Difference between project and non project work?

A project is a work effort made over a finite period of time with a start and a finish to create a unique product or service or result. Because a project has a start and a finish, it is also called a temporary effort or endeavor. In other Words, a project is a temporary endeavor taken to create a unique product, service or result. So, a project has two defining characteristics: It is temporary, and it creates a unique result.

Any work that you do, in order to accomplish your project's objectives is termed Project work. Anything else you may do, that would not affect your project is termed non project work.
