Meeting demand vs. quality control. It has been an issue in recent years and now they're paying the price. They got knocked off balance.
Interesting. I mean, I've studied Toyota's production system in detail, and I still don't get why a company who does this would send thousands of products out the back door with problems.
I mean, you've got seven wastes, an eighth which was added by other companies
Defects - quality niggles.
Overproduction - Producing too many of anything so that you can cover a spike in demand.
Waiting - When one station is finished with a product, and the previous station isn't ready, OR when there's a backlog of products at one station.
Transportation - both in and out of a plant, this should be minimized.
Inventory - Best inventory is NO inventory.
Motion - A worker shouldn't have to move around too much to get his job done.
Extra processing - Rework of defects, activities that don't add value to the product.
Unused talents - Not originally used by Toyota, means that everyone's ideas to improve the line, from shop floor to CEO, are important.
These are the fundamentals of Lean...However, could Toyota be becoming so busy that they've started to forget these things they created?
