The IFPUG Guide to IT and Software Measurement

The International Function Point Users Group (IFPUG) is a nonprofit, member-governed organization. The mission of IFPUG is to be a recognized leader in promoting and encouraging the effective management of application software development and maintenance activities through the use of Function Point Analysis (FPA) and other software measurement techniques. IFPUG endorses FPA as its standard methodology for software functional sizing. In support of this, IFPUG maintains the Function Point Counting Practices Manual (CPM), the recognized industry standard for FPA. In order to complement the functional aspect of measuring software size, in 2011 the Assessment Practices Manual (APM) was released by IFPUG. The APM provides a quantifiable measure for the non-functional size of software development by means of documented guidance, definitions, and practices about non-functional software features and related sizing criteria. The chapter within this book titled "Software Non-functional Assessment Process (SNAP)" introduces the concept.

IFPUG also provides a forum for networking and information exchange that promotes and encourages the use of software product and process metrics. For further information on IFPUG, please visit www.ifpug.org
