Definition of Project Management

One way to simply and intuitively define project management is that it is a set of tools, templates, and processes designed to answer the following six questions:
1. What business situation is being addressed by this project?
2. What do you need to do?
3. What will you do?
4. How will you do it?
5. How will you know you did it?
6. How well did you do?
