Roadmapping for prioritisation of smartphone feature requirements based on user experiences

Since the life cycle of smartphones is becoming shorter, users are demanding new and improved smartphone features for updated smartphones, but it is difficult to know which features are the most important to users. In Internet user communities, users increasingly review smartphone functions and share information about their experiences such as complaints, problems, and satisfaction, and these user experiences have been fruitful sources for manufacturers that lead to smartphone improvements. Focusing on these user experiences, this paper proposes a systematic roadmapping process including prioritisation of smartphone feature requirements. By prioritising smartphone feature requirements, new and improved versions of smartphones that reflect user needs can be planned based on a product–market roadmap. The systematic approach consists of three parts: user-driven quality function deployment (QFD), a frequent pattern (FP)-tree algorithm, and a product–market roadmap. First, we collected data extracted from text mining in Internet user communities to construct a user-driven QFD. Second, using user experiences related to smartphone features, we applied the FP-tree algorithm to algorithmically derive a priority list of smartphone feature requirements. Finally, based on the result of the FP-tree of smartphones, we proposed guidelines to construct a product–market roadmap. It is expected that a versioning strategy can be formulated through this prioritised product–market roadmap. Furthermore, covering each step from data collection to roadmapping, this study suggests a systematic process for prioritisation of smartphone feature requirements based on user experiences.
