How We Execute · Stage 04

Coordinated
Production

"Milestones are commitments, not estimates."

Production is coordinated against a confirmed schedule, with defined milestone notifications. It begins only after drawing approval, sample approval, and material verification are all complete. Changes during production are handled through a structured written change process — not by verbal instruction.

What We Do — Stage 04

Four things that happen
at this stage.

Every action at this stage is documented. Nothing proceeds on verbal instruction alone.

01
Confirm production schedule against lead time
A production schedule is confirmed in writing after all pre-production approvals are complete. The schedule defines key milestones and is shared with the client.
02
Coordinate with manufacturing facility
JBL Metal coordinates with the production facility to ensure the confirmed specification, approved sample, and verified materials are all in place before weaving or fabrication begins.
03
Provide milestone notifications
Key production milestones — production start, mid-point check, completion — are communicated to the client proactively. We do not wait to be asked.
04
Handle changes through a written change process
If any specification change is required during production, it is documented in a written change request, assessed for impact on timeline and cost, and confirmed in writing before the change is executed.

Non-Negotiable Rules

What we will not
compromise on.

These rules are not preferences. They are fixed operating standards. They exist because the cost of bypassing them — in rework, in project failure, in client trust — always exceeds the short-term convenience of bypassing them.

Production starts only after all three gates are passed
Drawing approval · Sample approval · Material verification. All three must be complete. There are no partial starts.
No verbal change orders
All production changes are documented in writing. A verbal instruction to change something does not constitute an authorised change.
Milestone notifications are proactive
We do not wait for the client to ask for updates. Milestone status is communicated on schedule.
Evidence Available

What documentation
exists for this stage.

These records are available on request. Trust is built on documentation, not on declarations.
