  2. 2. ©2012 David Consulting Group• Function Point Analysis (FPA) is an industry best practice software-sizing technique.• FPA provides a quantitative value of size based on the functions andfeatures being provided to an end user.• FPA is a well-defined process, which results in a consistent and easilyunderstood measure of size, based on user requirements.• The resulting size is often viewed as a measure of value to the enduser.1What is Function Point Analysis?
  3. 3. ©2012 David Consulting GroupHow Does it Work?• Function point sizing considers the functionality that has beenrequested by an end user and has been provided to that end user.• The functionality is categorized as pertaining to one of five keycomponents: inputs, outputs, inquiries, interfaces and internally-retained data.• A Certified Function Point Specialist uses available documentation andexpert knowledge to identify the five key components.• Each of the components is evaluated and given a prescribedweighting, resulting in a specific function point value.• When complete, all functional values are added together, resulting in atotal functional size of the software deliverable.2
  4. 4. ©2012 David Consulting GroupWhat are the Benefits of FPA?3Function point analysis has many uses and benefits:• It allows for a comparative measure of size among various softwaredeliverables.• It is a key input parameter (along with complexity) to provide moreprecise project estimates.• It serves as a normalizing factor for key software measures.• It serves as a critical measure of evaluating software processeffectiveness.• It provides the ability to make comparisons to industry benchmark data.• It allows for the proper setting of end user expectations regarding theanticipated size of the software deliverable.
  5. 5. ©2012 David Consulting GroupWho Would Benefit from FPA?• PMOs/ PMs – provides the capability to improve their ability to manageand control project deliverables.• BAs – provides the ability to ‘size’ the required features and functionsand can be a useful tool in managing customer expectations.• Software Estimators – provides a key parameter for estimating.• Performance Measurement Specialists – serves as a normalizingfactor when analyzing benchmark data.• Outsource Governance Managers – provides the ability to measure thecost per unit of work.4
