A project is a temporary endeavour undertaken to create a unique product, service, or result.– Definition from PMBok Guide

In the real world, a project is unique with inter-related tasks, which has defined start and finish times whose purpose is to achieve a common objective.

• temporary – having a definite start and finish
• unique – the product or service is different in a significant way from all similar products or services.
