30+ years of development experience here. The #1 management tool that really works is a simple prioritised list. Whether you are managing a team or yourself. Tasks gets assigned in priority order and if a task is blocked then you pause and pick the next one on the list. The prioritised list is also excellent for negotiating with stake holders. Simply ask them to place what they want in the priority list. It makes it really obvious to the stakeholders what the trade offs are.
