Abstract:
The “Early & Quick Function Points Approach (E&QFPA)” is a mean to approximate the results of some standard Functional Size Measurement Methods like IFPUG, SiFP or COSMIC. E&QFPA is a set of concepts and procedures that, even when applied to non-detailed functional specifications of a software system, maintains the overall structure and the essential principles of standard functional size measurement methods. The E&QFPA combines different estimation approaches in order to provide better approximations of a software system functional size: it makes use of both analogical and analytical classification of function types (transactions and data). Moreover, it allows the use of different levels of detail for different branches of the system (multilevel approach). This paper illustrates the basic concepts of the method which is mature and well established in the Italian market, as well as the results of an empirical validation experiment conducted on a real business data set of IFPUG function point measures. The usage of such a method may contribute to the rapid quantification of user requirements very early in the production life cycle.
