inventory control system

The issue of JIT is mainly about achieving efficiency in the inventory control system which is part of the firm’s overall working capital management policy. As we have learned in the textbook, working capital management is all about managing Current Assets (CA) and Current Liabilities (CL). Firms with a positive Net Current Assets (CA > CL) is usually regarded as healthy firm. However, to what extent this is true is very much subject to empirical validation.Questions: do we really observe firms’ with JIT in place have a healthy working capital management position? In the case of no, what could be the best plausible explanation? Is there any recent practical example/case that exemplify the issues of JIT and working capital management? What can we learn from such example/case? (hint: search Financial Times).
