contains all of the technical requirements and related
cost and schedule requirements that are sufficiently
mature to be accepted and placed under change control
by the NASA project manager. The project baseline
consists of two parts: the technical baseline and the
business baseline. The system engineer is responsible
for managing the technical baseline and ensuring that it
is consistent with the costs and schedules in the
business baseline. Typically, the project control office
manages the business baseline.
Configuration management requires the formal
agreement of both the buyer and the seller to proceed
according to the up-to-date, documented project
requirements (as they exist at that phase in the project
life cycle), and to NASA Systems Engineering Handbook
Management Issues in Systems Engineering
change the baseline requirements only by a formal
configuration control process. The buyer might be a
NASA pro gram office or an external funding agency.
For example, the buyer for the GOES project is NOAA,
and the seller is the NASA GOES project office.
management must be enforced at all levels; in the next
level for this same example, the NASA GOES project
office is the buyer and the seller is the contractor, the
Loral GOES project office. Configuration management
is established through program/project requirements
documentation and, where applicable, through the
contract Statement of Work.
Configuration management is essential to
conduct an orderly development process, to enable the
modification of an existing design, and to provide for
later replication of an existing design. Configuration
management often provides the information needed to
track the technical progress of the project since it
manages the project's configuration documentation.
(See Section 4.9.2 on Technical Performance
Measures.) The project's approach to configuration
management and the methods to be used should be
documented in the project's Configuration Management
Plan. A sample outline for this plan is illustrated in
Appendix B.6. The plan should be tailored to each
project's specific needs and resources,...
