User requirements address two different types of qualities: pragmatic qualities (PQs), that address system functionality and usability, and hedonic qualities (HQs) that address the stakeholder's psychological well-being. Studies show that users tend to describe such satisfying UXes mainly with PQs, and that some users seem to believe that they are describing a HQ when they are actually describing a PQ. Question/Problem The problem is to see if classification of any user requirement as PQ-related or HQ-related is difficult, and if so, why. Principal Ideas/Results We conducted a controlled experiment in which twelve requirements-engineering and UX professionals, hereinafter called \"classifiers\" classified each of 105 user requirements as PQ-related or HQ-related. The experiment shows that neither (1) a classifier's involvement in the project from which the requirements came nor (2) the classifier's use of a detailed model of the qualities in addition to the standard definitions of \"PQ\" and \"HQ\" has a positive effect on the consistency of the classifier's classification with that of others. Contribution The experiment revealed that classification of user requirements is a lot harder than initially assumed.","PeriodicalId":176958,"journal":{"name":"2017 IEEE 25th International Requirements Engineering Conference (RE)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127997820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
