Final answer:
The incorrect statement about project management processes is that each process must be performed at least once in a project's lifecycle. Processes are used as needed, and some might be repeated or may not be necessary depending on the project.
Step-by-step explanation:
The statement that is not true about project management processes is: (a) each process must be performed at least once in a project lifecycle. In project management, while many processes are integral to a project's success, it is not strictly true that every single process must be performed at least once.
The necessity and frequency of a particular process can vary based on the project's requirements and scope. Also, the same process can be performed multiple times as the project progresses through its lifecycle.
Project management processes are often categorized by knowledge areas and process groups, providing a structured approach towards managing projects. It's critical to note that the application of processes should be tailored to fit the unique needs of the project and continuously improved upon.
This ensures that processes remain efficient and effective, leading to better project outcomes and enhancing the project team's capability.
Cyclic processes, as referenced in the provided information, may refer to repeated processes that can be part of a larger project management cycle. However, this does not imply that every process is cyclic or must be performed in every project.
