QCTP gives project teams a shared way to assess a proposal across Quality, Cost, Timing and Performance before committing to implementation.
Do not evaluate a supplier proposal or engineering change by schedule alone. Capture what changes, what must be revalidated, what it costs, when it can be implemented and how the affected product configuration will be controlled.
Requirements, risk, product conformity, validation coverage, acceptance criteria, control-plan updates and residual risk.
Tooling, engineering effort, part price, non-recurring costs, rework, scrap, logistics and assumptions behind the proposal.
Tooling lead time, sample availability, test duration, approval lead time, implementation date and impact on project milestones.
Functional, technical and vehicle-level performance targets, constraints and validation evidence affected by the proposal.
Affected product scope, part numbers, revisions and configuration remain important cross-functional inputs to a QCTP assessment. The P always means Performance: functional results, technical targets and validation evidence.
State the proposed change, reason, affected part and target configuration.
Evaluate quality risk, cost, timing, validation, manufacturing and interface impacts.
Align engineering, supplier, quality, purchasing and plant stakeholders on evidence, resources and timing.
Complete required validations, update controlled documentation and confirm traceability before implementation.

1-time, recurring, tooling, logistics and validation costs have been assessed with assumptions.
Supplier commitments, sample dates, testing, approvals, implementation and recovery plans align.
Functional and technical targets are assessed, and required validation evidence confirms that the change meets acceptance criteria.
A useful QCTP review ends with evidence requirements, action owners, due dates, implementation conditions and an agreed decision record—not just a slide with 4 green indicators.
