A project management model which uses a five-stage phase-gate process to help structure and speed-up new product development projects.

Each stage consists of activities (the work that must be done) and an integrated analysis (of all the functional activities) which result in the creation of deliverables. Similarly, each gate is composed of one or several deliverables (resulting from the stage it closes) and criteria (usually both financial and qualitative, and organised in a scorecard), which result in an output or decision.

Planisware is one of a small number of software solutions worldwide to achieve Stage-Gate® Ready certification.
