN　 It is necessary that importance of KAIZEN, fundamental capability for the improvement, importance of the standardization are understood by all members of KAIZEN activity.

　 The system is established to promote KAIZEN activity.

・ Continuous education & training　 The basic knowledge is required to utilize or promote KAIZEN activity and it is necessary to the system for the organizational education.

Fig. 1-2 The groundwork for KAIZEN

It is necessary to make the system for organizational education or training in addition to individual capability in order to advance KAIZEN activity.

③P-D-C-A and continuous KAIZEN

・　 KAIZEN is to rotate the P-D-C-A cycle　 The basis of KAIZEN is a cycle to take necessary actions after the observation of actual conditions.

Fig. 1-3 The fundamental QC principle of management : P-D-C-A and KAIZEN

・ Continuous KAIZEN by high level of P The target of actions is gradually made high due to implementation of P-D-C-A cycle and the output level of KAIZEN can finally becomes high.

2. Focus of improvement under the KAIZEN

Points for the actions Examples of the actions Expected results

Unreasonable volume, quantity of things, space, time “MURI” in Japanese

Improvements from too much or too little volume of things, areas, volume & quantity to proper situation

Removal of unsafe part, better quality

Useless materials, works, spaces, time, volume & quantity “MUDA” in Japanese

Reductions of excess work, time, transportation, information, documents, processes, facilities, energy, etc.

Reduction of cost & areas for inventory, better productivity

Uneven things, time, volume & quantity “MURA” in Japanese

Improvement for working standard and even things, materials with equality, etc.

Revision of working standard, even level of quality and productivity

Sugges- tionSystem forImprove- ment

This method was started in USA as “Suggestion System”. “Suggestion System for Improvement” was started in Japan since around 1950. This system was first put into practice mainly in a manufacturing section, and gradually expanded into office work sections. It was widely developed as the type of improvement by all the workers in the workplace in stead of USA type improvements which are attached importance to an individual idea.

5SActivity

5S is one of KAIZEN activities by using 5 processes, namely, SEIRI, SEITON, SEISO, SEIKETSU and SHITSUKE in workplace. For the first, it was applied to whole the factory by means of improvements for productivity, delivery, quality and safety, and it was gradually extended in office work sections to get same effects. The 5 Japanese words composed of the actions spread out worldwide. They mean typically rearrangement, tidiness, cleaning, cleanliness and discipline.

TQM

TotalQualityManage- ment

Targets for quality improvement are decided and the actions are set to realize the targets company-wide. The typical actions are: communication of targets to workplace concerned, education & training to supervisors, to extend consciousness of quality & cost, manufacturing with quality control, cooperation with all sections concerned, to complete the quality targets together with suppliers and to keep high quality when changing to new model smoothly.

QCC

QualityControlCircle

QCC is an organization to take actions for improving production processes and quality etc. by workers in each workplace. That is so-called “Small group activity” organized as “informal party. To study quality improvements, “QC 7 tools” are used. The results of the activity are mainly quality and productivity improvements, but lately, many other sections are aiming at improvements of any work. A part of the activities is similar to “Suggestion system for improvement”.

TPM

TotalProduc- tiveMainte- nance

Preventive maintenance “PM” was introduced in USA in 1950s for the first. Maintenance activity for facilities was introduced by changes from Back maintenance “BM” to → “PM” → Complete maintenance (CM) in Japan. Then TPM was introduced in Japan as an independent activity by “Small group activity” in workplace in 1970s. The results expected good effects were expanded in controls of productivity, quality, cost, delivery, safety and human resources. A part of this activity is similar to 5S activity.

JIT

Just In Time(Kanban system)

JIT means a way of thinking that necessary quantity of a necessary model should be made in necessary period of time. In order to reduce the inventory of the products in process as possible, mixed different models are sent on the production line one model by one model. The lead time of total process is reduced as possible so that the company can get the competitiveness in the market. “Kanban (signboard) system” is a definite method of JIT.

6. Knowledge and tools supporting KAIZEN activity (1)

QCQuality　 Control

The QC tools are concretely used to utilize the statistical method for analysis or for removing of scattering product quality, and also used for the incoming inspection of raw materials from suppliers. QCC activity is usually supported by QC 7 tools. To make the process standard for production of which quality is important, the QC process chart is needed.

I EIndustrial Engineering

The IE Analysis method is practically used for the improvement of workplace. For example, the process analysis is used as a tool to implement an order of SEITON(tidiness) of 5S. In short, IE, QC, VA/VE is used to find problems and also used as the fundamental skills for the improvement.

VA/VEValue AnalysisValue Engineering

The purpose is to make the value maximum when the product value is defined as Value = Function/Cost. To realize the maximum value, design change, revision of specification, process and layout improvement, and improvement required to suppliers. VA Is a skill for the stage of manufacturing and VE is for the stage of engineering.

Standardiz- ation

This is an action to make standards of software and hardware and helps on everything in the management. When a working standard is revised , then, the improved process is applied to other process with good results, it becomes a new standard. In case that various kinds of parts are unified as a standard to reduce to a variety, the numbers of tools used can be reduced, the stock area of parts is reduced and the cost can be reduced because of the mass production.

6. Knowledge and tools supporting KAIZEN activity (2)

Management by Objectives　

Various skills are included in the management by objectives. For example. Top management or manager can easily give direction by looking at so-called the visible control board shown the progress of project or actual operation.

Cost Management

After the product specification was revised or the working process was changed by KAIZEN, the results should be numerically clear by the cost accounting.

ITInformation Technology

IT is helpful on the improvement of management efficiency and additional values to many matters. It is necessary to use carefully and not to put confidence in IT.

Safety Management

The basic knowledge of safety operations, standard inspection of safety, control and arrangements for safety wears, etc. are useful on KAIZEN.

Education and Training 　

It is necessary that employees attend the small group activity and that they learn the basic knowledge about the working process, safety, discipline, etc. , and that manager gives helpful comments to KAIZEN activity.

Documenta- tion

To utilize commonly as information source, all sorts of standard, know-how, data, working instruction, etc. in writing are accumulated and stored. This is the source for the development and the property of the company.

7. Common features of workplace in the company of bad management

・ There are common symptoms for the company of bad management. 　・ Employees do not greet each other, they are also cheerless, the attendance ratio is always low, defects of products are increasing, tools are scattered around workplace and materials are piled disorderly in the company.

・ Troubles caused by products and problems of product delivery remain unchanged, human relations become bad, and KAIZEN activity is not practiced.
