ABSTRACT
Deriving Metrics as a Key Performance Indicator Measurement is essentially a mapping process. The primitive man counted sheep by mapping his cattle, one to one, to a bundle of sticks. If a sheep is missing, it will show up as a mismatch. Word was not yet invented, but there was mapping all the same. A similar mapping is performed for function point counting; measurement is seen as a “counting process,” a new name for mapping. The mapping phase in measurement is well described in the COSMIC function point manual. With the help of language, we have given a name for what is counted-software size. With the help of number theory, we assign a numerical value applying rules.
