use case textual description template

use case textual description template

Thus, the Step Identifier structure, besides being the one with the best results in terms of time and accuracy, was also the favorite among the volunteers. 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. Home; About Us; Use Case Template and an Example. Table 8 presents a summary of the collected data. ISS conducted the experiment with the volunteers. Internal validity The experiment design was planned to minimize the effects of the threats to internal validity. (2006), named Research Type. In this paper, we report 1) guidelines to make use case descriptions amenable to textual analysis, 2) an … PASN conducted the result analysis and the hypothesis testing of the experiment. For agile development, a requirement model of many UML diagrams depicting use cases plus some textual descriptions, notes or use case briefs would be very lightweight and just enough for small or easy project use. It was firstly conducted between January and March 2014 (Santos et al. 2008; Jirapanthong 2009). 2013). The protocol is a plan that describes the conduct of a proposed SM study (Kitchenham and Charters 2007). (2003) and Gallina et al. (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. The SPL use cases’ comprehensibility was measured based on the subjects’ efficiency in understanding the SPL use cases used and performing the comprehension tasks. After removing duplicate studies, and reading title and abstract of all the 2394 papers according to Step 2, the result was a set of 101 potentially relevant studies. (2007) and Oliveira et al. This work is a partial result of the UbiStructure project supported by CNPq (MCT/CNPq 14/2011 - Universal) under grant number 481417/2011-7 and the Maximum project supported by FUNCAP (FAPs/INRIA/INS2i-CNRS 11/2011). Then, Gomaa (2004) proposed that these variations should be described at the end of the SPL use cases. http://doi.acm.org/10.1145/2648511.2648523. RQ3: Which variability types can be modeled in textual use cases of an SPL? m The final question was used to cut off the executions that had low quality. With the performed experiment we observed which characteristics of each use case template structure impact on the SPL use cases’ comprehensibility. Here are some of its characteristics: 1. Each unit has a specific role within the overall functionality of the system. In regards to the validity of the results, we discuss in the next paragraphs the internal and external validity. Erikssona, M, Borstler J, Borg K (2004) Marrying features and use cases for product line requirements modeling of embedded systems In: Proceedings of the Fourth Conference on Software Engineering Research and Practice in Sweden, 73–82.. Institute of Technology, Unitryck, Linköping University, Linköping, Sweden. (2009) identified approaches for the Variability Management in SPL and classified them with respect to historical background, the issues that motivated their creation, variability models used, and their support for the different SPL phases. As a result, the correct answer to the question is the letter b, which refers to a step mandatory of the use case (see step 1 in the Fig. 0 a Cheng, BHC, Atlee JM (2007) Research directions in requirements engineering In: Proceedings of the Future of Software Engineering (FOSE ’07).. IEEE Computer Society, Washington, DC, USA. 2004). Bragança, A, Machado RJ (2006) Extending uml 2.0 metamodel for complementary usages of the <> relationship within use case variability specification In: Proceedings of the 10th International on Software Product Line Conference, 123–130.. IEEE Computer Society, Washington, USA. Subject area: A use role or other grouping mechanism that can be used to group use cases. The results of the controlled experiment provide an empirical knowledge about the template structures identified, and this knowledge can help in the choice of a use case template for practical use, as well as in the execution of other controlled experiments with use cases. In Section 5, we describe the controlled experiment conducted with the SPL use case templates. c Note that the p-values for the Kolmogorov-Smirnov tests are near 0.000 (in the row “Asymp. https://sites.google.com/site/ismaylesantos/spl-use-case-experiment. The results for the time and accuracy variables are given in the Table 9 (for the group with the final question correct). 2004)). e According to Gomaa (2004), fine-grained variation could be specified in the SPL use cases with the following elements: name, type, line of the use case (the target of the variation), and description. For this purpose, there are several use case templates available in the literature to describe the functional requirements of an SPL. This tutorial briefs you about designing test cases with simple practical examples for our easy understanding. i A wrong answer in this question signaled a serious error in the use of the templates. Mustafa, BA (2010) An experimental comparison of use case models understanding by novice and high knowledge users In: Proceedings of the 2010 Conference on New Trends in Software Methodologies, Tools and Techniques, 182–199.. IOS Press, Amsterdam. c In the same scenario, Alves et al. No Highfalutin Theories! Finally, management is related directly to the control of the processes and activities, in order to allow the previous two activities to work together. Mandatory features are those available on all systems built within the family. Each tag is expanded in a section called “Variations” and is mapped to the Orthogonal Variability Model (OVM). Furthermore, these authors performed data extraction on a sample of the primary studies and their results were cross-checked with those of the first author. Figure 5 shows the “Withdraw Money” specified in this template. 