This document discusses how companies can transition to an API-led connectivity model to become more composable. It describes a progression from vertically integrated (v1) to distributed (v2) to composable (v3) models. The composable model leverages system, process, and experience APIs to connect applications, data sources, and services. This allows for easier integration, change management, and building new experiences and processes by combining different APIs. The document also discusses how an API-led approach requires enabling multiple roles and having a centralized governance model for managing and exchanging knowledge and assets.
