Therefore, approaches to describe variability based on include/extend relationships (e.g. Guidance for Use Case Template. Santos, I.S., Andrade, R.M. In a recent post, I … The Use Case Specification is represented in the Use Case Diagram by an oval, and is what most … Formal Use Case Example. On the other hand, the Solution Proposal, which is a non-empirical research category, is the topic with more entries (9 papers - 73%). The second phase, Data Collection, comprises the execution of the Systematic Mapping, during which the search for the primary studies is performed and the inclusion/exclusion criteria are used in order to select relevant studies according to the research questions. From this mapping, we found twelve SPL use case templates and observed the need not only for the application of these templates in real SPL but also for supporting tools. Petersen, K, Feldt R, Mujtaba S, Mattsson M (2008) Systematic mapping studies in software engineering In: Proceedings of the 12th International Conference on Evaluation and Assessment in Software Engineering, 68–77.. British Computer Society, Swinton, UK, UK. Azevedo, S, Machado RJ, Bragança A, Ribeiro H (2012) On the refinement of use case models with variability support. BA Workshop; About our Instructors; About … 2005). Use Case Templates Use case specifications tend to be written in a standardized form, and over the years a number of use case specification templates have been created including the one you can download from here. • Used here: Use case, class, object, statechart, sequence, collaboration, and activity diagrams • Development of the case study also demonstrates a typical development process • Diagram order in this document does not reflect the order occurring in the development. 6) aiming to generate a quick overview of the evidence gathered from this SM. Use Case Template for Financial Trading System. However, to the best of our knowledge, no efforts have been made to collect and summarize these existing templates. The work of Alferez et al. These databases are listed in Table 1 and were selected because we agree with (Morelli and Nakagawa 2011; Souza et al. Nguyen (2009) extends Gomaa‘s template (Gomaa 2004) to specify non-functional requirements. A scenario is a list of steps. 0 t In the SPL paradigm, the requirements engineering activity needs to cope with common and variable requirements for the whole set of products in the family (Oliveira et al. Within this category, six studies (Bertolino and Gnesi 2003; Bragança and Machado 2005; Choi et al. However, to the best of our knowledge, there has not been a systematic effort to collect and summarize the existing templates for textual use case descriptions in the SPL paradigm and there is no empirical assessment of the SPL use cases’ comprehensibility provided by these use case templates. In domain engineering, the requirements of the domain must be defined as common and variable requirements. There are specific branches of business use case such as business analyst use case, business specification, business processes and more. These advice use cases are defined in the same way as normal use cases, but they may only have some of the use case sections. Each step needs to be … On the other hand, the alternative variants are described through the tags and . This new paper extends on that work by: Updating the systematic mapping in order to consider papers published in 2014; Including papers with an aspect-oriented approach for SPL use cases modelling; Presenting a controlled experiment, following the guide of Wohlin et al. The overall goal of this investigation was to evaluate, with respect to effort, from the point of view of the researcher, in the context of Computer Science students and developers, the effect of the use case templates structures on the SPL use cases’ comprehensibility. Inf Syst 35(6): 615–636. Neiva (2009) investigated which RE activities are adopted, which models and techniques are used, and how the approaches for RE in SPL deal with variability. Figure 1 presents the use case “Withdraw Money” in the template found in the Bragança and Machado work (Bragança and Machado 2005). The dependent variables (representing the output or effect) were the accuracy and time spent with respect to comprehension tests used to measure the comprehensibility provided by the use case template structures. The requirements define the formal functional requirements that a use case must supply to the end user. 2014)) adapted these artifacts in order to incorporate the SPL variability. Alternative features represent a selection “exactly-one-of-many” made from a set of features. [Free Use Case Template] As a business analyst, use cases will help you ask incredibly smart questions about the software, even when you don’t actually know that much about the technology or the business. For those who like to read instead of watch, here’s the full text of the video: ... It’s a textual description that captures the user system interaction. When tags (e.g. 2003) present the Tags structure to deal with the SPL variabilities, while only two papers (Nguyen 2009; Gomaa 2004) have used the Specific Section structure and one (Anthonysamy and Somé 2008) has used Advice Use Case. In Software Product Line development, the requirements engineering activity needs to cope with common and variable requirements for the whole set of products in the family. Using Creately editor, you can change these colors as you wish. Both present a use case example with the template proposed by Bertolino and Gnesi (2003). © 2020 Springer Nature Switzerland AG. (2014) summarized existing research related to variability handling in software systems and proposed the classification for variability in different dimensions. Nguyen, QL (2009) Non-functional requirements analysis modeling for software product lines In: Proceedings of the ICSE Workshop on Modeling in Software Engineering (MISE ’09).. IEEE Computer Society, Washington, DC, USA. Use case analysis usually starts by drawing use case diagrams. Besides the two defined categories, we decided to use the category for classification of research defined by Wieringa et al. For this comparison, they used five criteria: SPL activity support, RE covered tasks, MDD strategy support, the degree of automatic support with a given tool, and the type of validation of the proposals. This comparison was made based on the SPL requirements modeling, specification, verification and management. 2011). The main purpose of the use case specification is to specify any pre-conditions that must be met in order to start the use case, specify any business rules related to the … Part of Springer Nature. Moreover, most of the templates were published in international conferences and one of the templates was found in a book. Business Use Case Templates – A business use case is one of the widely used type of use case. An effective Use Case should provide a detailed step-by-step description of how the system will be used by its actors to achieve the planned outcome. In terms of participants’ preference, it was also the favorite, as indicated by 46.3% of volunteers. However, in the template found in (Bragança and Machado 2005), the variability indicated by the tags is described in the main scenario. Template for a use case textual description: Example of a use case textual description, using the above template: The Create Album feature allows the user of the software to create a new album in. (2008) propose a simpler tag notation than Bertolino and Gnesi (2003). Technical report, Software Engineering Institute, Carnegie Mellon University. It was firstly conducted between January and March 2014 (Santos et al. Yu et al. However, it is not enough to only manage variability among whole use cases; it must also be possible to specify variant behavior within use case descriptions (Erikssona et al. Maybe, the difference among the two approaches that got statistically equals results could change, showing that one approach is better than other in this context. (2006), named Research Type. (2014)) presents a metric-based evaluation aimed at assessing quality attributes such as modularity, stability and expressiveness of SPL requirements approaches like the PLUSS (Eriksson et al. to implement this use case. Hollander, M, Wolfe DA (1999) Nonparametric Statistical Methods. Kuloor and Eberlein (2002) described and compared requirements engineering techniques used in existing SPL practices. Description: A brief textual description of what the use case does. From these, the newest paper (Alferez et al. PubMed Google Scholar. 6.1 Getting Started 219 Overview on the Used Development Process (1) Start with a use case diagram giving an overview on the system, its … Finally, with regards to the textual description of use cases, the use case template from Cockburn (2000) has inspired the creation of SPL use case templates (e.g.