2003) report a template that uses Tags to specify variability in the textual use case. A scenario is a list of steps. Use case diagrams are usually referred to as behavior diagrams used to describe a set of actions that some system or systems should or can perform in collaboration with one or more external users of the system . A requirement is a contract or promise that the use case will perform an action or … Alternatively a Use Cases may describe the interaction between two systems where no human is involved and in this case the Actor is the external system. Another distinguishing feature of this template is the use of local (with $) and global (with @) variables. However, we highlight that we monitored the volunteers during all the experiment in order to guarantee the concreteness of the registered time. Tiwari and Gupta (2013) conducted a controlled experiment to assess the usefulness of eight use case templates against a set of five judging criteria, namely completeness, consistency, understandability, redundancy, and fault proneness. 2003) described in Section 4.4.2. 2004). Typically it describes the use case goal and gives a general description of what usually happens, the normal course of events, adding a brief description of any minor variations. Zhou, J, Lu Y, Lundqvist K, Lonn H, Karlsson D, Liwang B (2014) Towards feature-oriented requirements validation for automotive systems In: Proceedings of the IEEE 22nd International Requirements Engineering Conference, 428–436.. IEEE Computer Society, Washington, DC, USA. A use caseis a description of how a person who actually uses that process or system will accomplish a goal. The keywords in this category are: Optional: The use case template supports the specification of optional steps; Mandatory alternative exactly 1: The use case template supports the specification of mutually exclusive alternatives for one mandatory step; Mandatory alternative at least 1: The use case template supports the specification of alternatives for one mandatory step out of which at least one must be selected; Optional alternative exactly 1: The use case template supports the specification of mutually exclusive alternatives for one optional step; Optional alternative at least 1: The use case template supports the specification of alternatives for one optional step out of which at least one must be selected. Blanes and Insfran (2012) analyzed requirement engineering approaches that use Model-Driven Development (MDD) techniques for SPL development. Benavides, D, Segura S, Ruiz-Cortés A (2010) Automated analysis of feature models 20 years later: A literature review. Regarding the mapping results, six studies (Bertolino and Gnesi 2003; Bragança and Machado 2005; Choi et al. : there is no statistically significant difference in terms of time required to understand the use cases’ behavior using the evaluated template structures. As Nguyen‘s template (Nguyen 2009) is based on Gomaa‘s template (Gomaa 2004), we chose the template from Gomaa. Identify the Key Components of Your Use Case. Neto, PAMS, Machado IC, Mcgregor JD, Almeida ES, Meira SRL (2011) A systematic mapping study of software product lines testing. Therefore, the controlled experiment was conducted with four use case templates representing four different structures to describe SPL variabilities in a use case. The most important model elements are: Use Cases, Actors; and the relationships between them. Tagged: usecase,case,uml,tech,software,use case mobile network,use case of cellular network,mobile phone use case,use case for mobile,use case template,usecase templates,use case,uml usecase. Although the system is usually automated (such as an Order system), use cases also apply … 2010; Jeyaraj and Sauter 2007; Mustafa 2010; Reinhartz-Berger and Sturm 2014). In this paper, we propose an abstract syntax for textual use case description as a meta-model extension of the UML Speci cation. The results showed that the approach is easy to use and useful for specifying the functional requirements in this particular SPL. (2014) conducted a controlled experiment that compared the comprehension of two models of a system and the quality of models created for a certain system with both OO-DFD and the Use Case. Table 1. In addition, we expect the same results for bigger use cases. The paper of Eriksson et al. We planned to minimize the effect of instrumentation by performing measures by a single person during the experiment. Requirements. Bertolino, A, Gnesi S (2004) Pluto: A test methodology for product families. View Template and example for a use case textual description.docx from SWEN 645 at University of Maryland, Baltimore. The comprehension tests were made in order to evaluate the comprehension related to each use case considered in the experimental study (in the same way as was done in (Mustafa 2010)). We have split the data set into two groups, since there are several participants who did not answer correctly the final question, avoiding the use of their data in these analyses. 2000) for hypothesis testing. Some project teams, such as those having … The order of these use cases in the tasks was fixed, as shown in Table 7. By means of this mapping it was possible to identify twelve textual use case templates that describe SPL variability and five different template structures for describing SPL variability in textual use cases: i) using tags; ii) with the step identifier of the use cases; iii) describing the variability in a specific section of the textual use case; iv) through alternative scenarios; and v) with advice use cases. The subjects using this template structure had better results in terms of accuracy; ERQ2: Which of the evaluated template structures requires less time to understand a use case? m Although some templates (Choi et al. For this, the participants registered the initial and final time for each comprehension task. Thus, observing that we have found templates that are recent, the specification of variability in textual use cases is still an interesting research topic. Oliveira, RP, Blanes D, Gonzalez-Huerta J, Insfran E, Abrahão S, Cohen S, Almeida ES (2014) Defining and validating a feature-driven requirements engineering approach. You can clarify the use case further by refining the use case into a formal use case or informal use case format (free template). In the meantime, it is possible to find empirical work with the templates identified in this SM, such as the ones from Alferez et al. The Systematic Mapping study is a type of secondary study that can complement Systematic Literature Reviews. Use Case Template - what is a Use Case in simple words is it’s a textual description of the interactions – presented as a flow of plain steps – between a role and a system, with the purpose of allowing the role to accomplish a certain goal. Description: A brief textual description of what the use case does. (2005) were selected to the experiment because they are unique with their structures (Alternative Scenario and Step Identifer). The order of template used was totally random. 