Feature requests are steadily pouring in, but the team cannot respond to them. They are paralyzed. The codebase on which the company has “bet the business” is simply too hard to change. It's your job to clean up the mess and get things rolling again. Where do you begin? Your first task is to get the lay of the land by applying a family of techniques we'll call “Code Archaeology.”
In this session we will learn how to systematically explore a codebase. We'll look at what tools are available to help us out, slinging some wicked shell-fu along the way. We'll look at “code islands” and “code bridges,” and how to construct a “map of the code.” We'll also examine the wisdom that thought leaders like Michael Feathers and Dave Thomas have leant to this subject.
Once we've gained a thorough understanding of what we have in front of us, we'll learn approaches for getting the system under test and refactoring so that we can start to pick up the pace and respond to user requirements without making a bigger mess. You'll leave this session well prepared to tackle the next “big ball of mud” that gets dumped on your desk.

He is the author of Migrating to Cloud-Native Application Architectures from O'Reilly, and the host of the Software Architecture Radio podcast.
Matt is obsessed with the idea that enterprise IT “doesn’t have to suck,” and spends much of his time thinking about lean/agile software development methodologies, DevOps, architectural principles/patterns/practices, and programming paradigms, in an attempt to find the perfect storm of techniques that will allow corporate IT departments to not only function like startup companies but also create software that delights users while maintaining a high degree of conceptual integrity. He is currently the Global CTO of Architecture at Pivotal, and spends much of his time advising IT leadership on the effective adoption of cloud-native architectures.
Matt has spoken at conferences ranging from JavaOne to OSCON to YOW! and is a nine-year member of the No Fluff Just Stuff tour. Matt is also the founder and past president of the Memphis Java User Group.
