Critical-to-Quality Definition

Not every specification has the same importance. FactoryFrontier helps define Critical-to-Quality points so factories know what must never drift, what can be controlled by sampling, and what should be measured at every important stage.

Why This Is Needed

Without CTQ definition, factories may over-focus on visible appearance and under-control critical performance parameters. This causes products that look acceptable but fail functionally, mechanically, electrically, or in field use.

What FactoryFrontier Does

  • Identify critical dimensions, functions, materials, torque points, safety checks, test outputs, and visual limits.
  • Define which parameters require 100% inspection, sampling inspection, process control, or engineering review.
  • Align CTQ standards with drawings, BOM, test plan, golden sample, and acceptance criteria.
  • Translate product performance risk into factory inspection language.

What You Receive

  • CTQ definition sheet.
  • Inspection priority matrix.
  • Acceptance limits for key dimensions, functions, safety, and appearance.
  • Factory-facing quality communication notes.

Quality must be defined before it can be inspected or enforced.
