A stage gate assessment is a review of a project or initiative at key points in its development. It is a tool that is used to assess the progress of the project and to determine whether it should continue to the next phase or be closed. A stage gate assessment reviews the project's performance against key performance indicators (KPIs) and other metrics, as well as an evaluation of the project's risks and challenges. It may also involve interviews with project team members and stakeholders, and a review of the project's documentation and artifacts. The results of a stage gate assessment are used to determine any actions that may be needed to address any issues or challenges that have been identified. Stage gate assessments help ensure that projects are aligned with the organization's goals and that they are being managed effectively.
