Direct answer
Measure OEE at the constraint and address the largest loss category first. Capital is justified once the loss structure shows a physical ceiling rather than an operating one.
What this domain covers
- Nameplate capacity far exceeds actual output
- Downtime causes are unrecorded or anecdotal
- Changeovers are long and variable
- Quality losses are treated as normal yield
- Capacity requests are made without OEE evidence
Solution approaches
OEE and loss analysis
Structured measurement of availability, performance and quality losses.
Changeover reduction
SMED methodology converting internal to external setup.
Constraint management
Protecting and exploiting the bottleneck before elevating it with capital.
Targeted debottlenecking
Small capital at the constraint instead of full line replacement.
Engineering and project considerations
- Data quality first: unreliable downtime data produces confident wrong decisions
- Operating improvements are cheaper but require sustained management attention
- Some ceilings are genuinely physical — recognise them and invest
- Improvements must be locked in with standards or they decay
- Productivity gains change the constraint location; re-measure after each change
What to prepare before engaging engineering companies
- Downtime and loss data for at least 8 weeks
- Changeover time records
- Quality loss data by cause
- Demand forecast to size any resulting capital case
What to measure
Frequently asked questions
How much capacity is typically hidden?
In plants without structured OEE management, single-digit to low double-digit percentage gains are commonly available before capital is required. Evidence, not assumption, should decide.
