// Advisory work · Independent practice
Three engagements. Each one begins with a structured examination of the decision chain — not a technology review, not a process audit. A structural governance interrogation.
// The practitioner behind the framework
25 years · FSI and healthcare
Global banks. Global insurers. Financial market infrastructure. Institutional transformation across all major global markets. Market building across 12 countries in Asia. CXO-level healthcare transformation. Regulatory engagement across 25+ jurisdictions.
Two named outcomes
Global bank liquidity transformation — revenue rank up 3 positions in two years. Global insurer continental digitisation — consistent architecture across multiple countries, multiple languages, multiple regulatory environments.

01 · 10-day engagement
Map your institution's decision chain against the DIC™. Find every layer where intent, rules, and execution have diverged. Deliver a board-ready architecture map and finding — not a 300-page report.
02 · Board session
A structured half-day session with the board or executive committee. Not a presentation — a working session. Three questions. Three layers. Every one designed to surface what the dashboards cannot show.
03 · Ongoing advisory
Monthly engagement. Governance questions as they arise. Board papers reviewed. Decision architecture designed. An independent practitioner embedded in your governance cycle — not in your politics.
// Who this work is for
High-consequence institutions where the chain from board intent to operational outcome has grown longer, faster, and more automated than governance has kept up with.
"By the time a board sees decision drift, it has usually been operating for 18–36 months."
"If you cannot reconstruct a decision end-to-end — you don't have governance. You have faith."
"The question is not whether the AI is right. The question is whether the institution can govern what it has built."
// Start the conversation
Every engagement begins the same way: one question about a decision your board cannot fully reconstruct. What happens next is structured, confidential, and specific to your institution.
A loan portfolio shift, a model deployment, a board-approved initiative — where the outcome does not match the intent. You want to understand exactly where the chain broke.
Not yet ready to name the specific decision. You want a confidential introductory conversation — under NDA — to understand what the audit involves and whether it applies to your institution.
