Detailed function point analysis - This is the usual function point analysis method and is performed as follows: if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[250,250],'cio_wiki_org-box-4','ezslot_4',117,'0','0'])};__ez_fad_position('div-gpt-ad-cio_wiki_org-box-4-0');2. Abbreviated as FPA, functional point analysis is one of the mostly preferred and widely used estimation technique used in the software engineering. The International Function Point Users Group (IFPUG) defines an adjustment that may be made for environmental factors, called the Value Adjustment Factor (VAF). Function Point 3. Total Page of Documentation (PD) =Software Technical Documents + User related documents, Cost of each Functionalities = COSTProductivity. Whether to count by sprint or by project depends on the goals of the metrics program. The FAST diagram, whose initials stand for Function Analysis System Technique, is a diagram: constructed from left to right, which represents the logical relationships between different functions, to answer the questions how and why. In this article, Dan demonstrates the use of FPA in agile development through a hands-on example. So, break-even is, Revenue - Total Costs = 0. The input datas are processed by the application to stored in a file with logical structure. It also measures the software . Calculate the Complexity Adjustment Factor (CAF) It will not be applied for this example. called the Function Point index which measures the size and complexity Objectives of FPA: The objective of FPA is to measure the functionality that the user requests and receives.
