I would say that the planning process is among the most important phases followed by the execution process. This is because the planning process is the time where a project’s execution is discussed and where all things leading up to the finalization of said project is also discussed and laid out so that every member of the team knows what to expect. A carefully planned and thought-out project can make the execution process run smoother, which is crucial since it is usually the process that requires the most activity and time to complete. The planning process can often overlap during the time the execution process is going on since in industry planning does not necessarily end at the onset of a project’s execution (time is of the essence).

With regard to that, I would say the closing process to be the “least important” process; however, it does not mean it is negligible when it comes a project’s completion. It simply entails that a project’s execution is coming to and end and any finalizations can be looked at to ensure the validity of the project. A well thought plan in the planning process and a good execution following that planning process can ensure that the closing process will result in a successful project.
