A project can be divided into any number of phases. A phase is a collection of logically related activities in order to complete one or more deliverables. Project phases can be sequential or overlap, and it depends on the situation. A Project is separated into different logical groups which are called phases for the purpose of management, planning and control. The number of phases in the project depends on the size, complexity and impact of the project. Every phase needs to go through all the 5 process groups. During closing of the phase the product can be handed over to the customers for review, and based on the feedback, the next phase starts. Most of the projects have the below types of phase-to-phase relationship. One of the given below is not a valid phaseto- phase relationship. Which one is it?

Valid phase-to-phase relationship is?
