Luis Weir, CTO of Capgemini UK's Oracle practice, discusses the role of APIs and microservices in digital transformation. He argues that technology alone does not drive disruption but lack of adaptability to customer needs. Weir outlines the API value chain and how organizations can move from tactical to strategic use of APIs. Case studies of Cargill and IKEA demonstrate how a next-generation API platform unlocked data and enabled their digital supply chains.
