Devops and Testers White Paper
White Paper DevOps and Testers DevOps is part of an overall approach that organizations use to deliver software frequently and with high quality. The most obvious outcome of successful DevOps implementations is the reduction in the time it takes for software changes to transition from an idea to production.

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]. -

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. -

As organizations start to move into an agile development methodology, they start to uncover other processes that can be accelerated, such as delivery by DevOps and testing by Continuous Testing. The acceleration that is set in motion via agile makes it necessary to accelerate the release schedule. In order to ensure a successful release, an organization must adopt continuous testing to make sure the conveyer belt does not break down. The modernization maturity model has these three distinct phases: AGILE Agile software development is a different way of thinking about approaching the challenge of development time. -
White Paper Getting Started with Continuous Integration in Software
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.
