A System Integration Checklist

Post date: Mar 17, 2017 4:53:45 AM

Just a few basic things to check list when building a integration:

Generic purpose of integration
Is all the required source data even available
Cost benefit analysis
Test cases
Transfer Triggers / Interval / Schedule
Data sources
Data mapping (Avoid if possible)
Transfer format
Data validation
Destination
Transport method
Data Security / Authentication / Signing / Encryption
Timeouts / Retransmissions / Other exceptions
Logging & Reporting
Monitoring & Alerts
Key responsible contacts

That's just what I do, every time when I need to build one.

If the data mapping gets very complex. It's highly likely that nobody in the client organization is able to maintain it in future. If it requires stretching to get it right during the development. It's almost guaranteed that it'll fail in future. They'll be blaming the integration.
