, 3 Production Planning Strategies
-Chase
-Level
-Stable Workforce
Chase Strategy
Perfectly match demand by varying PRODUCTION and MANPOWER by hiring and firing
Chase Strategy Characteristics
Goal: hit forecast without waste (reduce stock outs and high inventory)
-Workforce & hours need to change to meet forecast
-Need EASILY trained employees
-DOWNSIDE: hiring/firing costs; morale decreases
Level Strategy
Maintain a CONSTANT production/workforce level to buffer against the changes in demand
Level Strategy Characteristics
-EASIEST of the 3 to pursue
-Goal: constant workforce & output production level but fluctuating inventory
Stable Workforce Strategy
Stable workforce working at a constant output rate, allowing variable working hours to buffer against
variation
Stable Workforce Characteristics
-Shortages/Surpluses absorbed by fluctuating inventory levels, order backlogs, and lost sales
-Try to keep inventory as low as possible
-UPSIDE: size of workforce constant, hours fluctuates; limits hiring/firing costs
-DOWNSIDE: Decreased customer service, increased inventory costs; possibility of inventory
becoming obsolete.
