Busyness does not guarantee delivery

A delayed order may reflect a capacity constraint, changeovers, shortages, rework or changing priorities. Select one product family and observe actual processing and waiting across representative shifts and demand conditions.

Investigate where work waits

Persistent queues are clues, not conclusions. Check processing time, equipment condition, material availability and release rules. Distinguish insufficient capability from missing prerequisites and blocked downstream movement.

Run a comparable pilot

Define scope, observation period, measures and ownership. Trial one practical change, such as replenishment timing, preparation before changeover, standard work or stable priorities, while protecting quality and safety.

Track delivery, quality, work in progress and workload together. A faster operation that increases downstream queues may not improve the whole system.

Sustain verified methods

Document the conditions in which the change works and incorporate it into routines and handovers. Keep reviewing the process after the pilot. Improvement benefits should be verified using the organization's own consistent data rather than borrowed percentages.
