Working brief
Decisions to settle before approval
Learn how design, tooling, electronics, testing, packaging, quantity and delivery affect different portions of project cost. The purpose of this page is to make the buyer's next decision explicit and give the project team a shared review point before cost, tooling or production commitments.
- Identify which decision changes which cost layer
- Confirm the intended user, use environment and approval owner for cost drivers
- Separate required scope from options that can wait for a later version
- Record market, quantity, budget and schedule constraints before approval
What the review should return
A useful review does more than confirm that the project is possible. It records the assumptions, files, risks and approvals that control the next milestone.
- Cost-driver reference library
- Assumptions, exclusions and unresolved-question register
- Representative sample, calculation or validation recommendation
- Next milestone with an accountable reviewer and exit criteria
Evidence buyers should request
These items prevent the page from becoming a generic marketing claim. They should be current, relevant to this product decision and available for review at the appropriate project stage.
- Current cost drivers example, demonstration or worked calculation
- Reviewer-approved specification, diagram, template or methodology
- Relevant sample, test, production or process record
- Dated approval, permission status and revision history
How this fits the project
The planner keeps development, tooling, unit manufacturing, packaging and delivery decisions visible. It helps buyers compare scope before asking a factory to confirm cost and MOQ. For this decision, the team should confirm ownership, reviewers and exit criteria before moving to the next stage.
The downloadable or emailed plan records working assumptions only. Final engineering, quotation, compliance, intellectual-property and schedule commitments belong in the reviewed project scope and signed agreement.
