1. | 1 Develop in parallel and ship earlier with OpenAPI and mocking 1 PRESENTED BY: Lee Turner Senior Software Engineer, WireMock @leeturner
2. | • API-driven architectures - microservices, SOA, partner integrations • New product features often require new features in several APIs • Leads to dependency chains between teams 2 Serial vs. Parallel in API centric systems
