Exam Operations-Management Topic 1 Question 56 Discussion

Effective capacityrepresents themaximum output a system can realistically achieve under normal operating conditions. It is alwayslower than design capacity, which assumes ideal, uninterrupted conditions.
StatementAis correct because effective capacity accounts for:
* Scheduled maintenance
* Breaks and shift changes
* Setup times
* Normal inefficiencies
StatementBis also correct because effective capacity is considered astable, ongoing measureused for operational planning and performance evaluation. It reflects how a system is designed to operate sustainably over time, not temporarily.
StatementCis incorrect because effective capacity is not a short-term or temporary measure; it is used consistently for planning, scheduling, and forecasting.
StatementDis incorrect because effective capacity does not define aminimumoutput level-it defines a realistic maximumunder expected conditions.
In Operations Management, effective capacity is essential for:
* Capacity utilization calculations
* Aggregate planning
* Location and facility decisions
* Bottleneck analysis
By distinguishing between design and effective capacity, managers avoid unrealistic expectations and plan resources more accurately, reducing congestion, overtime, and quality problems.
