What do you mean by "planning"?
We prefer a more comprehensive definition of the term "planning", namely:
- The process of identifying the objectives, the means, the resources, actions and responsibilities necessary to accomplish a project goal
This definition is much broader
- Which is why we have "WBS & Planning" as a separate set of Issacons
Nevertheless, scheduling is an intrinsic part of planning
- So, we may use it either way!
