Missing or imprecise requirements can lead stakeholders to make incorrect assumptions. A "not a problem" defect report (NaP) describes a software behavior that a stakeholder regards as a problem while the developer believes this behavior is acceptable and chooses not to take any action. As a result, a NaP wastes the time of the development team because resources are spent analyzing the problem...
Customer-reported field failures provide valuable information for the requirements of the next release. Without a systematic approach, the requirements of the next release may not address the field failures, and the same problems may reoccur. In this paper, we propose a procedure for improving performance requirements based on a retrospective analysis of field failures reports and original requirements...
Our performance-testing approach required manually inspecting the performance logs. During the project's development, JUnit-based performance testing tools, such as JUnitPerf, weren't available. Such tools provide better visibility of performance problems than manual inspection of performance logs. Although we believe manual inspection of performance trends is necessary, specifying the bottom-line...
Underspecified performance requirements can cause performance issues in a software system. However, a complete, upfront analysis of a software system is difficult, and usually not desirable. We propose an evolutionary model for performance requirements specifications and corresponding validation testing. The principles of the model can be integrated into agile development methods. Using this approach,...
