The Doyen Data Model™ is a self-hosted PHI data flow mapping and IT asset repository — cataloging every application, contract, project, data field, vendor, hardware profile, site, person, team, and interface in your healthcare organization. All of it searchable in seconds — at your desk or on your phone.
Applications organized across the patient journey — patient-data systems visually distinct from support systems — every flow between them tracked and searchable.
The interactive diagram organizes every application by patient-care phase — Pre-Registration through Post-Discharge — with a separate grid for infrastructure and support systems. Click any application, contract, project, hardware profile, person, team, or site to open a full detail sidebar.
A single query covers applications, data flows, contracts, projects, entities, hardware profiles, phases, data fields, project documents, departments, workflows, personnel, teams, vendors, certificates, and sites — each rendering as its own labeled results category.
Results are fully cross-referenced: a matched contract, project, or site lights up every application it touches on the diagram, not just what's directly tagged.
Trace any patient data field (SSN, MRN, Guarantor, Date of Birth, etc.) to every application and data flow that touches it. This is the definitive answer to: "what's exposed if this is compromised?"
Core fields aren't a guess at what matters — they're grounded in the identifier categories HIPAA's Safe Harbor de-identification method defines (45 CFR §164.514(b)(2)), reviewed against what your systems actually capture.
DDM™ now maps where everything runs — data centers, hospitals, clinics, and cloud or hosted environments. Hardware sits at a site, applications run on that hardware, and DDM connects the chain. Every site opens with an "Impact If Unavailable" summary: how many applications depend on it, how many handle patient data, and how much hardware is there.
Outages don't wait for you to get back to your desk. On a phone, DDM™ becomes a focused lookup app — search, results, and full-screen records with a Back button — and installs to the home screen like a native app, with no App Store involved.
DDM™ is not just a diagram — it's a full asset and relationship registry for the entire organization.
Four roles — Administrator, Senior Admin, Manager, and Analyst — each with genuine, enforced boundaries, not just a label. Records marked Restricted — contracts and sites — are invisible to anyone without access: not just hidden, but undiscoverable — no confirmation a restricted record even exists — enforced consistently across the web app, search, and DDM Plus.
DDM Plus adds a Claude-powered AI connector (MCP) that lets any authorized user query the entire platform by voice or text — no training required. Eight purpose-built tools cover every common investigation:
DDM Plus is licensed per the customer's existing Claude subscription — the AI cost never lands on shoëfware.
A real-time, attributable activity log that shows your team exactly how DDM is being used — searches, record views, and results, timestamped and tied to a real account. Full transparency, zero guesswork.
DDM™ is self-hosted — installed on your own infrastructure. shoëfware never touches your PHI data.
The full platform — visualization, search, field tracing, sites and infrastructure, contracts, vendors, certificates, projects, entities, hardware, personnel, teams and time commitments, attributes, mobile access, and the complete admin panel.
Everything in DDM, plus the Claude-powered AI connector — natural language and voice queries across all eight tool categories.
Search, field tracing, contracts, projects, and DDM Plus — all in one demo.
