Things to Ensure When Running a Project

I'm compiling a list of things to ensure while running a project. The list will be relevant to me. Yours may be different. A complete list will be infinitely long.

This list will be updated as often as I recognize a need to do so.  Currently, it stands as:

1. Make sure you have a clear delineation of the project scope.
2. Make sure you have a clear and complete list of stakeholders and their expectations of the project deliverables and execution.
3. Make sure the project team is clear on the project plan.
4. Corollary to 3, have a project plan.
5. Always have a valid, real, working schedule and stick to the schedule for as long as the schedule is valid. Update the schedule when needed.
6. Have frequent completions and starts (ie, have milestones). This is intended to instill in the team the plan for the next segment of the project.
