This week we learned about
Lean Systems. Our
textbook defines lean systems as "operations systems that maximize the value added by each of a company's activities by paring unnecessary resources and delays from them."
Lean systems typically have the following characteristics:
- Pull Method of Work Flow
- Consistent Quality at the Source
- Small Lot Sizes
- Uniform Workstation Loads
- Standardized Components and Work Methods
- Close Supplier Ties
- Flexible Workforce
- Line Flows
- Automation,
- Five S (5S) Practices
- Preventive Maintenance
One of the things I found interesting about this chapter were the new Japanese terms I learned that the Japanese use to describe their application of lean systems principles. One of the words I liked was "poka-yoke." Poke-yoke are defined as mistake-proofing methods aimed at designing fail-safe systems that minimize human error. A company could use the poke-yoke method by making different parts of the modular product in such a way that allows them to be assembled in only one way--the correct way. I think that is such a good idea. If I'm ever in charge of designing a modular product, I'll remember and try to apply this poke-yoke method.
The Kanban system was introduced in this chapter too. Kanban is a Japanese word meaning "card" or "visable record." I've heard the term mentioned in my cost accounting class before, now I understand what it is better and that it's a word with Japanese origins. I'm pretty sure we use a type of Kanban in our office processes of preparing tax returns.
