Process Control at Compaq Computer Corp. (A): Understanding the Build-to-Order Decision

Compaq Computer Corp., like many manufacturers, faces operational choices that strongly influence the cost of capital engaged in inventory, customer response time, and potential product obsolescence. This case describes some key operations strategy choices regarding two types of inventory: operation inventory (e.g., flow) and tactical inventory (e.g., finished goods). Tradeoffs in inventory management and customer response time are explored in the context of a firm that is changing from a push manufacturing to a customer-oriented pull system. Optional computer simulations (B case) visually display the dynamics of push and pull systems, kanban squares, and their effect on inventory requirements and customer response times. The simulations require the ProModel simulation software tool (not included, to be purchased separately) and computer simulation model files (available from the authors' website: http://faculty.insead.edu/stephen-chick/simulations).
