Unformatted text preview: Reviews. Software reviews are scheduled by
the program/project manager for the purpose of
ensuring that software specifications and associated
products are well understood by both program/project
and user personnel. Throughout the development cycle,
the pedigree, maturity, limitations, and schedules of
delivered preproduction items, as well as the Computer
Software Configuration Items (CSCI), are of critical
importance to the project's engineering, operations, and
Readiness Reviews. Readiness reviews are conducted
prior to commencement of major events that commit
and expose critical program/project resources to risk.
These reviews define the risk environment and address