2008), and after that, they describe an approach for use case scenario variability management (Bonifácio and Borba 2009). For additional details please refer to our previous work (Santos et al. For this mapping study, we defined just one inclusion criterion: (IC1) the study presents a template for textual use cases description of an SPL. For this, works in literature (e.g. We also identified some studies addressing the assessment of the understanding of the requirements provided by the use cases in software development (Dahan et al. and Is there another identification type?) (2003) and Choi et al. a use case instance • use case - a collection of related success and failure scenarios, describing actors … Five of the templates were not classified in this category because they do not specify explicitly the type of variability in the use cases description. Innov Syst Softw Eng 8: 51–64. (2014) summarized existing research related to variability handling in software systems and proposed the classification for variability in different dimensions. The example I provided uses a very simple format. Then, in spite of the fact that this study has a specific focus (textual use case templates) we chose the Systematic Mapping approach because the main goal of this study is to identify and classify the different SPL use case templates. Section 3 presents the proposed template for textual description of use cases for CASPL and the preliminary evaluation of this template. Considering only the valid executions, the Specific Section structure had a preference of 29.1% of the experiment volunteers and the Tags structure had a preference of 21.6%. We can see in Table 5 that the Tags structure has the largest number of templates. Flow of events Wieringa, R, Maiden N, Mead N, Rolland C (2006) Requirements engineering paper classification and evaluation criteria: a proposal and a discussion. Note that there are additional elements to a formal use case that may be included, but are not part of this example. : Extending telelogic doors and ibm-rational rose to support product line use case modeling In: Proceedings of the 20th IEEE/ACM International Conference on Automated Software Engineering, 300–304.. ACM, New York, NY, USA. Make sure you store use cases so that they are easily found, edited, and used. Requir Eng J 19: 355–376. 2014)) adapted these artifacts in order to incorporate the SPL variability. 2003; Gallina and Guelfi 2007; Choi et al. In this scenario, Bonifacio and Borba (2008) show that the use of the PLUC (Bertolino and Gnesi 2003) could result in maintainability issues because introducing a new product variant might require changes in several artifacts. This tutorial explains how to create a detailed Use Case Template Text. Example of use case with Specific Section. Templates for textual use cases of software product lines: results from a systematic mapping study and a controlled experiment, http://www.great.ufc.br/index.php/en.html, ftp://ftp.software.ibm.com/software/rational/web/whitepapers/2003/TP165.pdf, http://www-01.ibm.com/software/analytics/spss/, http://www.sei.cmu.edu/productlines/frame_report/, https://sites.google.com/site/ismaylesantos/spl-use-case-experiment, http://doi.acm.org/10.1145/2648511.2648523, https://creativecommons.org/licenses/by/4.0, https://doi.org/10.1186/s40411-015-0020-3, SBCARS 2014 (Brazilian Symposium on Software Components, Architectures and Reuse). In terms of participants’ preference, it was also the favorite, as indicated by 46.3% of volunteers. Teams constructing from commercial, off-the-shelf components (COTS) use this description in selecting the components. 4.a.1 System lets user know that album already exists. 19: 32–40. The accuracy from the use of these structures indicated a statistically significant difference (better) when compared to the Advice Use Case structure. In the Choi et al. In the third step, we read the full paper and selected those which have a textual use case template for an SPL with a focus on describing SPL variabilities within the use cases description. In this section, the variation type, a brief description and the use case steps that are affected by the variation are specified; Step identifier: The use case template uses the step identifier of the use case to describe variants in use case scenarios; Advice use case: The use case template describes the variabilities as advice use cases. Overview Information 2. 2008). Only two graduate students had never worked with textual use case descriptions while eight graduate students had never studied SPL. 6) aiming to generate a quick overview of the evidence gathered from this SM. 1 INTRODUCTION The Uni ed Modeling Language (UML) de nes a use case as \the speci cation of a … The authors declare that they have no competing interests. We have used the Kruskal Wallis test (Hollander and Wolfe 1999; Wohlin et al. That is, it specifies how a user interacts with a system and how the system responds to the user actions. In this section we present the controlled experiment conducted with the template structures found in the literature for textual specification of SPL use cases. 