Meaning
A series of structured operational milestones governs the progression of a product development project from initial concept to commercial production. These requirements, known as stage gate criteria, must be satisfied before a project receives funding to move into the next phase of development. They act as quality filters to identify underperforming projects early in the development lifecycle.
The criteria stop applying once the product completes its launch and transitions to routine operations.
Evaluation Metric
Financial and technical benchmarks are established at the start of each phase to measure progress. These metrics include projected manufacturing costs, market size estimates, and preliminary prototype yield rates. Setting clear stage gate criteria prevents the project team from moving forward with a product that is too expensive to manufacture.
Decision Point
Cross-functional steering committees evaluate the project against the pre-established requirements at the end of each development phase. The committee must decide to either approve, hold, recycle, or terminate the project. This rigorous review under the stage gate criteria ensures that only projects with a high probability of success proceed.
Resource Allocation
Funding and personnel are released incrementally to reduce the company’s financial risk in the early, highly uncertain phases of a project. As the project advances and risk decreases, larger capital budgets are unlocked for manufacturing scale-up. Diligent application of stage gate criteria prevents the waste of corporate resources on dead-end initiatives.
