An Approach for Integrating the Prioritization of Functional and Nonfunctional Requirements
Table 6
Overview of empirical assessment performed on IPA.
Goal
Analyze the actual time-consumption property of three different prioritization approaches: IPA, AHP-based, and HAM
Independent variable
Prioritization approaches: IPA; AHP-based, and HAM
Dependent variable and measure
Actual time-consumption (measured as computing the difference between start and end time of the prioritization task); results quality (measured in terms of agreement)
Empirical study approach
Simulated case study with real subject: banking software system; 20 requirements including 15 functional requirements and 5 nonfunctional requirements
