Welcome to DCG’s Function Point Analysis: Sizing the Software Deliverable Series. Function Point Fundamentals is the first course in a series of courses built to help you become a proficient counter, and should you choose to do so, become a Certified Function Point Specialist (CFPS).
Function points were introduced in 1979 by Alan Albrecht, from IBM. IBM needed a way to quantity the size of their projects in order to provide a better estimation model for their workload. Function points was the answer and in 1986 the International Function Point Users Group was chartered to be the governing body for the function point methodology. IFPUG is a not-for-profit organization consisting of an elected board of directors, and several committees devoted to supporting, developing and implementing consistent and accurate counting guidelines. The Counting Practices Committee (CPC) develops the counting guidelines and the Counting Practices Manual (Documented Rules), the New Environments Committee (NEC) applies those guidelines to new technologies and produces white papers and case studies for use by the IFPUG membership, the IT Performance Committee explores the use of function points in benchmarking and estimation modeling, and other committees oversee the certifications provided by IFPUG. Benefits of being an IFPUG member include reduced pricing for conferences and IFPUG training during the conferences, access to resource material (e.g. articles and white papers), and networking capabilities with the IT community that shares a common interest in metrics and function points.
Function points only address the functional requirements and are from a logical view not a physical view. A typical developer would be looking at programs, physical database tables, and physical screens. We as function point specialists (counters) look at the functionality provided by the screens (transactions), logical data groupings of tables, and the ability of the application to perform a complete process. Typically, business user requirements reflect the logical view.
Which of these things are the most important to you or frustrating or challenges…
This slide concludes the class sessions. This is the first of several classes that we offer in the use of function points. If you want further mentoring or training for the individual or the organization, please contact Fiona Thompson at the DCG Headquarters or Sheila Dennis in the Colorado offices.
