Project planning as the majority of the posts above indicated is important and overall sets the foundation and path moving forward for the project. The planning phase I do agree that returning to activities at an earlier phase doesn’t mean we are moving backwards. There are things within a project that may not necessarily be accounted or predicted which would require a team to get back to the drawing boards and rethink some aspects of the project. Essentially, this is progress even though it is within an earlier phase of the project. Overall, within the initial phases of setting up a timeline there should be some buffers that would allow for unforeseeable circumstances to be accounted for. A schedule should not be solely constructed based on the idea that everything goes according to plan. There should be some form leeway allowed within the schedule to allow for circling back to the planning phase if something unforeseeable were to occur.
