Mockups, prototypes, and scenarios are suitable to understand usability issues and user requirements early. Nevertheless, users are often dissatisfied with the usability of a resulting software. Apparently, previously explored information was lost or no longer accessible during the development phase.Scenarios are one effective practice to describe behavior. However, they are commonly notated in natural language which is often improper to capture and communicate interaction knowledge comprehensible to developers and users. The dynamic aspect of interaction is lost if only static descriptions are used. Digital prototyping enables the creation of interactive prototypes by adding responsive controls to hand-or digitally drawn mockups. We propose to capture the events of these controls to obtain a representation of the interaction. From this data, we generate videos, which demonstrate interaction sequences, as additional support for textual scenarios.Variants of scenarios can be created by modifying the captured event sequences and mockups. Any change is unproblematic since videos only need to be regenerated. Thus, we achieve video as a by-product of digital prototyping. This reduces the effort compared to video recording such as screencasts. A first evaluation showed that such a generated video supports a faster understanding of a textual scenario compared to static mockups.","PeriodicalId":382958,"journal":{"name":"2017 IEEE 25th International Requirements Engineering Conference Workshops (REW)","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134460063","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}

Schneider, Oliver Karras, Anne Finger, Barbara Zibell","doi":"10.1109/REW.2017.17","DOIUrl":"https://doi.org/10.1109/REW.2017.17","url":null,"abstract":"Challenges in spatial planning include adjusting settlement patterns to increasing or shrinking populations; it also includes organizing food delivery in rural and peripheral environments. Discourse typically starts with an open problem and the search for a holistic and innovative solution. Software will often be needed to implement the innovation. Spatial planning problems are characterized by large and heterogeneous groups of stakeholders, such as municipalities, companies, interest groups, citizens, women and men, young people and children. Current techniques for participation are slow, laborious and costly, and they tend to miss out on many stakeholders or interest groups.We propose a triple shift in perspective: (1) Discourse is reframed as a requirements process with the explicit goal to state software, hardware, and organizational requirements. (2) Due to the above-mentioned characteristics of spatial planning problems, we suggest using techniques of requirements engineering (RE) and CrowdRE for getting stakeholders (e.g. user groups) involved. (3) We propose video as a medium for communicating problems, solution alternatives, and arguments effectively within a mixed crowd of officials, citizens, children and elderly people.Although few spatial planning problems can be solved by software alone, this new perspective helps to focus discussions anyway. RE techniques can assist in finding common ground despite the heterogeneous group of stakeholders, e.g. citizens. Digital requirements and video are well-suited for facilitating distribution, feedback, and discourse via the internet. In this paper, we propose this new perspective as a timely opportunity for the spatial planning domain – and as an increasingly important application domain of CrowdRE.","PeriodicalId":382958,"journal":{"name":"2017 IEEE 25th International Requirements Engineering Conference Workshops (REW)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122203937","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}

Although there exist automated techniques that can classify user comments into various topics with high levels of precision, recent studies have shown that the top apps in the app stores do not have customer ratings that directly correlate with the app's success. This implies that no single requirements elicitation technique can cover the full depth required to produce a successful product and that applying alternative requirements gathering techniques can lead to success when these two are combined. Since user involvement has been found to be the most impactful contribution to project success, in this paper we will explore how the Wizard-of-Oz (WOz) technique and user reviews available in Google Play, can be integrated to produce a product that meets the demand of more stakeholders than either method alone. To compare the role of early interactive requirements specification and app reviews, we conducted two studies: (i) a case study analysis on 13 mobile app development teams who used very early stages Requirements Engineering (RE) by applying WOz, and (ii) a study analyzing 40 (70, 592 reviews) similar mobile apps on Google Play. The results of both studies show that while each of WOz and app review analysis techniques can be applied to capture specific types of requirements, an integrated process including both methods would eliminate the communication gap between users and developers at early stages of the development process and mitigates the risk of requirements change in later stages.","PeriodicalId":382958,"journal":{"name":"2017 IEEE 25th International Requirements Engineering Conference Workshops (REW)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124120077","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}
