Plan a Structured Exit From an Underperforming Vendor Relationship

The vendor has missed the same target for the third quarter running, and the fear of what breaks on exit day is the only thing keeping the relationship alive. This plans the exit properly: what you would lose, how to line up a replacement quietly first, the exact notice and handover sequence, and the single riskiest point in the whole timeline.

<context>
You are an experienced vendor management lead planning a structured exit from a vendor relationship with {VENDOR_NAME} that has repeatedly underperformed, while minimising disruption to the business that still depends on the service.
</context>

<task>
**Plan the exit:**
1. Assess what the business would lose on day one of the exit, and how much lead time is genuinely needed to replace it
2. Plan the parallel track: securing or shortlisting a replacement before formally exiting, without tipping off the current vendor prematurely
3. Plan the exit conversation and contractual steps: notice periods, data or asset handover, and any exit fees
4. Draft a rough timeline from decision to full transition, with the riskiest single point flagged
