About Simple Function Points (SFP)

Simple function points are a quick approximation of IFPUG function points. ScopeMaster performs the language analysis on the requirements sufficient to detect the Data Groups ( DG) and transactions or elementary processes (EP).   Determining SFP from a set of requirements requires some judgement.  For example if an object type (DG) occurs just once within a set of requirements, is it really a DG? or perhaps it is just a typo within one user story. ScopeMaster assumes that all detected functional objects are legitimate.

Using ScopeMaster to Automatically estimate SFP

ScopeMaster is able to help accelerate both full IFPUG FP counting and SFP counting.  A set of requirements should be added to ScopeMaster via the UI (or as a CSV upload).  Once added, you then need to initiate the analysis of the requirements.  Once the analysis has completed, the SFP report can be viewed and the new sfp API endpoint will expose SFP information as shown below.

At this time we are exposing the simple function point information necessary to integrate with parametric planning tools.
