Teams can spend months reproducing existing behavior before users receive any benefit, while the original system continues to change. The strangler fig pattern takes a different approach: replace capabilities incrementally and route traffic to the new implementation as each slice becomes ready.</p> <h2 id="choose-a-bounded-slice">Choose a bounded slice</h2> <p>Start with a capability that has a clear input, output, and ownership boundary. Good first candidates are important enough to validate the migration approach but not so central that every subsystem must move at once.</p>