2011). The work of Bonifacio and Borba (2009) was also classified as Validation Research, because they present four case studies comparing their proposal with the PLUS approach (Eriksson et al. Tiwari, S, Gupta A (2013) A controlled experiment to assess the effectiveness of eight use case templates In: 20th Asia-Pacific Software Engineering Conference, vol. Take a Quick Tour of Visual Use Case (Flash movie, 1MB) To save these files, right click on the link and choose 'Save Target As'. Even if you aren’t a business analyst, you can benefit from writing use cases: As a business user, if you can write a use case that describes what a piece of software does or needs to do, you’ll know enough … (2007), which reports an experimental case study constructing an SPL with the PLUS method (Gomaa 2004). Our Systematic Mapping also addresses the variability modelling, but with focus on the specification of the variability in the user’s perspective through the textual use cases. 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. For this, the authors have described the four use cases in each template selected for the experiment. RQ2: How could SPL variability be modeled in textual use cases? The detailed use case is a textual representation illustrating a sequence of events together with other related use case information in certain format. (2014) present a case study with their approach. Kuloor, C, Eberlein A (2002) Requirements engineering for software product lines In: Proceedings of the International Conference Software Systems Engineering and Their Applications.. CNAM - Conservatoire National des Arts et Métiers, Paris, France. The four use cases used in the study are similar in terms of complexity and size. This implies that the data set is not normal because the p-value was smaller than the significance level (alpha) 0.05. By conducting an SM that involves a controlled and formal literature search, we believe that the results of this paper will benefit researchers and practitioners. According to Northrop (2002), an SPL is “a set of software-intensive systems that shares a common managed feature set, satisfying a particular market segment‘s specific needs or mission and that is developed from a common set of core assets in a prescribed way”. (2014) evaluated their requirements engineering approach, the Feature-Driven Requirements Engineering approach (FeDRE), through a case study for developing an SPL of mobile applications for emergency notifications. 2000), a non-parametric method, for testing whether samples originate from the same distribution (an alternative for one-way ANOVA). Input compris-es of textual use-cases and Temporal Annotation De nition Language (TADL) templates. Jirapanthong, W (2009) Analysis on relationships among software models through traceability activity In: Proceedings of the 3rd International Conference on Advances in Information Technology (IAIT).. Springer-Verlag, Berlin, Heidelberg. In this approach, the variabilities can be modeled by advice use cases that extend the behavior of base use cases. (2011), which is divided into three main phases: Research Directives, Data Collection, and Results. This explains the actors, conditions – pre & post, flow of events ,alternative flows , exceptional flow and other important information of a use case. Use Case diagram for Uber service. Table 10 presents the results of the hypothesis testing performed in order to compare the results related to time to complete the experiment tasks and the accuracy of the task execution. Gallina and Guelfi (2007) propose a Use Case Elicitation Template (UCET) that provides special fields to collect information concerning variabilities: a) selection category, which specifies whether the use case is mandatory, optional or alternative; b) a description of variation points, and c) fault variation description, used to describe the faults strongly related to the variation points.

The use case template identified in the Bragança and Machado‘s paper (Bragança and Machado 2005) specifies the variation points through OPT and ALT tags. The category Research Type was proposed by Wieringa et al. (2007)), with specific elements to deal with the variabilities and commonalities of an SPL. Subjects who selected the Step Identifier structure as the best structure, for example, reported that it has a simple description and an objective, clean, organized, and compact structure. [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. Finally, Section 5 concludes the paper and presents future directions. Furthermore, the examples used in the experiment have a low level of crosscutting features and this may have affected the results related to this structure, since the main advantage of this structure is in specifying crosscutting features. The actual use case is a textual representation illustrating a sequence of events. (2010) and Dahan et al. Eriksson, M, Börstler J, Borg K (2005) The pluss approach: domain modeling with features, use cases and use case realizations In: Proceedings of the 9th International Conference on Software Product Lines (SPLC’05), 33–44.. Springer-Verlag, Berlin, Heidelberg. Use case descriptions. We did this to avoid the compensatory equalization of treatments, compensatory rivalry, and resentful demoralization (Wohlin et al. a Use Case Template for Financial Trading System. Bonifácio, R, Borba P (2009) Modeling scenario variability as crosscutting mechanisms In: Proceedings of the 8th ACM International Conference on Aspect-oriented Software Development, 125–136.. ACM, New York, NY, USA. Forty eight (48) volunteers participated in the study. 11 - Product Line Use Cases: Scenario - Based Specification and Testing of Requirements. 1st edn. So, it is possible that, with the feature model, this structure had better results, because the approach of Bonifacio and Borba (2009) is defined as a composition of different artifacts: use cases model, feature model, product configuration, and configuration knowledge. 2014). Below is a use case diagram template of a financial trading system. As we can see in this figure, steps 2 and 3 are optional ones.
