Writing and Reviewing Use-Case Descriptions
Bittner/Spence_06.fm Page 145 Tuesday, July 30, 2002 12:04 PM PART II WRITING AND REVIEWING USE-CASE DESCRIPTIONS Part I, Getting Started with Use-Case Modeling, introduced the basic con- cepts of use-case modeling, including defining the basic concepts and understanding how to use these concepts to define the vision, find actors and use cases, and to define the basic concepts the system will use. If we go no further, we have an overview of what the system will do, an under- standing of the stakeholders of the system, and an understanding of the ways the system provides value to those stakeholders. What we do not have, if we stop at this point, is an understanding of exactly what the system does. In short, we lack the details needed to actually develop and test the system. Some people, having only come this far, wonder what use-case model- ing is all about and question its value. If one only comes this far with use- case modeling, we are forced to agree; the real value of use-case modeling comes from the descriptions of the interactions of the actors and the system, and from the descriptions of what the system does in response to the actions of the actors. Surprisingly, and disappointingly, many teams stop after developing little more than simple outlines for their use cases and consider themselves done. These same teams encounter problems because their use cases are vague and lack detail, so they blame the use-case approach for having let them down. The failing in these cases is not with the approach, but with its application. -
Metamodeling Variability to Enable Requirements Reuse
Metamodeling Variability to Enable Requirements Reuse Begoña Moros 1, Cristina Vicente-Chicote 2, Ambrosio Toval 1 1Departamento de Informática y Sistemas Universidad de Murcia, 30100 Espinardo (Murcia), Spain {bmoros, atoval}@um.es 2 Departamento de Tecnologías de la Información y las Comunicaciones Universidad Politécnica de Cartagena, 30202 Cartagena (Murcia), Spain [email protected] Abstract. Model-Driven Software Development (MDSD) is recognized as a very promising approach to deal with software complexity. The Requirements Engineering community should be aware and take part of the Model-Driven revolution, enabling and promoting the integration of requirements into the MDSD life-cycle. As a first step to reach that goal, this paper proposes REMM, a Requirements Engineering MetaModel, which provides variability modeling mechanisms to enable requirements reuse. In addition, this paper also presents the REMM-Studio graphical requirements modeling tool, aimed at easing the definition of complex requirements models. This tool enables the specification of (1) catalogs of reusable requirements models (modeling for reuse facet of the tool), and (2) specific product requirements by reusing previously defined requirements models (modeling by reuse facet of the tool). Keywords: Model-Driven Software Development (MDSD), Requirements Engineering (RE), Requirements MetaModel (REMM), Requirements Reuse, Requirements Variability. 1 Introduction Model-Driven Software Development (MDSD) aims at raising the level of abstraction at which software is conceived, implemented, and evolved, in order to help managing the inherent complexity of modern software-based systems. As recently stated in a Forrester Research Inc. study “model-driven development will play a key role in the future of software development; it is a promising technique for helping application development managers address growing business complexity and demand ” [1]. -

It has brought challenges to organizations in adopting the existing traditional methods, as well as new ones. Design Thinking has been used as a requirements elicitation technique and immersion in the process areas, which brings the client closer to the software project team and enables the creation of better projects. With the use of data triangulation, this paper brings a literature review that collected the challenges in software requirements elicitation in agile methodologies and the use of Design Thinking. The result gave way to a case study in a Brazilian public organization project, via user workshop questionnaire with 20 items, applied during the study, in order to identify the practice of Design Thinking in this context. -

It allows both on and offshore team to work in small iterations minimizing the effect of change in software requirements and at the same time developing regular communication between them. However different factors such as physical distance and lack of communication between on and offshore team becomes a hurdle between them leading to misunderstandings about software requirements. This research work gives an insight about these challenges from the software industry by presenting and discussing the responses of four software companies located in different countries, collected through an online questionnaire. -

Tools for Requirements Management in GSD: a Survey Muhammad Mukhtar, Zishan Hussain Chuhan, Zulfiqar Ahmad
International Journal of Scientific & Engineering Research, Volume 6, Issue 4, April-2015 1935 ISSN 2229-5518 Tools for Requirements Management in GSD: A Survey Muhammad Mukhtar, Zishan Hussain Chuhan, Zulfiqar Ahmad Abstract--- The software requirement specification (SRS) is a volatile document. Even well documented SRS evolves and grows throughout Software Development Life Cycle. Requirements management plays an important role to manage evolution and growth in SRS. Managing requirements in manual ways becomes very difficult especially in global software development due to some additional factors (time zone difference, cultural issues, geographical boundaries, etc.). To overcome this difficulty software industry moves to automate the requirements management. In this research activity, our focus is to survey about tools to automate the requirements management in global software development (GSD). We consider existing tools in this survey those are not developed for GSD and evaluate them on defined parameters in the context of GSD. In short our goal is to validate the existing tools for GSD. Index Terms - Requirements Management, SRS, Tools, Automation, GSD, Integration, Access Control —————————— —————————— 1 Introduction develop many tools These tools proved to be very Requirements management (RM) is a helpful to keep specifications consistent, up-to-date, discipline, in which change and versions of ensure requirements traceability and accessible [3, requirement is controlled, update plan according to 9]. In fact, the existing tools (DOORS, Analyst Pro, the current requirements, managing traceability of PACE, etc) were not developed for global software requirements (impact analysis), and status of the development. Existing requirements management requirements is tracked [1]. SRS is a volatile and tools require a high degree of knowledge to dynamic document because requirements are understand and use it [5].
