Given an ancient codebase that makes refactoring risky and expensive, how do you clear a path to continued delivery? The old wisdom says the best time to plant a tree was 20 years ago, and the next best time is today. But if you already have a gnarled old source tree, preserve your software investment by planting a Strangler: a pattern for reaping continuous value from your existing system while growing new functionality alongside it.
We’ll take a quick look at a Strangler, demonstrate the basics of Mob Programming, then split into small groups to test-drive new features into the system. You’ll leave with a powerful strategy for extending the useful life of working, valuable software — especially when it’s hard to change — and with a free bonus development practice to accelerate your team’s learning.
