Calculating Utilisation: The standard formula is: . This allows managers to quantify efficiency and set targets.
Increasing Utilisation: Strategies include aggressive marketing to boost demand, diversifying the product range to fill seasonal gaps, or sub-contracting the spare capacity to other firms (acting as an outsourcer).
Rationalisation: If a business consistently operates with high spare capacity, it may choose to 'downsize' by closing under-utilised factories or selling off idle machinery to reduce the total maximum capacity and lower fixed costs.
Managing Over-capacity: To handle demand exceeding 100%, firms may use temporary staff, implement overtime, or outsource specific components to external partners to maintain delivery schedules.
| Feature | Under-utilisation (Spare) | Over-utilisation (Full) |
|---|---|---|
| Unit Costs | Higher (Fixed costs spread thin) | Lower (Maximum efficiency) |
| Flexibility | High (Can accept new orders) | Low (No room for growth) |
| Maintenance | Easy to schedule downtime | Difficult; risk of breakdowns |
| Staff Morale | Low (Fear of redundancy) | Low (Stress and burnout) |
Formula Manipulation: Be prepared to rearrange the capacity formula. If given the utilisation percentage and actual output, you must be able to calculate the maximum capacity: .
The 'Unit Cost' Argument: In any essay regarding capacity, always link the level of utilisation to the impact on unit costs and how this affects the firm's ability to compete on price.
Qualitative Factors: Don't just focus on the numbers. Consider the impact on brand reputation (quality issues at full capacity) and employee motivation (job security vs. stress).
Outsourcing Risks: When discussing outsourcing, always balance the cost benefits against the risks of losing control over quality and the potential for intellectual property theft.
