Lean production system |
1. Production Keiretsu (vertical) |
Part Suppliers - Mftr (Assembler) |
|
|
|
Part Suppliers outstide the (parent) company |
=> "lean" production |
|
|
|
Long-term business relationships with part suppliers |
|
|
JIT (just in time) method |
Minimizing the inventory level, the length of queues, etc. |
|
2. Simple job description |
nice coordination under vague division of labor |
|
|
3. job rotaion |
multiskilling |
|
|
4. OJT |
|
|
|
5. Quality Control (QC) circles |
|
|
|
6. Egalitarianism with respect to: |
holidays, medical benefits, parking, cafeteria, open style office, uniform |
[Corporate hierarchy -- rank and status -- with respect to age and seniority] |
Quality Control (QC) |
Origins of Total Quality Mgmt(TQM) or Total Quality Control (TQC): The idea of total quality (TQ) began with Joseph Juran and Edward Deming, both American academics. |
In the 1930s, Sir Walter Shewhart, a laboratory physicist, created ideas of Statistical Quality Control in America. |
|
|
|
During WW II, Deming and Juran elaborated upon the ideas, which now form the basis of Total (not just statistical) Quality Control, and put forward a sophisticated theory of how to improve production at all levels: |
esp., a theory of how to re-organize human resources so that people, the greatest resource of the firm, use their time to the greatest effect |
|
Deming's main points for TQ |
Create constancy of purpose for improvement of product and service. |
|
|
|
Cease dependence on inspection to achieve quality. |
|
|
|
End the practice of awarding business on the basis of price tag alone. |
|
|
|
Improve constantly and forever every process for planning, production and service. |
|
|
|
Institute training on the job. |
|
|
|
Break down barriers between staff areas. |
=> Ambiguous job boundaries and responsiblity |
|
|
Institute a vigorous program of education and self-improvement for everyone. |
|
|
kaizen: the Jpn term for continous improvement. |
This is the Jpn adaptation of TQ. |
|
|
|
Quality Control (QC) Circles: The whole workforce would meet in groups to discuss how to improve quality |
|
|
|
Suggestion system |
The Jpn company managers perceive the suggestion system not as a way of rooting out trouble-makers, but rather as means of persuading workers to think of ways they could increase productivity, and save time and money. |
|
|
|
This reflects the Jpn view of people as the company's most important resource. |
The theory of TQ is very important to the understanding of Jpn decision-making processes. |
Many of Deming and Juran's ideas were based on a form of collectivity. |
The Deming and Juran ideas were not accepted in America in the late 50s; condemned as being unsuitable. |
SQC had become widely used in Jpn before being taken up inthe West more recently. |
|
|
A positive audience in Japan, a society which traditionally exploited ideas of cooperation based on group-oriented behaviour and consensus. |
The Jpn strong foundation in groupism and vertical egalitarianism is intact (= preseved), and there are few dissenters (= those who differ in opinion). |
|
The Deming and Juran ideas are not directly production-oriented; rather their strongest focus is on the social organization (=human side) of industry. |
It is consistent with the Jpn ideas that the human mgmt of people is an art and that human resources are the most imoportant recource in any complex org. |
|
|
The Deming ideas emphasize the group coupled with egalitarianism and ranking, and the need to have a thoroughly systematic approach. |
The Confucianist-based ranking and hirarchical system in Jpn and the way it is reflected in the language, all provide a systematic holistic org. whereby almost all social roles are prescribed and the structure of the org. is not fluid (unstable). |
This provides a more stable foundation for systematic approach that can more readily implement ideas that need to be worked our for the entire system. |
|
|
SQC links quality information with accountability: the workforce is responsible for its own mistakes. |
This eliminates many inspectors and fixers, greately reducing indirect costs. |
|
The Deming ideas of not using inspectors was linked to the basic underlying decision-making process practised by the Jpn. |
The Jpn had a decision-making process in which problems were minimized through pre-impact extensive evaluation: |
*Deming's wheel: Step1 (Planning and pre-impact extensive evaluation: time-consuming stage) -> 2 (Doing: quick stage) -> 3 Checking (Time for this is to be minimized) -> 4 Correcting and Improving (Time for this is to be minimized) -> 1 |
|
|
To evaluate first extensively makes action as risk-free as possible and involves as many company members as possible in this process, and to empower (=to give official authority) actual operators in decision-making processes in their production sphere. |
|
|
|
Such evaluation seeks feedback from up and down and across the corporation, and only when consensus is reached is action taken. |
