Requirement control
Translate customer requirements into measurable optical, electrical, mechanical, environmental, and commercial acceptance criteria.
Quality & manufacturing
Make acceptance criteria explicit before volume.
Reliable supply starts with a shared definition of what will be measured, how it will be measured, and how change will be controlled.
Quality is a chain of controlled decisions.
Product pages describe representative configurations. A purchase specification should define the exact revision, test conditions, limits, sample plan, documentation, packaging, and change notification expectations for the program.
Control points
Four areas to align before release.
Supplier & material control
Define approved sources, incoming inspection, traceability expectations, and escalation paths for critical materials.
Process verification
Use documented process flow, first-article review, yield monitoring, corrective action, and revision control.
Outgoing evidence
Agree sampling, measurement conditions, reporting format, packaging, labeling, and shipment authorization.
