Banking, healthcare, AI governance, operations, and institutional transformation. Different industries. Different technologies. Different symptoms.
In almost every case — a decision problem underneath. Who had authority. What the system was optimising for. Who owned the outcome. Whether anyone could reconstruct what happened.
If your regulator asked for a complete decision trail tomorrow — for any AI-driven outcome in the last 18 months — could you produce it?
Your AI systems are making thousands of decisions. Your governance was built for humans making dozens. That gap is where institutional risk now lives — and where we work.
A 10-day Decision Drift Audit. Eight layers mapped. One board-ready finding. No steering committee. No operational disruption.
Decision integrity doesn't slow your autonomous systems down. It gives your executive team the confidence to run them at full throttle.
Eight layers mapped. Three exposure points identified. One board-ready page delivered. No steering committee. No disruption to operations.
// Five things your board already feels. One structural cause.
Same logic. Different outcomes. Your team cannot explain why. A regulator can.
Each action stays within thresholds. The aggregate drifts into danger. SVB. The Gilt Crisis.
Dashboards stay green. The consequence arrives months later, unreconstructable.
Drift that took years at human speed takes hours at machine speed.
Everyone followed process. Nobody owned the outcome. The regulator is not interested in the distinction.
Most institutions have governance frameworks. Most have dashboards that show green.
None of that tells you whether the decisions can be reconstructed, challenged, or stopped.
That is the gap. That is what we map.
// The question to ask tomorrow morning
"Which decision made in this institution in the last 90 days could your team not fully replay today?"
Who authorised it. Which rules fired. What data was used.
"If the regulator asked for a decision trail from 18 months ago — how long would reconstruction take?"
SVB's answer was four months. By then it no longer mattered.
"When your AI model made 10,000 decisions last month — what was the boundary of its authority?"
If the answer is not in writing, it was not a boundary. It was an assumption.
If your governance committee cannot produce written answers to these questions — the audit has already begun. Start it deliberately →
// Three ways to engage — start wherever the problem is clearest
Decision Drift Audit
Eight layers mapped. Every gap between board intent and execution identified. Board-ready finding in 10 days.
Start the audit →Governance Interrogation
Structured working session with your board or ExCo. Three questions. Your institution's real cases. Written follow-up in 48 hours.
Request a briefing →Decision Architect Retainer
An independent practitioner embedded in your governance cycle. Board papers reviewed. Architecture designed. On-call advisory.
Request a briefing →All engagements are confidential from the first exchange. An NDA can be executed before any substantive discussion. Engagements are structured as fixed-fee, scoped at the kickoff session. · Full engagement details →
Three credit decisioning sequences — each individually within policy — could not be reconstructed end-to-end from available records. Two involved AI-assisted approval at L5 with no documented authority boundary. One had a gap at L6: the deployment decision that put the model into production had no retrievable authorisation record. Board remediation initiated within 30 days of the finding.
Composite case based on documented engagement patterns. Institution not identified. All findings anonymised.
// 01 · Diagnosis — what the data shows
To reconstruct the decision timeline after collapse. The data existed. The chain did not.
DIC™ L6 — no replay infrastructureA deployment decision made and executed. No verification record. No reachable kill switch. The institution could not prove what had been authorised at the moment trading began.
DIC™ L6 — no deployment decision recordPatient-facing deployment before independent validation. No traceable link between result and machine. The record that would have made it defensible was never built.
DIC™ L6 — no clinical deployment decision recordEvery LDI fund was individually compliant. No single decision wrong. No feedback loop at network scale.
DIC™ L8 — no cross-institutional feedbackOf total loss was amplification — not the original error. The error was recoverable. The inability to intervene in time was not.
This is the governance gap Decision Engineering™ closes.Most institutions can explain decisions. Few can replay them. The audit identifies which of yours cannot be reconstructed — in 10 days.
Start the audit →Each case is mapped in full through the DIC™ — the layer that broke, the decision that could not be stopped, and the structural change that would have prevented it. Not commentary. Architecture.
