Project Size

Project Size

Project Sizing guidelines assist in determining the size of a project and the minimum level of project documentation and governance required to enable the project's success.
The result of the sizing assessment is a clearly defined and accepted agreement as to how the project will be managed and the level of detail and discipline to be employed.
Project size is determined using a total rating after considering the various elements of the project.
