Applying Software Development Risk Taxonomy in Use Case Points Complexity Factor

The studies of software development risk continues to grow. One is the software development risk taxonomy released by Software Engineering Institute (SEI). Unfortunately, no risk management research has been explicitly combined with software size estimation. Therefore, this study aims to apply risk management over 13 technical and eight environmental factors in the Use Case Points (UCP) method. The dataset consists of 345 risk factors by any sources, then mapped and justified by three experts. This mapping generates the risk frequency, which is finally modified by adding it to the origin weight by UCP. The results of the application of risk to environmental factors dominate as much as 76.81 percent compared to technical factors. There are 2 objects that the most influencing risks, such skill and motivation for both the developer team and end-user. For further research, this study still challenges how risk management can be integrated to obtain better accuracy toward software effort estimation.
