Engagement Architecture
Three phases.
Every deliverable named.
We don't sell vague consulting. We walk you through the exact sequence that has closed 483 observations at 38 facilities in the last four years.
01
Timeline
Weeks 1–3
We read your system before you read ours.
Before a single recommendation is made, our team conducts a structured documentary review of your quality management system against current FDA expectations. We score every gap against inspection likelihood — not theoretical risk.
Deliverables
- Site Master File audit (current vs. required)
- QMS gap matrix with FDA 21 CFR mapping
- Inspection-readiness score (0–100)
- Prioritized remediation roadmap
3.2
avg findings closed per engagement week
02
Timeline
Weeks 4–10
Corrective actions that survive the follow-up.
Our remediation work is built to withstand a second inspection. Each CAPA is written with effectiveness verification criteria already embedded. We draft, review, and cross-reference — so your team presents documentation that answers questions before they are asked.
Deliverables
- CAPA effectiveness review protocols
- Batch record template remediation
- SOP revision with change control packets
- Mock 483 response drafts (full narrative)
- Training records remediation plan

03
Timeline
Inspection Week + 30-day close-out
We are in the room — or we are on the line.
When the investigator arrives, you have two choices: improvise or execute. Our team provides on-site or remote back-room support — real-time document retrieval, response coaching, and nightly debrief with Day+1 strategy. The inspection ends. The relationship does not.
Deliverables
- Back-room command structure setup
- Document retrieval protocol
- Daily debrief reports
- 483 observation response (48-hr turnaround)
- Close-out letter and EIR preparation

Named deliverables.
Not consulting hours.
Every engagement is scoped to specific artifacts — documents you can open, reference, and hand to an investigator on Day 1.
Site Master File Audit
Line-by-line comparison against ICH Q10 and current FDA expectations. Every gap scored, every section cross-referenced to the inspection risk matrix.
38
facilities audited
Effectiveness Review Protocol
CAPA closures written to survive a second inspection. Verification criteria embedded at creation, not appended at close.
100%
CAPA closure rate
Mock 483 Response
Full narrative response drafted against the most probable observations for your facility class. Reviewed by a former FDA investigator before submission.
→ Delivered in 48 hours
GMP Training Remediation
Training record gaps closed with competency-based verification. Role-specific curricula tied to current SOPs and audit observations.
72 hrs
avg training gap closure
Annual Product Review

483 Response & Remediation"We received a seven-item 483 on a Friday afternoon. RegulatoryReady had a full response framework on our desks by Sunday morning. The investigator accepted every CAPA as written."

Pre-Approval Inspection Prep"Our PAI was three weeks out and our SMF hadn't been updated in two years. The gap assessment alone saved us from what would have been a complete shut-down scenario."

batch deviations in Year 1
CDMO Commercial Scale-Up"Scaling from Phase 2 to commercial at a CDMO without a single batch deviation requires a quality system that's been stress-tested before the FDA arrives. That's exactly what we built."

Tell us where you are.
We'll tell you what comes next.
A readiness call is 30 minutes. We review your current regulatory situation, identify the three highest-risk gaps, and outline what a scoped engagement would look like. No obligation. No generic proposal.
You describe your current situation — inspection date, outstanding observations, or scale-up timeline.
We identify your highest-risk gaps against current FDA enforcement trends.
We outline a scoped engagement with named deliverables and a realistic timeline.
