Range-based cost planning

Working brief

Decisions to settle before approval

Compare transparent scenarios that change one driver at a time without presenting their ranges as universal prices. 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 the assumption responsible for each band change
  • Confirm the intended user, use environment and approval owner for worked examples
  • 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.

  • Worked cost-and-MOQ scenarios
  • 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 worked examples 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.

Common question

can I see a worked example of how a toy price is built up

The worked examples compare transparent scenarios that change one driver at a time, so you can see which assumption moved the result. They show the mechanics of a build-up rather than publishing universal prices, and each range belongs to its own scenario only. Use them to work out which of your decisions carries the most cost weight.
