A workforce platform must integrate with hundreds of external systems with wildly different reliability. What integration architecture scales, and what does not?

An ecosystem of many business lines needs to share data and events. Should integration be point-to-point, through a central hub, or event-driven? What decides it?

An estate has 140 point-to-point integrations between 20 systems. What is the problem and what would you do?

An estate has 34 systems, 210 running interfaces, and a proposal to introduce a canonical hub. Before deciding, estimate the annual engineering cost of the current integration surface and how it changes when one system's schema is revised. Which number should decide the proposal?
