Recognize the integration signals
Common signals include conflicting versions, scheduled spreadsheet exports, repeated copy-and-paste, delayed status updates, duplicated identifiers, and manual reconciliation before every review.
Clarify the source of truth
For each shared entity or measure, define which system owns creation, which may update it, which only consumes it, and how identity is matched across the environment.
Choose the movement pattern
Not every need requires real-time integration. Select scheduled, event-based, API-led, or controlled file movement based on operating urgency, volume, reliability, and system constraints.
Design for failure and traceability
Reliable integration needs validation, error handling, retry logic, monitoring, and ownership. A silent failed transfer can be more dangerous than a visible manual process.
