Readiness before a live process
- 12 months out: coaching and gap closure on architecture, security, OSS and data room shape
- 6 months out: targeted remediation and narrative rehearsal
- 3 months out: final data-room assembly and vendor DD kick-off if not already running
Typical live vendor DD (about 2–4 weeks)
- Scope, access plan and adviser alignment (days 1–3)
- Evidence gathering and interviews (week 1–2)
- Draft findings and management review (week 2–3)
- Final report and buyer Q&A support (week 3–4)
Timelines compress or extend with entity count, security depth and parallel buyer activity. See indicative cost drivers .
