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.

IBM Developer for Z/OS Enterprise Edition
Solution Brief IBM Developer for z/OS Enterprise Edition A comprehensive, robust toolset for developing z/OS applications using DevOps software delivery practices Companies must be agile to respond to market demands. The digital transformation is a continuous process, embracing hybrid cloud and the Application Program Interface (API) economy. To capitalize on opportunities, businesses must modernize existing applications and build new cloud native applications without disrupting services. This transformation is led by software delivery teams employing DevOps practices that include continuous integration and continuous delivery to a shared pipeline. For z/OS Developers, this transformation starts with modern tools that empower them to deliver more, faster, with better quality and agility. IBM Developer for z/OS Enterprise Edition is a modern, robust solution that offers the program analysis, edit, user build, debug, and test capabilities z/OS developers need, plus easy integration with the shared pipeline. The challenge IBM z/OS application development and software delivery teams have unique challenges with applications, tools, and skills. Adoption of agile practices Application modernization “DevOps and agile • Mainframe applications • Applications require development on the platform require frequent updates access to digital services have jumped from the early adopter stage in 2016 to • Development teams must with controlled APIs becoming common among adopt DevOps practices to • The journey to cloud mainframe businesses”1 improve their -

Managing Defects in an Agile Environment
Managing Defects in an Agile environment Auteur Ron Eringa Managing Defects in an Agile environment Introduction Injecting passion, Agility Teams often struggle with answering the following and quality into your question: “How to manage our Defects in an organisation. Agile environment?”. They start using Scrum as a framework for developing their software and while implementing, they experience trouble on how to deal with the Defects they find/cause along the way. Scrum is a framework that does not explicitly tell you how to handle Defects. The strait forward answer is to treat your Defects as Product Backlog Items that should be added to the Product Backlog. When the priority is set high enough by the Product Owner, they will be picked up by the Development Team in the next Sprint. The application of this is a little bit more difficult and hence should be explained in more detail. RON ERINGA 1. What is a defect?

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. -

To create good sto- ries we focus on six attributes. A good story is: • Independent • Negotiable • Valuable to users or customers •Estimatable •Small •Testable Bill Wake, author of Extreme Programming Explored and Refactoring Workbook, has suggested the acronym INVEST for these six attributes (Wake 2003a). Independent As much as possible, care should be taken to avoid introducing dependencies between stories. Dependencies between stories lead to prioritization and plan- ning problems. For example, suppose the customer has selected as high priority a story that is dependent on a story that is low priority. Dependencies between stories can also make estimation much harder than it needs to be. For example, suppose we are working on the BigMoneyJobs website and need to write stories for how companies can pay for the job openings they post to our site. We could write these stories: 1. A company can pay for a job posting with a Visa card. 2. A company can pay for a job posting with a MasterCard. 17 18 WRITING STORIES 3. A company can pay for a job posting with an American Express card. Suppose the developers estimate that it will take three days to support the first credit card type (regardless of which it is) and then one day each for the second and third. -

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. -

Use Cases, User Stories and Bizdevops
Use Cases, User Stories and BizDevOps Peter Forbrig University of Rostock, Chair in Software Engineering, Albert-Einstein-Str. 22, 18055 Rostock [email protected] Abstract. DevOps is currently discussed a lot in computer science communi- ties. BizDev (business development) is only mentioned once in a computer sci- ence paper in connection with Continuous Software Engineering. Otherwise it is used in the domain of business administration only. Additionally, there seems to be a different interpretation of the term in the two communities. The paper discusses the different interpretations found in the literature. Addi- tionally, the idea of BizDevOps is discussed in conjunction with further ideas of taking new requirements for software features into account. These requirements can be described by models on different level of granularity. Starting points are use cases, use-case slices, user stories, and scenarios. They have to be commu- nicated between stakeholders. It is argued in this paper that storytelling can be a solution for that. It is used in as well in software development as in manage- ment. Keywords: BizDev, DevOps, BizDevOps, Continuous Requirements Engineer- ing, Continuous Software Engineering, Agile Software Development, Storytell- ing. 1 Introduction Developing Businesses if often related with the development of software because nowadays business processes have to be supported by IT. Continuous requirements engineering has to be performed to provide continuously the optimal support. Contin- uous business development seems to be a good description for the combined devel- opment of software and business. This term is not used so very often. Nevertheless, it exists like in [17]. However, more often the abbreviation BizDev (business development) is used.
