A project phase transition says that a project may change from one phase to another. A project can, for example, go from the phase "Acquisition" only to "Construction". The subject "Project Phase Transitions" registers the allowed transitions. The screen has these fields: - "Number": the unique sequence number of the transition. - "Project Phase Old": the phase the project has before the change. The field can be empty for the first phase of a project. - "Project Phase New": the phase the project has after the change. - "Project Cluster Old": optional. The project cluster the project has before the change. - "Project Cluster New": optional. The project cluster the project has after the change. - "Explanation": an optional note of the administrator on the meaning of the transition. See [[Invantive Estate/Concepts/Project|Project]].
