API as the powerful EA lighthouse for a Composable Information System.
summary
Retail cooperative (Super U) runs a tangled landscape of 800+ applications while targeting ~15% market share, so APIs become the pragmatic EA lighthouse to stitch legacy monoliths, SaaS and microservices into a composable information system. Concrete practices: domain-owned stock and order APIs with JSON contracts, API-as-product backlogs, sync vs event tradeoffs (latency, retries, TCO), Figma-driven API design, metric-driven isolation of key flows, and tooling needs for policy, testing and AI-agent safety.
