Function Point Analysis: One Size Fits All

Software Track



There are many challenges when faced with creating estimates for software development projects. However, without a doubt the single largest driver for cost, effort and duration is project size.
The typical approach to sizing a software project, if it is tried at all, is to “estimate” software lines of code (SLOC). While this may be the most expeditious method, history has shown that this approach usually produces highly inaccurate estimates.
IBM developed function points as an alternative method to bring about more consistent and accurate project sizing for use in software project estimation. This methodology, while not a perfect solution, has enjoyed great success in more than 30 years of use world-wide.
This presentation will provide a brief overview of the International Function Point Users Group (IFPUG) Function Point sizing methodology, its key concepts, as well as strengths, limitations and misconceptions.
Function point based metrics, FP based contracting and other key uses for FPA will be covered. The presentation will also detail why FPA is preferable to SLOC or other sizing methods when creating software development project estimates.
