The PBS has been elaborated for the airborne facility's telescope element. The PBS level names have been made consistent with the sidebar on page 3 of this handbook. Figures B-2 through B-5 show a corresponding Work Breakdown Structures (WBSs) based on the principles in Section 4.3 of this handbook. At each level, the prime product deliverables from the PBS are WBS elements. The WBS is completed at each level by adding needed service (i.e., functional) elements such as management, systems engineering, integration and test, etc. The integration and test WBS element at each level refers to the activities of unifying prime product deliverables at that level. Although the SOFIA project is used as an illustration in this appendix, the SOFIA WBS should be tailored to fit actual conditions at the start of Phase C/D as determined by the project manager. One example of a condition that could substantially change the WBS is international participation in the project.
