Unadjusted function point count (UFP) The measure of the functionality provided to the user by the project or application. It is contributed by the measure of two function typesódata and transactional. ( Reference : IFPUG CPM 4.1)
Unadjusted Function Point Size The result of the first stage of performing Function Point Analysis. The unadjusted function point size is the functional size of the software delivered (processes and data). The result has not been adjusted for the technical and quality features of the software delivered. ( Reference : Total Metrics)
Unit A quantity adopted as a standard of measurement. Each unit has an associated scale. ( Reference : ISO/IEC JTC1/SC7:14598-3)
unit (1) A separately testable element specified in the design of a computer software component. (2) A logically separable part of a computer program. (3) A software component that is not subdivided into other components. [IEEE-STD-610] ( Reference : SEI:SW-CMM)
Unit of measurement a particular quantity, defined and adopted by convention, with which other quantities of the same kind are compared in order to express their magnitudes relative to that quantity Units of measurement have conventionally assigned names and symbols.
