In-Person Training
Building evolutionary architecture

Neal Ford (ThoughtWorks), Rebecca Parsons (ThoughtWorks)
Sunday, February 25 & Monday, February 26, 9:00am - 5:00pm
Location: Concourse B

Participants should plan to attend both days of this 2-day training course. Platinum and Training passes do not include access to tutorials on Tuesday.

Neal Ford and Rebecca Parsons offer a new perspective on evolving architecture, making “evolvability” a first-class “-ility” in software projects.

What you'll learn, and how you can apply it

By the end of this two-day training course, attendees will understand:

  • The concepts of building architectures that support constant change, both from business and disruptive technology changes
  • The role of engineering practices such as continuous delivery and DevOps and how they apply to evolutionary architectures
  • How to discover, define, and execute fitness functions to preserve architectural characteristics as the system evolves
  • How to analyse business problems to discern architectural characteristics
  • How code reuse impacts evolvability
  • How enterprise architecture must evolve

And they'll be able to:

  • Use ATAM utility trees to define and track architectural characteristics
  • Define deployment pipeline stages to apply fitness functions
  • Choose architectural patterns based on business, nonfunctional requirements, and inherent evolvability
  • Compare and contrast the evolvability of disparate architectural patterns and styles
  • Define automated governance activities
  • Protect a variety of architecture characteristics to prevent degradation over time

For a variety of reasons, parts of software systems resist change, becoming more brittle and intractable over time. However, the world we inhabit has exactly the opposite characteristic: the software development ecosystem exists in a state of dynamic equilibrium. New tools, techniques, approaches, and frameworks constantly impact this equilibrium in unanticipatable ways.

While this creates a headache for brittle systems, it also provides the ultimate solution. Over the last few years, incremental developments in core engineering practices for software development have created the foundations for rethinking how architecture changes over time, along with ways to protect important architectural characteristics as it evolves. An evolutionary architecture supports building systems that allow architects and developers to make sweeping changes to the most important parts of their systems with confidence.

Neal Ford and Rebecca Parsons offer a new perspective on evolving architecture, making “evolvability” a first-class “-ility” in software projects. Neal and Rebecca walk you through a logical framework for identifying and protecting parts of the architecture that evolve, which helps you identify the important dimensions, define fitness functions to ensure compliance, and use incremental change engineering practices such as deployment pipelines and other continuous delivery practices to automatically verify fitness. Along the way, they cover practices that allow architects and engineers to build continual architectures that evolve cleanly without the need for a crystal ball. You’ll leave able to build systems that support ongoing change with confidence that the important qualities won’t degrade.
