What is the stage-gate process?

Stage-gate process is a project management and product development method that divides the process into sequential stages separated by control points (gates).

At each stage, a specific set of tasks is performed, and at the gate, results are evaluated and a decision is made:

• to continue the project,
• to adjust the plan,
• or to stop the work.

This allows systematic control of quality and risks, ensures transparency, and supports informed decision-making at each step of the project lifecycle.

Example stages:

1. Idea and concept
2. Analysis and planning
3. Development
4. Testing
5. Launch

Each gate is a check of readiness to move to the next stage.
