Extended Empirical Comparison of the Two ConjointQFD Approaches and the CC-SEQFD New Approach on the Example of the Smart Home for Elderly People – Study 2

Study 2 consists of the Pullman’s and Baier’s conjointQFD approaches and the CCSEQFD new approach. These approaches are tested on the example of the “smart home” for elderly people. The goal of study 2 is to further investigate these approaches adapted to elderly people and to compare their results directly and indirectly. This study is an extended empirical investigation for study 1 (Chapter 6) with adaptations measures to elderly people as explained in Section 5.3 and Section 5.5. In study 2 conversely to study 1, two levels of adaptations are taken into consideration: by the introduction of a new approach for elderly people and by adaptation measures taken within each approach. Additionally, the examples selected for the study “smart home” is also focused on the elderly and the features are relevant to them.
