Find Your Metaphor for Agile Software Design How you think about software design can have a big impact on how effective you are when you do it. All of us have different criteria for success, and some of them aren’t even conscious. We have to figure out what resonates for us so that we make the right choices, and we can get a clue about the right choices for us by looking at the metaphors we use when we talk about software. |

Building Autonomous DevOps Capability in Delivery Teams After setting up a DevOps team and adopting continuous delivery practices, product releases may not be as smooth as they could be. The missing ingredient requires empowerment and autonomy. |

The Value of Test-Driven Development when Writing Changeable Code Writing changeable code makes it easier and more cost-effective to add features to existing software. Writing changeable code doesn’t take longer, but it does require paying attention to certain things when building a system. It's important to have a good suite of unit tests that support refactoring code when needed, and test-driven development helps you create independently testable code. |

The Impact of Agile Quantified
Slideshow
For years, people have made recommendations for how to develop software in an agile way based almost entirely on intuition, folklore, and anecdotes. They've never been able to quantitatively show the accuracy or applicability of these recommendations. This session quantifies those recommendations in the most precise and objective terms, including a presentation of general findings in Larry Maccherone's research correlating agile practices to performance along the dimensions of productivity, predictability, quality, and time to market. These data can be used to make general decisions about what to focus on. The presentation also includes the numbers, so that instead of just saying that A is better than B, we can say that A is a 24 percent improvement in quality but a 10 percent reduction in productivity compared to B. |

Overcoming Test-Driven Damage
Slideshow
Test-driven development is supposed to help us refactor our code safely, but we often find that when we refactor our code, we also have to refactor our tests. What was supposed to add safety becomes a burden requiring time and effort. Writing good unit tests is a critical skill that developers need to master in order to get the most benefit from test-driven development. Tests must be unique, written at the right level of abstraction, and implementation-independent in order to be most valuable. In this session, David Bernstein will cover effective techniques for doing TDD that support building useful tests and quality code. You’ll learn how to approach TDD in a way that yields the right number and kind of tests to support improved refactoring. Working through a few code examples, you’ll see how many assertions are required to specify a linear range, exceptions, and other boundary conditions. |

DevOps Tools for Winning Agility
Slideshow
With a myriad of tools to choose from—open source, free, paid, and enterprise level—teams and organizations have seemingly endless options. Making the right tool decisions can impact the level of quality and success within DevOps projects. Kellyn Pot'Vin-Gorman discusses different tools, what tools work best together, and how—even in teams that are in silos—the right choices can make the difference between success and failure in DevOps implementations. Explore tools—such as Ansible, Jenkins, Maven, Delphix, Github, Liquibase, and Terraform—for automating builds and virtualization. Review reasons for choosing open source, “freemium,” or enterprise tools along with different hybrid tool combinations and explore why companies face new challenges as DevOps tools mature. |
