Leveling is fine but what if it is not possible to level? What if your business is not repetitive?,
Limitations of lean production has been stated explicitly.
I have seen similarities with TOC in suggested solutions.
For example, having a resrved seat in schedule is reminding me either capacity buffer or protective capacity.
Another example is to scedule the Final Assembly only, which remainds scheduling constraint only.
I wish TOC had a descent volume in this book to complete the concept.
It is not easy to implement in various industries in a volatile economy.
Unfortunately it is still easy to find a reference book for lean compared to TOC.
Companies are still trying to keep their competitive advantage as closed as possible, hiding from rivals..
