NASA WORK BREAKDOWN STRUCTURE (WBS) REFERENCE GUIDE (MAY 1994)

NASA WORK BREAKDOWN STRUCTURE (WBS) REFERENCE GUIDE, PROGRAM/PROJECT MANAGEMENT SERIES (MAY 1994)., The work breakdown structure (WBS) is an effective tool in managing NASA programs and projects. It assists both NASA and contractors in fulfilling management responsibilities. In accordance with NASA Handbook 7120.5, Management of Major System Programs and Projects, a WBS is mandatory for major system acquisitions and major projects, and will be used for other projects when practical. A WBS is required when performance measurement is applied to a contract. The purpose of this WBS reference guide is to support the completion of program and project objectives within budget and schedule constraints. This reference guide can be used for various work efforts including research, development, construction, test and evaluation, and operations. The products of these work efforts may be hardware, software, data, or service elements (alone or in combination).
