Yazılım dünyasında ürünün hızlı bir şekilde pazara ulaşması için her geçen gün yeni yaklaşımlar belirlenmekte ve yeni metodolojiler benimsenmektedir. Son yıllarda bu konuda oldukça popüler olan ...DevOps metodolojisi, yazılım geliştirme yaşam döngüsünün diğer safhalarında olduğu gibi yazılım test aktivitelerinde ve test süreçlerinde köklü değişikliklerin oluşmasına ortam hazırlamıştır. Yazılım test aktivitelerinin yapısı büyük ölçüde değişime uğradığı için test süreç değerlendirmelerinde yeni modellere ihtiyaç duyulmaktadır. Gerçekleştirilen bu çalışmada, DevOps metodolojisinin test pratiklerini değerlendiren bir test süreç iyileştirme modeli sunularak bu ihtiyacı gidermek amaçlanmıştır. Model tasarımında akademi ve iş hayatındaki bilgilerden ortak olarak beslenmek adına literatürden ve deneyimli DevOps uzmanlarından yararlanılmıştır. Uzmanların katkısıyla DevOps test pratiklerinin değerlendirilmesi için önemli kriterler belirlenmiş ve bu kriterleri kapsayan yeni bir test süreç iyileştirme modeli oluşturulmuştur. Geliştirilen bu model DevOps pratiklerini gerçekleştiren bir firma üzerinde uygulanmıştır. Bu sayede hem modelin işlerliği hem de firmanın test olgunluğu değerlendirilmiştir. Değerlendirme süreci detaylı olarak gözlemlenmiş olup değerlendirme sonucu ve modelin uygulanabilirliği uzmanlar tarafından teyit edilmiştir.
DevOpsis a collaborative and multidisciplinary organizational effort to automate continuous delivery of new software updates while guaranteeing their correctness and reliability. The present survey ...investigates and discusses DevOps challenges from the perspective of engineers, managers, and researchers. We review the literature and develop a DevOps conceptual map, correlating the DevOps automation tools with these concepts. We then discuss their practical implications for engineers, managers, and researchers. Finally, we critically explore some of the most relevant DevOps challenges reported by the literature.
Customer demands, competition, regulatory environments, and sophisticated external threats have all increased the importance of DevOps in IT organizations. However, DevOps adoption is still uneven, ...emphasizing the need to provide management with relevant IS data and insights. Regrettably, there is a measurement inefficiency between these capabilities.
To sustain promoting DevOps adoption, Design Science Research (DSR) is done using two multivocal literature reviews and semi-structured interviews to elicit key DevOps metrics and capabilities. Thirty-seven DevOps capabilities and twenty-four metrics were defined, classified, and validated by conducting 31 interviews with practitioners and experts leading to an outcome-based capability evaluation matrix, for promoting DevOps implementation and adoption. Empowering teams and organizational culture have the greatest impact.
An Empirical Taxonomy of DevOps in Practice Macarthy, Ruth W.; Bass, Julian M.

Conference Proceeding
DevOps is described as a software engineering culture and philosophy that utilises cross-functional teams to build, test and release software faster and more reliably through automation. Research ...shows that its adoption speeds up software delivery time, improve quality, security, and collaboration in software development. One controversial issue has been whether DevOps is an organisation-wide culture or a job description. As DevOps is an emerging concept, its definitions and best practices are still hazy, making its implementation in practice less informed and somewhat risky. The rising trend of DevOps adoption among software development practitioners therefore heightens the need for in-depth investigation into its implementation.This paper seeks to contribute to the above by critically examining DevOps implementation in practice through an exploratory case study, based on interviews with 11 industry practitioners across nine organisations. Transcripts of interviews were coded and analysed using a method informed by Grounded Theory. This study provides an empirical taxonomy of DevOps implementation, describing developers' interaction with On-premises Ops, Outsourced Ops, DevOps teams, and DevOps bridge teams. We present a novel mapping of the approaches to on-premises and cloud-based deployments, and identified the facilitators of DevOps practices in the different modes. We further identified three distinct groups of activities in the fourth mode: provisioning and maintenance of physical systems, function virtualisation and creation of automated pipelines, and development, deployment and maintenance of applications, which may have given rise to the implementation of DevOps as bridge teams. Interviewees claimed these distinctions allowed developers to focus on delivering value for the business.
Context. To meet the demands of customers and market, Information Technology (IT) organizations are seeking to implement DevOps. While many succeed in DevOps adoption, others lack the knowledge on ...how to incorporate DevOps culture, process, measurements, and techniques in their business. Thus, successful adoption is still inconsistent, highlighting the need to provide management with relevant information to support the development of DevOps Capabilities effectively. But what are these Capabilities? Unfortunately, there is still a lack of clarity about DevOps Capabilities and their relationships to DevOps Practices and Outcomes among researchers and practitioners. Objective. This research aims to gather community consensus on the relationship between Capabilities and Practices, so a better DevOps implementation can be mapped. Seeking to define DevOps Capabilities and Practices concepts and to identify, organize and summarize Capabilities as they relate to Practices. Method. A Multivocal Literature Review (MLR) is conducted, with 93 documents gathered and thoroughly examined from throughout the community, including books, scientific articles, white papers, and conferences, among others. Results. This survey contributes a list of 37 organized Capabilities, their mentions in literature, and their definitions. The concepts of Practices and Capabilities were mapped and categorized in an ordered taxonomy. It is concluded that industry research has much outweighed scientific research on this topic, with Capabilities evolving dynamically over time, reinforcing team collaboration and communication as the most crucial one. The study's Outcomes will assist researchers and practitioners understand how Capabilities and Practices are related at different levels and how to better implement them.
