      Introduction to Disciplined Agile Delivery - Second Edition - Scott Ambler

      Chapter 1

      Introduction

      Many organizations are struggling to be successful with mainstream agile methods such as Scrum. Sometimes, the impulse is to give up and try the next great thing such as Lean or Scaled Agile Framework (SAFe®). The reality is that the source of failure of existing agile adoptions can often be traced to either the misapplication of core agile principles or a naïve approach to scaling agile and the need to address enterprise concerns.

      Adding to the confusion is the constant bickering in the agile community about which method is best between Scrum, Extreme Programming (XP), Kanban, SAFe, and others. The reality is that most organizations can benefit from a number of these strategies, albeit with some consistency that a common tool kit can provide. This is where the Disciplined Agile™ (DA) tool kit comes in.

      DA is a hybrid of existing methods that provides the flexibility to use various approaches, as well as plugging some gaps not addressed by mainstream agile methods. In a nutshell, DA, and more importantly, the Disciplined Agile Delivery (DAD) portion of it that is the focus of this book, is pragmatic agile. It describes proven strategies to adapt and scale agile initiatives that suit the unique realities of your enterprise, without having to figure it all out by yourself.

      The book Choose Your WoW! A Disciplined Agile Delivery Handbook for Optimizing Your Way of Working is the definitive guide for DAD. We have key information about DA, in general, at PMI.org/disciplined-agile.

      While Choose Your Wow is a great overview and reference guide, it is over 400 pages. We felt that it would be useful to summarize DAD into a quick read to show how it can be applied in a typical situation. That thinking led to the first edition of Introduction to Disciplined Agile Delivery, published in the third quarter of 2015. We have found that organizations that simply take a bit of time to understand what DAD is, as well as what it is not, see very quickly the obvious benefits of DAD.

      We wrote this short book in the hope that after having invested just an hour or two to learn about what DAD actually is, you are convinced that it is worthwhile to further investigate the possible fit for DAD within your organization.

      Some quick facts about DAD:

      •DAD is the delivery portion of the Disciplined Agile (DA) tool kit. DAD is a key component of Disciplined DevOps, which in turn is part of DA's value stream layer, which is part of the Disciplined Agile Enterprise (DAE). The book An Executive's Guide to the Disciplined Agile Tool Kit provides an overview of DA, as does the appendix at the back of the book.

      •DA is resonating within organizations around the world. Organizations that have adopted, or are in the process of adopting, DA include large financial institutions, software companies, e-commerce companies, restaurant chains, government agencies, and many others. By adoption, we mean either planning or actively implementing it across their entire organization, not just with one or two teams.

      •Although DAD was originally developed at IBM, it is now the intellectual property of Project Management Institute (PMI), and is available at no cost to PMI members.

      •The certification program is described at PMI.org.

      •DA is not a replacement for existing agile and lean methods. It complements them and, in many cases, extends them to be enterprise ready.

      Chapter 2

      Reality Over Rhetoric

      One of the reasons why DAD is quickly growing in popularity is that it acknowledges how organizations that are effectively scaling agile are really doing things. We think that it is important to clear up some of the misconceptions regarding the hype of agile purism versus what we have found to be really happening based on both our hands-on experience with many clients around the world and our comprehensive industry research.¹

      Chapter 3

      Disciplined Agile Delivery in a Nutshell

      Key Points

      •DAD is the delivery portion of the Disciplined Agile (DA) tool kit, not just another methodology.

      •If you are using Scrum, XP, or Kanban, you are already using variations of a subset of DAD.

      •DAD provides six life cycles to choose from; it doesn't prescribe a single way of working. Choice is good.

      •DAD focuses on achieving common goals in an agile manner, not the production of specific work products or following a prescriptive agile strategy.

      •DAD addresses key enterprise concerns not described by mainstream methods such as Scrum.

      •DAD is complementary to SAFe, yet far less prescriptive and more practical for most enterprises.

      •DAD shows how agile works from beginning to end.

      •DAD provides a flexible foundation from which to scale mainstream methods.

      •While DAD's philosophy is consistent with that of the Manifesto for Agile Software Development (Agile Manifesto), it includes additional guidance to be effective in more complex enterprise situations.

      •It is not difficult to get started with DAD.

      Many organizations start their agile journey by adopting Scrum because it describes a good strategy for leading agile software teams. However, Scrum is only a small part of what is required to deliver sophisticated solutions to your stakeholders. Invariably, teams need to look to other methods to fill in the process gaps. When looking at other methods, there is considerable overlap and conflicting terminology that can be confusing to practitioners, as well as outside stakeholders. Worse yet, people don't always know where to look for advice, or even know what issues they need to consider.

      To address these challenges, Disciplined Agile Delivery (DAD) is a people-first, learning-oriented, hybrid agile approach to IT solution delivery. Delivery (DAD) provides a more cohesive approach to agile solution delivery. It supports several risk value delivery life cycles, is goal driven,
