Describe the major approaches in constructing a Work Breakdown Structure, WBS. Various approaches for creating a WBS:
Major Deliverables and sub projects: One could use the major deliverables as the first level of decomposition to begin with.
Subproject executed outside the project team: Once could arrange a WBS on the basis of subprojects as well. Each of the sub project managers then creates a WBS for their project.
Project phases: One could create a WBS based on various phases of the project to begin with, e.g.: Development, testing etc.
Combination: One could mix n match using project phases, and sub projects or key deliverables and create the first level of WBS
