Project management is too complex. And therefore project management in research is regularly avoided. BUT - researchers can fix that with some simple approaches.
Fix 1: Don't expect others to use your project management tool or approach. Expect you’ll need to do all of the work maintaining and updating the plan.
Fix 2: Don't have a detailed plan covering your entire project or PhD. But do know how long you can spend on your project or PhD.
Fix 3: Use an iterative project management approach. One that checks in against progress and experiments on a monthly basis.
Fix 4: Use a simple project management tool, such as one-page-project-management so that if others need to see the program, they can, but it is not overwhelming.
