3.3 Identifying assumptions
Identifying assumptions is often an iterative process, which starts from the objectives and activities that are defined in the narrative summary column.
You then identify the assumptions that you are making about external factors which are necessary for success. In the process you define the boundary between what is internal and what is external to the project.
It may then be necessary to redefine the objectives or activities to ensure that they are consistent with the formulation of the assumptions. You may need to go through several iterations of the process, considering different boundary-setting options, before you are satisfied with the result.
