What are Simple Function Points
Simple function points (SFP) are a quick-to-learn and quick-to-use software functional size estimation technique. The fundamentals of SFP are aligned with first generation IFPUG function points, less precise but quicker to get a first estimate. SFP are an approximation of IFPUG FP by treating all data functions as average in size. This simplification means there is no need to know all data element types (DETs) nor Record Element Types (RETs) , it treats all object types as equivalent in size and complexity. A similar approach is applied to the Data Transactions, these too are all treated as equivalent in size. The combination of these two short cuts, makes SiFP to be a fast way to estimate the size of any system.
ScopeMaster® automates sizing in SFP (as well as IFPUG and COSMIC Function Points).
One of the problems with traditional IFPUG sizing (although not a problem for COSMIC) is that the information required to count function points according to the rules is often not available at the stage when knowledge of the size is most important. SFP is a simplified sizing technique designed to address this problem.
Simple Function Points are a simplified approach to estimating IFPUG function points. The concepts are the same, but the analysis required is less detailed and much faster to perform. SFP do not require the level of detail necessary for an IFPUG count. SFP is not compliant with the ISO standards that apply to an IFPUG or COSMIC size. SFP have grown in popularity in the last two years, especially in the USA.
