A Project is a temporary set of actions which aim to create a unique, final deliverable.
This concise project definition reveals the major differences between characteristics of projects and operations:
- Is temporary which means that is subject to change at a certain moment. In fact since it might change at any moment in time makes it rather transient than temporary.
- Its outcome is unique. Although the product or service may be included in a large category (e.g. a building, a software product), the details can give the uniqueness of a project result.
A similar definition can be found into A Guide to the Project Management Body of Knowledge (PMBOK® Guide): “A temporary endeavor undertaken to create a unique product or service”.
