Configuration Management Glossary

Refers to fit-for-use, which translates to the ability to mate with other parts (Hardware: includes dimensions and tolerances, and Software: includes requirements for memory, disk space, and processing power) and conformance to any relevant manufacturability and serviceability requirements.

Refers to the appearance/esthetic requirements of a part. Things like shape/geometry, relative size, viscosity (when it concerns visual appeal), volume, look and feel.

Abbreviation: FBL

Quantitative performance parameters and design constraints, including operational and logistic parameters and their respective tolerances. Functional characteristics include all performance parameters, such as range, speed, lethality, reliability, maintainability, and safety.
_{Source: MIL-HDBK-61B}

The formal examination of functional characteristics of a Configuration Item or system to verify that the item has achieved the requirements specified in its Functional Configuration Documentation or Allocated Configuration Documentation.
