larger batch sizes compound effort needed to identify causes ii. Unit tests – test a single method, class, or function in isolation to ensure operates as designed iii. Acceptance tests – test application Coined by Martin Fowler in 2004 ii. Strangler Application 1. Put existing functionality behind an API 2. New functionality implemented in new services with new architecture 3. Make calls to old system
