Vorsitzender: Univ.-Prof. Dr. Helmut Seidl Prufer¨ der Dissertation: 1. Univ.-Prof. Bernd Brugge,¨ Ph.D. 2. Prof. Dr. Jurgen¨ Borstler,¨ Blekinge Institute of Technology, Karlskrona, Schweden Die Dissertation wurde am 28.01.2016 bei der Technischen Universitat¨ Munchen¨ eingereicht und durch die Fakultat¨ fur¨ Informatik am 29.02.2016 angenommen. Abstract Software is developed in increasingly dynamic environments. Organizations need the capability to deal with uncertainty and to react to unexpected changes in require- ments and technologies. Agile methods already improve the flexibility towards changes and with the emergence of continuous delivery, regular feedback loops have become possible. The abilities to maintain high code quality through reviews, to regularly re- lease software, and to collect and prioritize user feedback, are necessary for con- tinuous software engineering. However, there exists no uniform process model that handles the increasing number of reviews, releases and feedback reports. In this dissertation, we describe Rugby, a process model for continuous software en- gineering that is based on a meta model, which treats development activities as parallel workflows and which allows tailoring, customization and extension. Rugby includes a change model and treats changes as events that activate workflows. It integrates re- view management, release management, and feedback management as workflows. As a consequence, Rugby handles the increasing number of reviews, releases and feedback and at the same time decreases their size and effort.

  • Improving Software Development Through Combination of Scrum and Kanban
    Recent Advances in Computer Engineering, Communications and Information Technology Improving Software Development through Combination of Scrum and Kanban VILJAN MAHNIC Faculty of Computer and Information Science University of Ljubljana Trzaska 25, SI-1000 Ljubljana SLOVENIA [email protected] Abstract: - Applying Kanban principles to software development is becoming an important issue in the area of software engineering. The number of Scrumban users, a method that combines Scrum and Kanban practices, almost doubled in the last year. While Scrum is well-known and widespread method, scientific literature about Kanban adoption is scarce and many questions regarding Kanban use in practice (e.g., the structure of Kanban board, setting appropriate work in progress limits, combining Kanban and other agile methods, etc.) are still open. The aim of this paper is to upgrade previous research of different Kanban boards by proposing structure of a generic Kanban board and ground rules for its use, which could serve as a guiding reference for teams planning to introduce Scrumban as their development process. Additionally, an example of using such a board in practice is provided. The paper starts from the premise that appropriate combination of Scrum and Kanban advantages makes the most from both. Therefore, the proposed solution combines the most important Scrum practices (release and Sprint planning, regular delivery of increments, frequent feedback) with basic Kanban principles (visualization of workflow, limiting work in progress, change management). Key-Words: - Scrum, Kanban, agile methods, software development, software process management, quality improvement 1 Introduction According to the last State of Agile Development Numerous agile methods [1] have appeared in the Survey [9], the most widespread agile method is last fifteen years that – in contrast to traditional Scrum [10, 11].

Ett annat mål med avhandlingen var att studera bakgrunden till den agila metoden, hur den togs i bruk och hur den påverkar kundnöjdhet. I denna avhandling förklaras några existerande agila metoder, verktygen för hur agila metoder används, samt hur de påverkar programvaruutvecklingsteamet. Avhandlingen fokuserar sig på två agila metoder, Scrum och Kanban, eftersom de ofta används i olika företag. Ett av syftena med denna avhandling var att skapa förståelse för hur Scrumban metoden tas i bruk. Detta projekt granskar fördelarna med att ha ett mjukvaruutvecklingsteam som arbetar med agila processer. Projektet lyckades bra och en arbetsmiljö som använder agila metoder skapades. Fördelen blev att utvecklarteamet kunde göra förändringar när sådana behövdes.

    WHITE PAPER GETTING STARTED WITH CONTINUOUS INTEGRATION IN SOFTWARE DEVELOPMENT Amruta Kumbhar, Madhavi Shailaja & Ravi Shankar Anupindi Introduction DevOps culture is gaining rapid momentum in the IT industry as it enables business to adopt agile software delivery methodologies like Continuous Integration (henceforth referred to as CI) & Continuous Delivery (henceforth referred to as CD) .These methodologies enable quicker issue resolution, instant feedback loops, improved software quality and cost saving to meet the ever- increasing demand to deliver better software faster. It would not be wrong to say that CI-CD practices will soon become the de- facto software delivery standards across the industry. Though both these methodologies (CI and CD) This article compiles insights gained from complement each other, CI is the pre-requisite our practical experiences across various CI phase for enabling CD as the latter is built on enablement programs which we have been Gartner says “By 2016, top of the former.
