Meaning
Quality control framework that divides the development process into distinct phases separated by evaluation points. Each stage gate validation requires the project team to meet specific criteria before receiving approval and funding to move to the next part of the cycle. This structured approach prevents the waste of resources on products that do not meet technical or market requirements.
Decision Points
Senior management reviews the progress at each gate to decide whether to continue the initiative or cancel the funding. A successful stage gate validation provides the evidence needed to justify the next level of investment. These reviews focus on the technical feasibility, the competitive landscape, and the projected return on investment.
Risk Management
Identifying flaws in the design or the business case early in the process reduces the cost of failure. If the stage gate validation reveals that a prototype cannot be manufactured at the required cost, the project is redirected or stopped. This saves the organization from the much higher expense of a failed production launch or a product recall.
Operational Discipline
The process ensures that all departments are aligned on the project goals. Consistent documentation and clear metrics allow for an objective assessment of readiness.
