OLD WAYS
Where hidden capacity usually lives
Waiting for material, tools, instructions or upstream work
Excess walking caused by layout and presentation
Unbalanced work content between adjacent stations
Micro-stoppages that never reach a downtime log
Rework loops and repeated quality checks
Handoffs where work sits between people and machines
Each event looks small. Across a shift and an entire line, it becomes capacity.
Start with the business constraint
Choose a process where backlog, overtime or missed plan creates a clear cost. Avoid instrumenting everything at once.
THE SOLUTION
A practical method for finding capacity
Build a complete timeline of productive steps, waiting, walking, interruption, rework and handoff time.
Separate symptoms from causes. A long cycle may reflect material, layout, quality or workload.
Rank repeated loss by its impact on throughput.
Change one condition and compare the same process before and after.
The ISO 22400 framework provides consistent manufacturing KPI definitions. Manual operations need that discipline plus the context that explains human-led work.
Recover capacity without turning people into metrics
Measure the workstation, operation, line and process condition—not a leaderboard of individuals. Operators should help interpret the data; process evidence gives their knowledge weight.
RESULTS
Capacity before capital
New automation or headcount may be the right decision. Both decisions are stronger after the current process is visible. Measure first, recover what the factory already has and invest where evidence shows a remaining constraint.
Frequently asked questions
What is hidden capacity?
It is usable production time currently consumed by waiting, walking, rework, imbalance and interruptions.
Which metric should come first?
Start with the metric tied to the business constraint, then add the events needed to explain it.
Can existing cameras help?
Yes. Privacy-conscious computer vision can convert activity into process events without wearables.
