  • 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].

  • Agile Software Development and Im- Plementation of Scrumban
    Joachim Grotenfelt Agile Software Development and Im- plementation of Scrumban Metropolia University of Applied Sciences Bachelor of Engineering Mobile Solutions Bachelor’s Thesis 30 May 2021 Abstrakt Författare Joachim Grotenfelt Titel Agile software utveckling och Implementation av Scrumban Antal Sidor 31 sidor Datum 30.05.2021 Grad Igenjör YH Utbildningsprogram Mobile Solutions Huvudämne Informations- och kommunikationsteknologi Instruktörer Mikael Lindblad, Projektledare Peter Hjort, Lektor Målet med avhandlingen var att studera agila metoder, hur de används i mjukvaruföretag och hur de påverkar arbetet i ett programvaruutvecklingsteam. 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.

    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by University of Limerick Institutional Repository Lean Software Development – What Exactly Are We Talking About? Oisín Cawley1, Xiaofeng Wang2, Ita Richardson1, 1Lero-The Irish Software Engineering Research Centre, University of Limerick, Ireland. 2Free University of Bozen/Bolzano, ominikanerplatz 3 piazza Domenicani, I-39100 Bozen/Bolzano, Italy. 1{Oisin.Cawley, Ita.Richardson}@lero.ie, [email protected] Abstract. As the Software Engineering landscape continues to evolve and new paradigms are introduced, there can be a tendency for both industry and academia to enthusiastically embrace new approaches and march forward under whatever banner conventional wisdom has decided to adopt. One such banner is Lean Software Development, a paradigm that continues to see a growth in interest driven by the need for cost reductions within industry. The term lean attracts the attention of business, but precisely how it applies within software development is still being debated. In addition, its relationship to the better understood agile methodologies is also a topic for debate. Having been drawn into this research area ourselves, we present here a review of Lean Software Development and try to distil out for the reader some understanding of this somewhat undefined topic. We conclude with some thoughts on where this subject might go to from here. Keywords: Software Engineering, Software Development, Lean, Agile. 1 Introduction We are living in a period of history which is witnessing a drive for cost reductions and efficiencies across almost every business segment in almost every developed country. Traditionally businesses have been able to find efficiencies and cost reductions through automation and organisational restructuring of the more routine and repeatable processes.

DevOps is a hot topic in recent years. It emphasizes the combina- tion of development and operation. Agile is one of the most popular development methods, but Agile mainly focused on software development part, there is no more involvement in deployment and operations. In this case, many companies consider adopting DevOps in Agile to attempt to improve the situation. Objectives. The combination of two different technologies is bound to produce some challenges, whether it is for practitioners or researchers, it is very important to find these challenges and mitigate them, so this article aims to investigate the challenges of adopting DevOps in Agile, then through the systematic literature re- view and survey questionnaire to determine the corresponding mitigation strategy.
