Capacity
Also known as: operational capacity, production capacity, maximum output
Definition
The maximum amount of work or output that a business can produce in a given timeframe with its current resources.
The maximum rate of production or service delivery that an organization, department, or system can sustain under standard operating conditions.
Why it matters
Selling more than your business can deliver leads to poor quality, long delays, and customer churn. Understanding your capacity allows you to match sales demand with delivery capability. If you want to scale revenue, you must first calculate and increase your operational capacity.
Improvement tips
- Measure your actual capacity based on historical performance rather than theoretical maximums.
- Identify the single constraint that limits your overall capacity and focus improvements there.
- Build in a buffer of ten to fifteen percent capacity to handle unexpected demand spikes without failure.
Common mistakes
- Assuming you can run at one hundred percent capacity indefinitely, which leads to employee burnout and equipment breakdown.
- Investing in extra capacity before identifying if there is sufficient customer demand to fill it.
- Failing to adjust capacity calculations for employee vacation, training, or machine downtime.
