This document describes an experiment to evaluate methods for simplifying the use case points (UCP) software effort estimation technique while maintaining accuracy. The experiment analyzed 14 projects to test hypotheses around simplifying factors like actors, transactions vs steps, and technical/environmental factors. Results found that transactions outperformed steps, many factors had minor impact or overlapped and could be removed, and total steps or transactions could estimate effort nearly as well as UCP with simpler calculations. Threats to the study's validity were also addressed.
