Comparative Selection of Requirements Validation Techniques Based on Industrial Survey
Sammanfattning: In software engineering the requirements validation has very core importance. The requirements validation very helpful to judge that software requirements specification (SRS) is complete and free of bugs. The requirements validation is a assurance that the software requirements document is free of unwanted requirements and completely consistent. In order to remove inconsistency, detect defects and make the software requirements document fully functional the requirements validation is key factor. All possible requirements validation techniques available in academia such requirements reviews , requirements prototyping, requirements testing and viewpoint-oriented requirements validation are explained properly in this thesis report. In a very readable and understandable way the thesis presents all pros and cons of these requirements validation techniques practiced in different software companies in Sweden and available in academia. This report explains all possible advantages and issues related with these RVTs. In order to judge the best performance of these RVTs and to make their comparison I used a proper channel. I have designed a very effective survey questionnaire with the help of my colleges and literature review. To make creative comparison I conduct interviews and send survey questionnaire to different people working in requirements engineering departments in different software industries in Sweden. Finally the satisfaction levels of different software industries with these requirements validation techniques presents in this thesis report. These variables such as defect detection, time and cost are used to measure the satisfaction levels.
