You are supporting a customer deployment where a newly integrated enterprise content workflow starts failing intermittently in production after go-live. The issue spans multiple systems, including document ingestion, identity federation, and downstream archive synchronization, and no single team owns the full path end to end. The customer’s operations team is escalating because business-critical documents are delayed, your delivery team believes the root cause may sit in a third-party dependency, and the account team is pushing for a fast answer before an executive status call. You need to troubleshoot the issue while keeping the customer informed, limiting business impact, and deciding whether to stabilize forward or trigger a rollback.
Describe a time when you had to troubleshoot a complex technical issue. How did you structure the investigation, align stakeholders, manage risk, and drive the issue to resolution?
