It is desirable WITHIN an organization that the project management process be scalable in accordance with the project size. Big projects need more rigorous and formal on its management than small projects. Using the same approach for any size project means burdening smaller projects with a relatively high cost of management, IE, WASTE of resources.

There is no industry standard definition to define if a project is small, medium or large. This is a relative concept and it must be solved by each organization. In fact, it’s not usually necessary to define a project in 3 levels (small, medium and large). For organi-zations that usually work in a similar way, that classification could be unnecessary and using the same management process for all projects might be the best approach. Some ORGANIZATIONS have a management tactics for just TWO types of projects (small and large). Also, it is not prohibited if an organization wants to define more than 3 levels for the project size; (for example: small, medium, large and extra large). But this is not usual. 

In summary, the concept of small, medium or large is very relative; each organization can establish it own criteria to appoint a project in relation to its size.
