The weeks immediately after go-live are where configuration gaps that weren't caught in UAT tend to surface — under real payroll cycles, real leave requests, and real edge cases. We run a defined hypercare window where the first one or two payroll cycles are monitored closely and user queries are resolved through a dedicated support channel rather than an open-ended email thread.
Configuration fixes during this window are turned around quickly, since a gap left unresolved through a second or third payroll cycle tends to erode trust in the new system faster than almost anything else in the rollout.
