SAP / SAP Senior Level (10+ yrs) Interview questions

How do you measure go-live success and hypercare effectiveness after cutover?

Hypercare is the intensive support period immediately following go-live, when issues are most likely to surface as real users begin operating on the new system at full volume for the first time. Measuring its effectiveness requires both quantitative metrics and qualitative business feedback, not just "did the system stay up."

Metric CategoryExample
System stabilityUptime, performance against defined SLAs.
Issue volume/severityNumber and criticality of incidents raised, trend over the hypercare period.
Business process healthAre core processes (order-to-cash, procure-to-pay) completing correctly end-to-end?
User adoption/sentimentAre users actually able to complete their work, or working around the system?

A declining trend in issue volume/severity over the hypercare weeks, combined with genuine business stakeholder confirmation that core processes are functioning correctly, is generally a stronger signal of true go-live success than uptime metrics alone — a technically stable system that business users can't actually use effectively isn't a real success, which is why business process health and user sentiment matter as much as pure technical stability metrics.

What is hypercare?
Why isn't system uptime alone a sufficient measure of go-live success?
