Integration is a product you maintain, not a project you finish
Ariba releases quarterly. S/4HANA patches. APIs version. An integration estate without monitoring and ownership decays on a schedule you did not choose.

The failure mode nobody alerts on
The loudest integration failures are easy: the interface is down, someone notices, someone fixes it. The expensive failures are quiet — an interface that runs but drops a field, a mapping that no longer matches a new release, a reconciliation gap discovered by finance at month-end.
Quiet failures happen because most integration estates have no monitoring worth the name. Success is assumed when no error was thrown.
Start with an interface catalogue
Every interface gets a row: systems, direction, owner on both sides, business impact if it fails, reconciliation method. This is one document, maintained, that turns integration from tribal knowledge into an operated asset.
Reconciliation is the discipline that matters most. For each critical flow, something — a report, a control total, a count — proves the two sides agree. Absence of errors is not evidence of success.
Test against the release calendar
Ariba's CI upgrades and quarterly releases change behaviour underneath your mappings. The estates that survive this share one habit: release notes are read by a named person, affected interfaces are regression-tested in the preview window, and the business hears about changes before they land.
Integration is the fabric the whole estate hangs on. Treat it as a product with an owner and a maintenance budget, not as go-live plumbing.
