The closed set-up of systems and information is replaced by wide access to data of users and competitor products. This shift offers completely new opportunities to approach requirements elicitation and subsequent planning of software functionality. This is, in particular true for app store markets. App stores are markets for many small sized software products which provide an open platform for users to provide feedback on using apps. Moreover, the functionality and status of similar software products can be retrieved. While this is a competitive risk, it is at the same time an opportunity.In this paper, we envision a new release planning approach that leverages the new opportunities for decision making. We propose a new model using bi-criterion integer programming. We make suggestions for optimized super app functionality that are based on two key aspects: (i) the estimated value of features, and (ii) the cohesiveness between newly added features and cohesiveness between existing and the features to be added. The information on these attributes comes from reasoning on feature composition of existing similar apps. The approach is applicable to the development of new product releases as well as to the creation of completely new apps. We illustrate the applicability of our model by a small example and outline directions for future research.","PeriodicalId":176958,"journal":{"name":"2017 IEEE 25th International Requirements Engineering Conference (RE)","volume":"36 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120903260","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}

Maalej","doi":"10.1109/RE.2017.71","DOIUrl":"https://doi.org/10.1109/RE.2017.71","url":null,"abstract":"A main advantage of app stores is that they aggregate important information created by both developers and users. In the app store product pages, developers usually describe and maintain the features of their apps. In the app reviews, users comment these features. Recent studies focused on mining app features either as described by developers or as reviewed by users. However, extracting and matching the features from the app descriptions and the reviews is essential to bear the app store advantages, e.g. allowing analysts to identify which app features are actually being reviewed and which are not. In this paper, we propose SAFE, a novel uniform approach to extract app features from the single app pages, the single reviews and to match them. We manually build 18 part-of-speech patterns and 5 sentence patterns that are frequently used in text referring to app features. We then apply these patterns with several text pre-and post-processing steps. A major advantage of our approach is that it does not require large training and configuration data. To evaluate its accuracy, we manually extracted the features mentioned in the pages and reviews of 10 apps. The extraction precision and recall outperformed two state-of-the-art approaches. For well-maintained app pages such as for Google Drive our approach has a precision of 87% and on average 56% for 10 evaluated apps. SAFE also matches 87% of the features extracted from user reviews to those extracted from the app descriptions.","PeriodicalId":176958,"journal":{"name":"2017 IEEE 25th International Requirements Engineering Conference (RE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114621831","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}

Moura","doi":"10.1109/RE.2017.52","DOIUrl":"https://doi.org/10.1109/RE.2017.52","url":null,"abstract":"As software changes, it may become more difficult to under-stand, to be changed and harder to be reusable. In such cases, reengineering is a well-suited approach. While reengineering a system for renovation and reclamation, an organization gener-ally reassesses how the system implements high-level business requirements and makes modifications to conform to desired changes. Reengineering usually involves some form of reverse engineering to achieve a more abstract description of the soft-ware. We consider that a self-adaptive system implements awareness requirements, a high-level abstraction for self-adaptation. Awareness requirements are nonfunctional re-quirements (NFRs) about the software environment, as well as about the software itself (i.e.: the ability to perceive what is hap-pening about itself) for management and/or adaptation purpos-es. Most of the effort on self-adaptive system reengineering is focused on separation of concerns (i.e.: adaptation logic and application logic) or evolve a non-adaptive to a self-adaptive system. We identified that the design recovery approaches being used, limit themselves to recover the application logic, thus leav-ing the adaptation logic in low-level models. This fact leads to lack of proper integration at high-level models, resulting in im-plementation problems. Our research aims to tackle these prob-lems, by using the concept of awareness requirements as soft-goal in a goal-oriented model. We understand that recovering the adaptation operationalization and mapping them onto an i* based goal model will provide a high-level description of both the adaptation logic as well as the application logic.","PeriodicalId":176958,"journal":{"name":"2017 IEEE 25th International Requirements Engineering Conference (RE)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114791777","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}

To accomplish these tasks, a Requirements Engineer or Business Analyst needs to retrieve and combine information from multiple sources such as use case models, interview scripts, and business rules. However, collecting and analyzing all the required data can be tedious and the resulting data is often incomplete with inadequate trace links. Analyzing real-world queries can shed light on the questions requirements professionals would like to ask and the artifacts needed to support such questions. We therefore conducted an online survey with requirements professionals in the IT industry. Our analysis included 29 survey responses and a total of 159 natural language queries. Using open coding and grounded theory, we analyzed and grouped these queries into 9 different query purposes and 54 sub-purposes, and also identified frequently used artifacts. The results from the survey could help project-level planners identify important questions, proactively instrument their environments with supporting tools, and strategically collect data that is needed to answer the queries of interest to their project.","PeriodicalId":176958,"journal":{"name":"2017 IEEE 25th International Requirements Engineering Conference (RE)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121785586","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}

