Scope detail
A product family, a reference design and the inputs that vary between orders.
Start with your accepted decisions, tested components and existing design. Adapt what needs to change for the next order. Agree the outputs, checks and acceptance criteria; we carry the assignment through review and correction.

Agree the work, the evidence and the people responsible before we begin.
A product family, a reference design and the inputs that vary between orders.
Which variants are in scope, which methods can be reused, the output formats and who accepts the result.
The agreed model, drawings and quantities, with check evidence and the review record. Open or excluded items remain explicit; release follows the authority agreed for the assignment.
Elapsed time from complete inputs to accepted package, plus engineering, checking and rework effort.
Start with a bounded family. A new product concept, a new structural method or an unqualified supplier catalogue needs separate work.
A request in an email can affect a drawing, a component and a check. Keep the reason connected to the work.
“Increase the duty.”

Three sources. One design to keep in step.
Illustrated workflow, not a live engineering run. Automated updates depend on supported methods and agreed scope.
