When you're mired in an ancient codebase that makes refactoring risky and expensive, how do you clear a path to continued delivery? According to the old saw, the best time to plant a tree is 20 years ago, and the next best time is today. But if you already have a gnarled old source tree, an old saw is the wrong tool. Instead, plant a Strangler: a pattern for preserving your software investment by arranging for new functionality to grow in a new codebase.

As a mob, we'll test-drive a Strangler, then test-drive new features into it. Don't know what to try next? Take the keyboard. Got an idea? Step away and talk someone else through it. You'll leave with a powerful strategy for extending the useful life of working, valuable software -- _especially_ when it's hard to change. We'll also send you home with a free bonus development practice to accelerate your team's learning. For a limited time only!
