Three proprietary methodologies for metadata, data warehouse, and data governance — refined across 155+ enterprise programs since 1997, and documented down to the narrative so they hold under cross-examination by boards, regulators, and auditors.
A methodology is only useful when it survives the org chart, satisfies the auditor, and shortens the calendar. Ours have done all three for nearly three decades.
When the CDO who sponsored the program moves on, M3, I3, and G3 stay. What was decided, why, and against which constraint is documented as a narrative — not held in tribal memory, not in someone’s inbox. Your next hire inherits a working program, not a forensic exercise.
2003 / 2002 / 2006 · Years M3, I3, G3 have been in continuous use.
Boards, regulators, and audit committees ask the same question in different words: who decided what, on what data, against which control. Every M3, I3, and G3 narrative captures decision context as the work is done — not bolted on six weeks before the audit. Methodologies designed for the FBI and the Mayo Clinic are built to satisfy scrutiny, not to survive it.
360+ · Documented narratives across the three methodology libraries.
Across 155+ client partner engagements, M3, I3, and G3 have already met the architectural decision, the data-quality compromise, and the governance escalation that will land on your desk this quarter. We are not learning on your dollar — we are applying a methodology refined at someone else’s scale and sequenced for predictable delivery: 35–60% faster, with up to 91% lower program cost vs. improvised builds.

David Marco has defined the discipline that organizations now rely on to govern their most critical data assets. His proprietary frameworks — M3, I3, and G3 — have shaped enterprise programs across federal agencies, academic medical centres, and Fortune 500 enterprises, including the FBI, the Mayo Clinic, UHG / Ingenix, and Harvard Pilgrim. He has provided executive oversight on all 155+ EWSolutions enterprise programs and personally led 30 of them.
M3, I3, and G3 are documented to hold under cross-examination — by boards, by regulators, and by audit committees. Each dossier below shows the years in continuous use, the engagements that shaped the methodology, and the executive who has said so on the record.
Delivery-acceleration figures are average outcomes observed across documented client engagements; actual results depend on scope and starting maturity.
The foundation layer for data lineage, business glossaries, and decision-grade data feeding AI — the layer that determines whether your model risk is explainable to the board.
Each M3 engagement adds one narrative to the library — what was decided, why, and against which constraint. The library is how the next program inherits the last one instead of starting from a blank deck. It is also how decisions remain defensible when the CDO who sponsored them moves on.
M3 codifies methods refined across David Marco’s advisory work for the Department of Defense, the FBI, and the FAA. David Marco has provided executive oversight on all 155+ EWSolutions enterprise programs and personally led 30 of them.
M3 has been applied where governance is tested in the open, not in the audit folder. Each engagement reinforces what the methodology must withstand before it is published as a narrative.
David Marco and his company EWSolutions have consistently delivered successful Data Warehouse and Metadata Management implementations for several decades.
The delivery methodology for analytic platforms shipped on calendars set by boards, not by vendors — with the architectural decisions documented as they are made.
I3 sequences delivery in milestones a board can defend — scope decisions, data-quality compromises, and architectural trade-offs are captured as they happen. The audit pack is a by-product of delivery, not an addendum prepared six weeks before review.
I3 is built to satisfy the board chair, the data steward, and the auditor in the same delivery — not to satisfy each in a separate document. The methodology assumes scrutiny from all three.
I3 has been applied in environments where the warehouse layer underwrites operational, regulatory, and clinical decisions — the kind of analytic foundation that is read by an auditor before it is read by an analyst.
EWSolutions’ methodology and expertise helped us to meet our stretch project goals ahead of schedule.
The operating model, stewardship structure, and accountability chain that hold when boards, regulators, and the market test them — designed in, not assigned later.
Ownership of data, of model risk, and of downstream consequences is assigned by design — not allocated after a consequence surfaces. G3 produces an operating model regulators expect to see and an accountability chain the board can follow without a translator.
G3 is the methodology behind every EWSolutions AI governance engagement, including responsible-AI operating models. It is governance built for the boardroom, not the audit folder — the same architecture that holds whether the scrutiny comes from a regulator, an auditor, or a journalist.
G3 has been deployed where governance must withstand cross-examination — from FOIA to FDA, from audit committee to Office of Inspector General. Each engagement extends the methodology’s defensibility surface.
EWSolutions provided a strong foundation from which to grow and transform our data to meaningful, useful, and collaborative information.
Recognized across data management, business intelligence, and innovation for two decades — with the Department of Defense citation as the earliest, and the BIG Innovation Award as the most recent.
A 30-minute Executive Diagnostic, scoped to your initiative — not to a sales script. We will tell you which methodology fits your problem (M3, I3, or G3), what a defensible timeline looks like, what artifacts your team would receive in the first 90 days, and what a no-go answer would mean.
No deck, no discovery call “to learn more.” Direct access to a senior advisor who has run programs at the FBI, the Mayo Clinic, Harvard Pilgrim, and UHG.
