And a VERY IMPORTANT note on PROCESS
The WBS must belong to the project team. This means it should be created by the team, not by an individual and handed to the team. The WBS should be developed in a team setting, with the core team from the various functions represented. A Small Group Dynamic (SGD) occurs in team sizes from four to six persons, such that team members form close alliances and hold themselves accountable for results. Cross-functional teams of this size develop the full WBS through a series of meetings, with the higher level team members developing the higher levels of the WBS and the lower level team members working in separate groups to develop the lower levels.

We strongly recommend that the WBS be developed in a team setting first, and input the information into your computer program only after the team has build it “hands-on.”
