PROJECT APPROVAL PROCESS

Convert decisions into project records.

A repeatable approval process connects the buyer brief, product and packaging definition, sample status, validation scope and production release. It reduces ambiguity without pretending every project uses the same document set.

Visual context supports the workflow explanation; project evidence remains model-, supplier- and configuration-specific.
MANUFACTURING SCOPE

Define the route from the actual change request.

Approval is not a single final signature. Commercial, product, artwork, engineering, validation and production decisions occur at different points and should reference the correct configuration.

Request a route review
GOOD FIT

This route is suitable when:

  • Multiple teams approve product, brand, compliance or production
  • The program includes custom packaging or market-specific files
  • Samples will change through several review rounds
  • Repeat orders require a stable configuration baseline
REVIEW ANOTHER ROUTE

Additional qualification is needed when:

  • A verbal confirmation is treated as specification approval
  • Artwork, sample and production changes are mixed in one message thread
  • Destination-market requirements remain undefined at release
  • The approved sample cannot be linked to the production configuration
ENGINEERING WORKSTREAMS

Each workstream ends with a reviewable output.

Files and validation activities are agreed for the selected product, development depth and destination market.

PROJECT ROUTE

Move forward through visible decisions.

Open issues need a written disposition before the next cost, tooling, validation or production commitment.
