Final answer:
The incorrect statement about phase-to-phase relationships is that planning for an iterative phase begins when the work of the previous phase is progressing. Iterative development involves planning and execution in cycles throughout the project, not after the progression of a previous phase. The incorrect option is no 4.
Step-by-step explanation:
The question pertains to the phase-to-phase relationships in project management. Phase-to-phase relationships refer to how different stages of a project interact with each other, and to what extent their activities are dependent or independent. These relationships can greatly affect how a project is executed and managed.
The first point indicates that handoffs occur after a phase-end review in an overlapping phased project. This is true; in an overlapping project, while one phase is coming to an end, the next phase is already starting, and a review helps to facilitate the handoff of work.
The second point states that during sequentially phased projects, the previous phase must finish before the next phase can begin. This is a characteristic of the traditional waterfall methodology, wherein a linear and sequential approach is followed, and is indeed true.
The third point suggests that fast-tracking is a compression technique that can be applied as a phase-to-phase relationship. This is also true as fast-tracking means that phases or activities that are typically done in sequence are performed in parallel to save time.
The fourth point says that planning for an iterative phase begins when the work of the previous phase is progressing. This doesn't fit the definition of iterative development because in an iterative approach, planning and execution are done in cycles throughout the project, and not necessarily after the previous phase's work is in progress.
Therefore, the statement that is not true regarding phase-to-phase relationships is the fourth one. Iterative phases are part of an ongoing development process rather than being dependent on the completion or the progression of the previous phase.
