Such teams often use online tools such as mailing lists, bug tracking systems or online discussion forums to communicate, clarify or coordinate work on requirements. In this kind of environment, the expected evolution from initial idea, through clarification, to a stable requirement, often stagnates. When project managers are not aware of underlying problems, development may proceed before requirements are fully understood and stabilized, leading to numerous implementation issues and often resulting in the need for early redesign and modification. In this paper, we present an approach to analyzing online requirements communication and a method for the detection and classification of clarification events in requirement discussions. We used our approach to analyze online requirements communication in the IBM® Rational Team Concert® (RTC) project and identified a set of six clarification patterns. Since a predominant amount of clarifications through the lifetime of a requirement is often indicative of problematic requirements, our approach lends support to project managers to assess, in real-time, the state of discussions around a requirement and promptly react to requirements problems.","PeriodicalId":137833,"journal":{"name":"2012 20th IEEE International Requirements Engineering Conference (RE)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117271753","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}

Companies that produce a number of partially similar products can reduce development time and cost, improve quality and simplify software maintenance by applying reuse practices. Requirements reuse is an essential enabler to achieve effective software reuse. This study describes two different approaches for requirements reuse at Danfoss. The first approach reuses those requirements that are envisioned to be common between two consecutive projects and allows changing and parameterization of parts of the requirements. The second approach organizes all requirements into a common model and explicitly manages variability and different requirement variants in this common model. The results show that both approaches can result in significant savings in reduced effort by reusing common requirements. The first approach was found to be effective when the domain maturity is low and the significant set of requirements were changed from project to project. The second approach allows high reuse potential and significant savings for stable domains, where most requirements tend to be small additions or minor changes of existing requirements.","PeriodicalId":137833,"journal":{"name":"2012 20th IEEE International Requirements Engineering Conference (RE)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122140109","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}

Due to the intrinsic vagueness of speculative language, speculative requirements risk being misunderstood, and related uncertainty overlooked, and may benefit from careful treatment in the requirements engineering process. In this paper, we present a linguistically-oriented approach to automatic detection of uncertainty in natural language (NL) requirements. Our approach comprises two stages. First we identify speculative sentences by applying a machine learning algorithm called Conditional Random Fields (CRFs) to identify uncertainty cues. The algorithm exploits a rich set of lexical and syntactic features extracted from requirements sentences. Second, we try to determine the scope of uncertainty. We use a rule-based approach that draws on a set of hand-crafted linguistic heuristics to determine the uncertainty scope with the help of dependency structures present in the sentence parse tree. We report on a series of experiments we conducted to evaluate the performance and usefulness of our system.","PeriodicalId":137833,"journal":{"name":"2012 20th IEEE International Requirements Engineering Conference (RE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127696281","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}

Software engineers have to go through the whole requirements document and look for the requirements that are affected by a change. Consequently, engineers usually apply changes to the implementation directly and leave requirements unchanged. In this paper, we propose an approach for automatically detecting outdated requirements based on changes in the code. Our approach first identifies the changes in the code that are likely to affect requirements. Then it extracts a set of keywords describing the changes. These keywords are traced to the requirements specification, using an existing automated traceability tool, to identify affected requirements. Automatically identifying outdated requirements reduces the effort and time needed for the maintenance of requirements specifications significantly and thus helps preserve the knowledge contained in them. We evaluated our approach in a case study where we analyzed two consecutive source code versions and were able to detect 12 requirements-related changes out of 14 with a precision of 79%. Then we traced a set of keywords we extracted from these changes to the requirements specification. In comparison to simply tracing changed classes to requirements, we got better results in most cases.","PeriodicalId":137833,"journal":{"name":"2012 20th IEEE International Requirements Engineering Conference (RE)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133535845","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}
