Issues include….. NUMBER OF SITES CAPACITY OF EACH SITE LOCATION OF EACH SITE a LONG-TERM CAPACITY CHANGE STRATEGY ALLOCATION OF TASKS TO EACH SITE
Many small sites? NUMBER OF SITES and CAPACITY OF SITES Few larger sites? Supply side dominated? LOCATION OF SITES Demand side dominated? All sites make all products/services? ALLOCATION OF TASKS TO SITES Each site focuses on a few products/ services? Capacity leads demand? LONG-TERM CAPACITY CHANGE STRATEGY Capacity lags demand? Questions: “Who should be involved in these decisions?” “How does the company make this type of decision?” Questions Options
