Research on the topic of adopting agile methods in development teams Lägerhyddsvägen 1 is extensive. In the literature key enabling factors are identified and numerous House 4, Level 0 benefits of agile ways of working are named. Less attention has been payed to Postal address: the non-software functions in software development organizations, though. Box 536 Moreover, little is known about how well the enabling factors and benefits for 751 21 Uppsala software teams translate to other teams in the organization. The goal of this Telephone: study is to evaluate what benefits agile methods provide to non-software teams, +46 (0)18 – 471 30 03 whether the enabling factors are similar and what the challenges and drawbacks Telefax: for adopting agile methods in commercial teams are. Using the case of the +46 (0)18 – 471 30 00 Swedish Software-as -a-Service company Funnel, which introduced agile Web page: practices into their commercial teams, these questions are tackled. The study http://www.teknik.uu.se/student-en/ finds that knowledge transfer and governance are core areas that need to be engaged in during the adoption process.

Designing Software Architecture to Support Continuous Delivery and Devops: a Systematic Literature Review
Designing Software Architecture to Support Continuous Delivery and DevOps: A Systematic Literature Review Robin Bolscher and Maya Daneva University of Twente, Drienerlolaan 5, Enschede, The Netherlands [email protected], [email protected] Keywords: Software Architecture, Continuous Delivery, Continuous Integration, DevOps, Deployability, Systematic Literature Review, Micro-services. Abstract: This paper presents a systematic literature review of software architecture approaches that support the implementation of Continuous Delivery (CD) and DevOps. Its goal is to provide an understanding of the state- of-the-art on the topic, which is informative for both researchers and practitioners. We found 17 characteristics of a software architecture that are beneficial for CD and DevOps adoption and identified ten potential software architecture obstacles in adopting CD and DevOps in the case of an existing software system. Moreover, our review indicated that micro-services are a dominant architectural style in this context. Our literature review has some implications: for researchers, it provides a map of the recent research efforts on software architecture in the CD and DevOps domain. For practitioners, it describes a set of software architecture principles that possibly can guide the process of creating or adapting software systems to fit in the CD and DevOps context. 1 INTRODUCTION designing new software architectures tailored for CD and DevOps practices. The practice of releasing software early and often has For clarity, before elaborating on the subject of been increasingly more adopted by software this SLR, we present the definitions of the concepts organizations (Fox et al., 2014) in order to stay that we will address: Software architecture of a competitive in the software market. -
Best Practices in Agile Software Development
Universiteit Leiden ICT in Business Best practices in Agile software development A qualitative study on how organizations identify, analyze, improve, represent and document (best) practices to improve their software development processes. Name: Ing. R.H.J.C. (Roy) van Wel Student-no: 1310194 Date: 25/08/2013 1st supervisor: C.J. (Christoph) Stettina MSc. 2nd supervisor: Dr. L.P.J. (Luuk) Groenewegen MASTER'S THESIS Leiden Institute of Advanced Computer Science (LIACS) Leiden University Niels Bohrweg 1 2333 CA Leiden The Netherlands Acknowledgements By completing this Thesis I finished my education and will receive my Master of Science degree. Of course, I was not able to finish my Thesis without supervision. Therefore I would like to first thank Dr. Luuk Groenewegen, especially for making time available on short notice. Also I would like to give special thanks to Christoph Stettina MSc. for his supervision and coaching skills. You were there when I needed your help and you always gave me enough space for self-deployment. Although my background is ICT-related, I found the Thesis proposal from Christoph very intriguing. The initial objective was to look on currently available Agile practices and compare the applicability of existing process model descriptions to document Agile practices in an accessible but complete manner. During my literature study I got really enthusiastic about the subject Agile software development and decided to also examine how organizations identify, analyze and improve their practices. During my literature research I found very interesting literature how practices can be identified by executing workshops. Because I was really curious how this would work in practice, I asked André Lauwerijssen, a very skilled Scrum Master, to execute the workshop with me. -
