Illustrative and anonymized representative case. It describes a common enterprise delivery pattern, not a named customer engagement or a promise of outcome.
The situation
The decision to make
A customer-support copilot was tightly coupled to one model provider and a legacy retrieval path. Product and support teams needed a safer way to compare an alternative configuration without changing the experience customers already relied on.
This representative case describes a support organization serving English, Bahasa Melayu and Chinese users with a living enterprise knowledge base. The migration decision depends on task quality, latency, safety and a clear ability to reverse course.
CoreShift approach
A staged implementation path
Discover the existing path
Capture model calls, prompts, retrieval settings, source documents and fallback behavior that shape the live assistant.
Build a relevant evaluation set
Test representative support questions, including the languages, document types and escalation scenarios that occur in daily operations.
Run in shadow mode
Compare current and candidate outputs away from end users, then use controlled traffic stages only when the evidence supports a change.
