Enterprise Procurement Risk Memo + +## Situation +The buyer entered procurement for annual renewal and asked for a bundled proposal that combines platform licensing, implementation support, and SLA uplift. +Legal requested two rounds of redlines and now requires explicit language for data residency, deletion timelines, and subprocessors. +Security asked for the full questionnaire, pen-test summary, SOC evidence package, and a named escalation owner for incident response coordination. +Finance requested price hold terms through quarter close and requires a clean net amount with no conditional side letters. + +## Current Friction +The commercial owner reports that each team is operating on a different timeline. +Procurement prefers a single consolidated response packet, but legal and security are still updating separate drafts. +The buyer champion is supportive but cannot route final approval until the redline and security sections are complete. +Two approvers are out next week, which introduces a calendar risk for final signoff. + +## Evidence From Recent Calls +- Buyer said the risk is not product fit, it is internal process load. +- Procurement requested one owner for all responses to avoid thread drift. +- Legal asked for an explicit breach notification interval in the MSA. +- Security flagged third-party dependency disclosure as incomplete. +- Finance asked for forecast certainty before they release PO authority. + +## Operational Notes +1. The account team should treat this as a coordination problem, not a persuasion problem. +2. Every open item needs owner, due date, and blocking dependency. +3. Replies should be centralized in one tracker to avoid inconsistent statements. +4. Escalation should happen early when legal language depends on security attestations. +5. The champion should get a concise status summary after each workday. + +## Risk Register +- **Timeline risk:** medium-high due to calendar compression and approver availability. +- **Compliance risk:** medium due to unresolved security questionnaire fields. +- **Commercial risk:** medium because procurement is requesting fixed pricing through quarter end. +- **Execution risk:** high if response ownership remains fragmented across teams. + +## Recommended Plan +Create a single response packet and assign one coordinator. +Pre-fill all known legal and security answers from existing templates. +Schedule a thirty-minute cross-functional triage with legal, security, and sales operations. +Lock a daily cutoff time for updates and send one canonical status note to stakeholders. +Escalate unresolved blockers to leadership forty-eight hours before target sign date. + +## Success Criteria +- Security questionnaire submitted with no unresolved critical fields. +- Redline package accepted or narrowed to non-blocking items. +- Pricing terms approved by finance for the requested window. +- Purchase order process initiated before the internal close date. +- Owner confirms all blocker tickets are either resolved or explicitly waived. + diff --git a/crates/omnigraph/tests/fixtures/search.gq b/crates/omnigraph/tests/fixtures/search.gq new file mode 100644 index
