In the second example, the overall project version is not the same as the sum of the agile sprint counts, because some of the functions are counted twice as part of sizing the sprint. Specialized data communications are required. Calculations, derivation of data, or maintenance also takes place. The functional requirements are reflected in the functional size, the non-functional requs need to be input in an estimation model. For the transactional functionsEIs, Eos, and EQsthe complexity factor is based on the number of data element types that cross the application boundary as well as the number of file types (ILFs and EIFs ) referenced or maintained.

The accuracy of FPA is very difficult as multiple factors are involved on it. Function point analysis is one such technique: FPA is a method to break systems into smaller components, so they can be better understood and analyzed. Determine the number of data functions (ILFs and EIFs); Calculate the total unadjusted function point count of the application as follows: indicative size (fp) = 35 x number of ILFs + 15 x number of EIFs. A challenge of any project manager is to control scope creep, or the increase of the scope. Thanks for helping keep SourceForge clean.
