b. the lack of work in process inventory creates problems.
c. process problems cause production to shut down immediately.

Lean manufacturing is a type of business model where the focus is on eliminating the wasteful activities from the production area, warehouse or office etc and because of these activities a business is unable to add value to customer and limits supply chain capacity, and so by eliminating these wasteful activities , a business would want to provide same quality of goods with greater efficiency.

Therefore whenever there are process problems in lean environment, it causes production to shut down immediately because of the lack of inventory.
