    Användning av prototyper som verktyg för kravhantering i agil mjukvaruutveckling: - En fallstudie2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Requirements Engineering (RE) in Agile Software Development (ASD) is a challenge thatmany face and several techniques exist when doing so. One such technique is prototyping, when a model of a product is used to gather important information in software develop-ment. To describe how much a prototype resembles the product the notion of fidelity is used. The aim of this study is to contribute to research regarding prototyping in ASD,and to examine the effect of a prototype’s fidelity when using prototypes in discussionsduring RE. A case study is performed at the company Exsitec where staff are interviewedregarding prototyping in software development. Thereafter, two prototypes of low andhigh fidelity are developed and used in interviews as a basis for discussion. Based on thisstudy, the use of prototypes in software projects can help customers trust the process,improve communication with customers, and facilitate when trying to reach consensusamong different stakeholders. Furthermore, depending on how they are used, prototypescan contribute to understanding the big picture of the requirements and can also serve asdocumentation. The study also shows some, albeit subtle, differences in the informationcollected using prototypes with low and high fidelity. The use of a high fidelity prototypeseems to generate more requirements, but makes interviewees less likely to come up withlarger, more comprehensive requirement changes.

    Implementering av en användbar e-butik för tygmärken: En praktisk fallstudie av webbapplikationen Festing2016Independent thesis Basic level (degree of Bachelor), 12 credits / 18 HE creditsStudent thesis
    Abstract [en]

    This report covers the development of the web application Festing and the results and experiences which have been reached and learned during the process. The purpose of the study was to examine how the selling of patches could be both simplified and improved by using an advanced web application designed with focus on usability. Currently the patches are sold in a large but geographically and temporally limited market at Linköping University. The project was comprised of a case study and development of an application following the agile project framework Scrum. According to this the projects has been split up into four sprints after each of which a working product was delivered. This resulted in a usable web application with an intuitive design and multiple functions linked to the selling and buying of patches. Based on interviews, surveys and usability tests this web application is considered to have the long-term potential to take over the current physical market of textile patches.