Read the six case autopsies →// 02 · Prescription — what needs to be intact
Most governance frameworks cover L1–L3. The failures above happened in L4–L8. That gap has a name.
// Decision Integrity Chain™ — all eight layers
Purpose. Strategy. Intent. Most institutions have these documented. Most boards believe they are enforced. The audit begins by verifying that assumption.
Rules. Judgment. Decision. Outcome. Feedback. This is where Knight Capital lost $440m in 45 minutes. Where SVB's decisions became unreconstructable. Where the board's intent disappeared.

// 03 · Treatment — how Decision Engineering™ helps
// How the audit reconstructs your decision chain — what it produces
All eight DIC™ layers mapped. Every gap between board intent and operational execution identified. Replay capability assessed. Board-ready findings in 10 days.
A structured working session with your board or ExCo. Three questions. Three layers. Real cases from your institution. Written follow-up within 48 hours.
An independent practitioner embedded in your governance cycle — not your politics. Board papers reviewed. Decision architecture designed. Governance questions answered as they arise.
// The typical engagement journey
Most institutions that commission the audit identify gaps they want to close systematically. The retainer is how that happens — an independent mind embedded in your governance cycle on a monthly basis.
// What happens in the first 30 days
60-minute session. You describe three decisions your institution made in the last 90 days. We identify which layers to examine.
Independent analysis of your governance documentation against all eight layers. No internal meetings. No disruption to operations.
90-minute briefing. One finding. Three exposure points. One recommendation the board can act on immediately — written for governance, not IT.
Most institutions identify gaps they want to close systematically. The retainer embeds an independent decision architect into your governance cycle monthly.
// What the 10-day Decision Drift Audit produces
Boards and senior executives commission this when they suspect the institution is executing correctly at the layer they can see — and drifting in the layers they cannot.
A structured walk through all eight DIC™ layers against your current operating model. Every gap named. Every exposure located. No generalities.
Not a risk register. A causal map — showing which decisions, if replayed today, would not be reconstructable by a regulator or an independent investigator.
One page. Written for the board, not the operating team. No jargon. Delivered within ten working days.
// The framework is practitioner-built. The research is independently verified.
// Institutions examined — all cited from public record, regulatory findings, and primary sources
// Eight published papers · SSRN Author ID 9450612
// Regulatory and policy context
// Research & Insights — the thinking behind the framework
Eight published papers on SSRN — co-distributed across 14 eJournals with authors from BIS, IMF, Federal Reserve Bank of New York, Harvard Law, LSE, Georgetown Law, and Cambridge. Top 10% of 2.74 million authors in six months. Three findings that underpin every engagement:
"Replayability — not explainability — is the governance standard for autonomous institutions."
"The gap between what an AI system optimises for and what the institution is obligated to protect is not a technology problem. It is a fiduciary one."
"When a protocol executes autonomously, the institution remains accountable. The infrastructure must be built for that accountability from the start."
// Built for institutional complexity — not theoretical environments
Built on 25+ years of driving cross-border business transformation, regulatory remediation, and high-velocity operations in environments where a single systemic error costs millions. This framework did not emerge from research. It was forged in the operational and governance environments where the failures described on this page actually happen.
Large-scale operating model redesign across regulatory boundaries. Multiple jurisdictions. High political and compliance stakes. Decisions that could not be undone.
Governance reconstruction under regulatory pressure. Working backwards through decision chains to establish what was authorised, what drifted, and what the record shows.
Institutions deploying autonomous decisioning at scale — where governance frameworks built for human-speed decisions are already failing in ways the dashboard does not yet show.
"The institutions that commission this work are not in crisis. They are the ones that have learned — from watching others — that the crisis arrives before the dashboard moves."
Not ready to start the audit yet?
One DIC™ layer per issue. One institutional failure. For boards and practitioners who suspect the dashboards are not telling the whole story. When you're ready to go further — the audit is one message away.
