Engineering approval is formal authorization by engineering that a design, change, document, or disposition is technically acceptable.
Engineering approval is formal authorization by an engineering function that a design, specification, process change, work instruction, deviation, or disposition is technically acceptable for its intended use. In manufacturing, it commonly indicates that qualified engineering personnel have reviewed the relevant technical information and approved release, use, or continuation under defined conditions.
Engineering approval is often used in document control, change control, nonconformance disposition, production routing, tooling changes, and digital work instruction workflows. It may apply to drawings, bills of materials, process parameters, rework instructions, material substitutions, or as-built conditions that differ from the released design.
It should not be confused with quality approval, production release, customer approval, or regulatory acceptance. Those approvals may be required in the same workflow, but engineering approval specifically addresses technical adequacy, design intent, manufacturability, or engineering authority within the organization’s defined process.
