INVENTORY & SUPPLY OPERATIONS
Sub-Optimization
Sub-optimization occurs when improving one part of an operation undermines the performance of the wider system. Local metrics can encourage decisions that shift cost or delay elsewhere.
SUB-OPTIMIZATION IN PRACTICE
- Identify the local gainName the metric being improved.
- Trace the effectsReview connected work and service.
- Choose the system outcomeCompare complete alternatives.
Use the agreed units, actual records and approved procedures for your operation.
A WORKED EXAMPLE
Less picking labor. More freight.
A warehouse delays order release to consolidate picking work and saves $100 of labor in a hypothetical period. Missed standard dispatch then creates $250 of additional transport cost. The local saving produces a $150 increase across those two cost items before other effects.
WHAT THIS MEANS FOR YOUR QUOTE
Agree the requirement before comparing quotes
Use the actual shipment, stock and service requirements. Record the billing unit, included work and responsibility for exceptions.
A LITTLE MORE CONTEXT
Questions about Sub-Optimization
Is every local improvement harmful?
No. The issue is an improvement that damages the wider objective.
Can high utilization be sub-optimizing?
Yes. If it creates queues, delays or extra cost elsewhere.
How do teams detect it?
Trace connected effects and compare system measures, not just departmental results.