Within these cyber-physical system-networks, behavior emerges from the interplay of the connected systems that cannot be attributed to a single system. Verifying single system behavior as well as the resulting emergent behavior of the system-network the single systems contribute to, is challenging as the intended behavior differs between the different cyber-physical system-networks the single system takes part in. It can even differ between two almost identical cyber-physical system-networks, which, for example, only differ by one system. To ensure correct behavior, requirements engineering for cyber-physical systems must cope with the identification and documentation of the cyber-physical system's dynamic context, i.e. the different system-networks the system takes part in (e.g., a system-network of vehicles forming a platoon on a highway) as well as the context situations these system-networks can encounter (e.g., road work leading to the need for lane shifts). This paper contributes a solution idea for automated support in identifying relevant system-networks the system will have to interact with and for verifying the cyber-physical system under development against these relevant system-networks.","PeriodicalId":176958,"journal":{"name":"2017 IEEE 25th International Requirements Engineering Conference (RE)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115910720","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}

Of course, such goals, like anything else, may change over time. In earlier work, we introduced Evolving Intentions: an approach that allows stakeholders to specify how evaluations of goal model elements change over time. Simulation over Evolving Intentions enables stakeholders to ask a variety of 'what if' questions, and evaluate possible evolutions of a goal model. GrowingLeaf is a web-based tool that implements both the modeling and analysis components of this approach. In this paper, we investigate the effectiveness and usability of Evolving Intentions, Simulation over Evolving Intentions, and GrowingLeaf. We report on a between-subjects experiment we conducted with fifteen graduate students familiar with requirements engineering. Using qualitative, quantitative, and timing data, we show that Evolving Intentions were intuitive, that Simulation over Evolving Intentions increased the subjects' understanding and produced meaningful results, and that GrowingLeaf was found to be effective and usable.","PeriodicalId":176958,"journal":{"name":"2017 IEEE 25th International Requirements Engineering Conference (RE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131358573","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}

In security, for example, this can result in weak security constraints that are too general, or missing constraints. Another challenge is that analysts are unclear on where to stop generating new scenarios. In this paper, we introduce the Multifactor Quality Method (MQM) to help requirements analysts to empirically collect system constraints in scenarios based on elicited expert preferences. The method combines quantitative statistical analysis to measure system quality with qualitative coding to extract new requirements. The method is bootstrapped with minimal analyst expertise in the domain affected by the quality area, and then guides an analyst toward selecting expert-recommended requirements to monotonically increase system quality. We report the results of applying the method to security. This include 550 requirements elicited from 69 security experts during a bootstrapping stage, and subsequent evaluation of these results in a verification stage with 45 security experts to measure the overall improvement of the new requirements. Security experts in our studies have an average of 10 years of experience. Our results show that using our method, we detect an increase in the security quality ratings collected in the verification stage. Finally, we discuss how our proposed method helps to improve security requirements elicitation, analysis, and measurement.","PeriodicalId":176958,"journal":{"name":"2017 IEEE 25th International Requirements Engineering Conference (RE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130446078","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}

The popular prioritization techniques assume that stakeholders are known and can be mandated to contribute to the prioritization process. This prerequisite no longer holds for many of today's systems where significant stakeholders (end-users, in particular) are outside organizational reach: they are neither known nor can they be identified among the members of the involved organizations. Classic techniques for involving these stakeholders such as polls or questionnaires are neither interactive nor collaborative, which is detrimental for prioritization. Social media enable collaborative prioritization, but fall short in motivating stakeholders outside organizational reach to participate voluntarily. In this light, we are developing the Garuso platform, which combines social media with gamification for motivating stakeholders. While first approaches to employing gamification in RE are promising, research is still in its infancy. Especially, little is known about the influence of the gamification algorithms controlling single game elements on the stakeholders' activities. In this paper we report on a field experiment in which we investigated this influence with Garuso. We found statistically significant differences between different algorithms controlling single game elements on the contributions of stakeholders to the prioritization of requirements.","PeriodicalId":176958,"journal":{"name":"2017 IEEE 25th International Requirements Engineering Conference (RE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116032125","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}
