Capacity the maximum rate of output of a process or a system. Acquisition of new capacity requires extensive planning, and often involves significant expenditure of resources and time.
Capacity decisions must be made in light of several long-term issues such as the firm’s economies and diseconomies of scale, capacity cushions, timing and sizing strategies, and trade-offs between customer service and capacity utilization.
Planning capacity across the organization
Accounting provide cost information needed to evaluate capacity expansion

Marketing demand forecasts needed to identify capacity gaps.
Operations selection of capacity strategies that can be implemented to effectively meet future demand.
Human Resources hiring and training employees needed to support internal capacity plans. planning long-term capacity
