24th CIRP Design Conference Qualitative comparison of requirements elicitation techniques that are used to collect feedback information about product use
Stefan Wellsandt, Karl Hribernik, Klaus‐Dieter Thoben · 2014
User-centric design requires the application of different techniques to elicit user requirements. Many of these techniques deduct requi rements from feedback information concerning a product’s actual use. Typical approaches are inquiry and observation of users. While most techniques co llect subjective use information, novel techniques, such as product-embedded sensors, can retrieve objective data that can be further pr ocessed. The paper compares a selection of eight techniques used in requirements elicitation. The techniques are evaluated according to six q ualitative criteria with a focus on the terms of information collection and the qualities of that information. The qualitativ e results are illustrated through net-diagrams that can be used to further argue on the techniques, especially in areas where requirements for individual users need to be elicited.
