Factory development trials during peak season
Schedule trials against the factory's actual workload, with protected equipment time and named technical staff. Keep trial materials and settings separate from routine orders. Defer production changes if the trial cannot represent the intended process. For coordination with staff in China, contact Cambridge China Bridge.
Check the factory's own busy period
Ask the production planner which orders compete for the equipment, tooling and people your trial needs. Check the actual proposed production route, including subcontracted operations. The factory's busy period may differ from your UK selling season; a sales contact's promised sample date does not confirm an available trial slot.
Separate exploratory work from a trial intended to support production approval. Drawing reviews and bench experiments can continue while line access is restricted, but record what they leave unproven. Use the existing new product introduction guide for approval gates; this guide addresses whether the factory can resource the trial.
Separate trials from routine production
Give the trial its own work instruction, material identification and holding area. Mark trial pieces, rejected pieces and retained samples so they cannot enter routine orders accidentally. Record temporary settings and agree who restores and checks the approved setup before routine production resumes.
Separation need not mean a different production line. A protected slot on the intended line can preserve representative conditions while keeping trial output controlled. If a sample room or spare machine is used instead, list the differences and restrict conclusions to what that setup demonstrated.
Confirm the technical people can attend
Name the process engineer, tooling specialist, quality reviewer and production supervisor needed for the work. Confirm their attendance during setup, the trial and the results review. Ask about competing breakdown cover, travel and shift duties; being employed at the site does not mean someone is available for your trial.
Agree a deputy only where that person understands the process and can make the required decisions. If essential expertise is missing, hold the affected operation rather than let sales staff interpret technical results. Put attendance confirmation and the route for resolving problems in the trial booking.
Protect capacity beyond the machine slot
Ask the production planner to reserve setup, running, measurement, cleanup and restoration time, alongside materials, operators and test equipment. Include access to any shared tooling or subcontracted process. The factory production capacity guide helps assess broader capacity claims; your trial still needs a specific booking.
Record who can move the booking, what triggers notification and how a replacement slot is agreed. Reconfirm readiness before sending staff or releasing trial materials. If an urgent routine order displaces the trial, update the plan explicitly instead of squeezing the work into gaps that remove observation or testing.

Defer changes when the trial cannot prove them
Before starting, compare the booked conditions with intended production: materials, tooling, machine, settings, operator competence, process sequence and testing. Record interruptions, substitutions and special assistance. Inspect output across the run and distinguish pieces made normally from those rescued by hand. A successful piece does not establish repeatability.
If missing staff, rushed setup or an alternative process prevents representative evidence, keep the change pending and book a suitable trial. Continue the existing approved process only where it remains acceptable; contain affected work if the change addresses an unresolved fault. Record what must be demonstrated before approval. When qualifying an alternative factory, use the supplier qualification guide alongside this scheduling plan.
Frequently asked questions
Can a factory run development trials in peak season?
Yes, if the intended equipment, materials, operators and technical staff are available in a protected slot. Confirm the resources with production planning before accepting the date.
Should development trials use a separate line?
Use separate instructions, identified materials and controlled output. The intended production line may be the best trial location if its time is protected and the approved setup is restored afterwards.
What if the factory engineer is unavailable?
Check whether a competent deputy can cover the required decisions. Otherwise hold the affected trial work and rebook with the necessary expertise present.
Should I delay a product change until peak season ends?
Delay approval if representative trials are unavailable. Agree the conditions for rebooking, rather than assume the end of peak season proves readiness. Contain work affected by unresolved faults.
