Measuring the Use of Features in a Requirements Engineering Tool-An Industrial Case Study
Andreas Borg, Jenny Karlsson, John Gerhard Olsson, Kristian Sandahl · 2004
Measuring how features are actually used in a system has several potential benefits, for instance an improved requirements selection process. We have investigated how the use of features in Focal Point—a highly interactive, web-based RE tool—can be measured using log-file analysis, and we have interviewed key persons (user, developer, and consultant) in order to validate and discuss the deployed method as well as the results. Our measurements show that different view and edit features are dominating. There is a 90 % agreement between measured use and other sources such as interviews with stakeholders and an automated solution based on direct mapping from accesses of certain.jsp-files (JavaServer Pages) to feature categories. All stakeholders believe that the information generated is useful, but the development manager would like more detailed information based on logging individual mouse-clicks.
