Today, even the largest development organizations are turning to agile methodologies, seeking major productivity and quality improvements. However, large-scale agile development is difficult, and publicly available case studies have been scarce. Now, three agile pioneers at Hewlett-Packard present a candid, start-to-finish insider’s look at how they’ve succeeded with agile in one of the company’s most mission-critical software environments: firmware for HP LaserJet printers. This book tells the story of an extraordinary experiment and journey. Could agile principles be applied to re-architect an enormous legacy code base? Could agile enable both timely delivery and ongoing innovation? Could it really be applied to 400+ developers distributed across four states, three continents, and four business units? Could it go beyond delivering incremental gains, to meet the stretch goal of 10x developer productivity improvements? It could, and it did—but getting there was not easy. Writing for both managers and technologists, the authors candidly discuss both their successes and failures, presenting actionable lessons for other development organizations, as well as approaches that have proven themselves repeatedly in HP’s challenging environment. They not only illuminate the potential benefits of agile in large-scale development, they also systematically show how these benefits can actually be achieved. Coverage includes: • Tightly linking agile methods and enterprise architecture with business objectives • Focusing agile practices on your worst development pain points to get the most bang for your buck • Abandoning classic agile methods that don’t work at the largest scale • Employing agile methods to establish a new architecture • Using metrics as a “conversation starter” around agile process improvements • Leveraging continuous integration and quality systems to reduce costs, accelerate schedules, and automate the delivery pipeline • Taming the planning beast with “light-touch” agile planning and lightweight long-range forecasting • Implementing effective project management and ensuring accountability in large agile projects • Managing tradeoffs associated with key decisions about organizational structure • Overcoming U.S./India cultural differences that can complicate offshore development • Selecting tools to support quantum leaps in productivity in your organization • Using change management disciplines to support greater enterprise agility

This book explores coordination within and between teams in the context of large-scale agile software development, providing readers a deeper understanding of how coordinated action between teams is achieved in multiteam systems. An exploratory multiple case study with five multiteam systems and a total of 66 interviewees from development teams at SAP SE is presented and analyzed. In addition, the book explores stereotypes of coordination in large-scale agile settings and shares new perspectives on integrating conditions for coordination. No previous study has researched this topic with a similar data set, consisting of insights from professional software development teams. As such, the book will be of interest to all researchers and practitioners whose work involves software product development across several teams.

Creativity and productivity, rapid adaptation to change, value for the customer—these are just some of the advantages of implementing agile practices in project work. However, agile practices have been most widely and successfully undertaken in the context of small, colocated teams working on small software projects, known as the "agile sweet spot." In this monograph, Brian Hobbs and Yvan Petit explore the use and impact of agile outside of the agile sweet spot. Through a case study and survey questionnaire, they uncover research questions that have remained largely unexamined in the literature, on the project level as well as on the organizational level, namely: •What challenges are encountered when applying agile approaches to large, multi-team software projects and what practices have been developed to alleviate these challenges? •How does the context of large, complex organizations affect the adaptation and adoption of agile approaches and vice versa? An illuminating study of this emerging field, Agile Approaches on Large Projects in Large Organizations opens the door to further investigation on the future role of project managers, the use of scaling frameworks at the program and portfolio levels, and the effects of DevOps, one of the recent trends in agile software development.

The agile transformation is an act of transforming an organization’s form or nature gradually to one that can embrace and thrive in a flexible, collaborative, self-organizing, and fast-changing environment. It seems like most of the companies starting an agile transformation never reach the goal of agility, but there are those few that truly become agile and reap incredible benefits by utilizing DevOps as well. This book introduces the theory and practice of the "double-flywheels model" of Continuous Delivery 2.0: Discovery Loop, which allows information technology (IT) organizations to help businesses figure out the most efficacious ways to develop. Additionally, it explores applications of the Verification Loop that allows IT organizations to deliver value quickly and safely with high quality. Along the way, the book provides an array of insights and case studies that dive into all the aspects of software delivery, and how to implement Continuous Delivery in the most economical way for long-run business development. Features Organization culture and software architecture Business requirement management Pipeline and tooling Branching and releasing strategy Automation strategy Configuration and artefacts management Deployment and production healthy The case studies at the end of the book—scenarios in which the author was personally involved—are explored in depth and meticulously detailed in order to represent typical agile transition scenarios that will benefit all readers.

How Can DevOps Make You Antifragile? All complex computer systems eventually break, despite all of the heavy-handed, bureaucratic change-management processes we throw at them. But some systems are clearly more fragile than others, depending on how well they cope with stress. In this O’Reilly report, Dave Zwieback explains how the DevOps methodology can help make your system antifragile. Systems are fragile when organizations are unprepared to handle changing conditions. As generalists adept at several roles, DevOps practitioners adjust more easily to the fast pace of change. Rather than attempt to constrain volatility, DevOps embraces disorder, randomness, and impermanence to make systems even better. This concise report covers: Why Etsy, Netflix, and other antifragile companies constantly introduce volatility to test and upgrade their systems How DevOps removes the schism between developers and operations, enlisting developers to deploy as well as build Using continual experimentation and minor failures to make critical adjustments—and discover breakthroughs How an overreliance on measurement and automation can make systems fragile Why sharing increases trust, collaboration, and tribal knowledge Download this free report and learn how the DevOps philosophy of Culture, Automation, Measurement, and Sharing makes use of changing conditions and even embarrassing mistakes to help improve your system—and your organization. Dave Zwieback has been managing large-scale, mission-critical infrastructure and teams for 17 years.
