Function Point Analysis sizes software for controlled project delivery

Function Point Analysis (FPA) provides software development leaders the ability to accurately size software as a management and control technique for successful project delivery. This often leads to function point estimation methods. Quantitative functional software sizing uses multiple functional decomposition techniques (FPA, FP Lite, Quick and Early Function Points (QEFP), COSMIC, and SNAP) to develop an objective and quantifiable measure of business and functional requirements, non-functional technical requirements, and software source code.

Our consultants provide customized FPA sizing expertise to help you move to quantitative decision making.  

Our Function Point Analysis Offerings Include:

Common FPA Use Case Scenarios

Usage of FPA is seen often in these use cases:

  • Manage outsource vendor delivery of software value – Clients outsourcing millions of dollars of software development to vendor partners in exchange for enhancements to existing systems or custom development of new features and functions in existing systems or new systems. FPA is used to set an economic metric for the cost of unit of work as a currency of exchange. Vendors are paid for the function points they deliver.
  • Software Estimation - Accurate sizing allows you to effectively manage requirements’ definition and scope and provides an objective input into parametric estimation models. These models provide predictive and retrospective information about past and future project performance for management insight.
  • Continuous Improvement Support  – Competitive software organizations sustain a culture of continuous improvement by measuring cost and performance of their teams and methods. Cost and performance metrics, across an enterprise, can be normalized and used to compare how well teams, lines of business and portfolios are doing from an economic and engineering viewpoint using FPA.
