How they connect

Advisory sets direction. Delivery turns it into operating reality. The Lab develops the applied intelligence that informs both.

02 / Practices · Pillars I & II

Clear direction.
Accountable delivery.

Six focused practices across
advisory and execution.

Pillar I / Advisory & Transformation

03 / The 4D approach

How I lead
transformation.

My practical method: establish the facts, agree the plan, verify readiness and transfer ownership.

PHASE 014D / TDC DIGITAL ADVISORY

Discover.

What is actually blocking progress?

I check the plan against the reality: system readiness, unresolved decisions and the people who can enable or block change. Together, we identify which gaps matter most and who needs to resolve them.

What you getA prioritized risk and readiness assessment, with stakeholders and decision gaps mapped.
PHASE 024D / TDC DIGITAL ADVISORY

Design.

Who does what, in which order?

I turn the findings into a delivery plan: dependencies, decision owners and acceptance criteria. We work through legacy constraints and regulatory requirements before fixing the sequence, so the roadmap reflects what the organization can actually deliver.

What you getAn agreed roadmap with responsibilities, dependencies and risk mitigation actions.
PHASE 034D / TDC DIGITAL ADVISORY

Deliver.

What proves we are ready to go live?

I coordinate delivery against agreed checkpoints, escalate blockers and check the evidence behind reported progress. Testing and cutover rehearsals show what works, what remains open and which risks need a decision before go-live.

What you getTest results, a rehearsed cutover plan and an explicit view of remaining go-live risks.
PHASE 044D / TDC DIGITAL ADVISORY

Drive.

Can your team run it without me?

Before handover, I establish who owns the service, decisions and ongoing improvement. I work with those owners on the routines, knowledge and measures they need to manage change after go-live.

What you getNamed operational owners, a knowledge transfer plan and agreed measures for ongoing performance.

Platform in development

Making sense of
complex health data.

TDC is developing a digital health platform to help individuals bring their health information, everyday observations and personal goals into one structured view.

Health information becomes more useful when it can be considered in context and over time. The Lab explores how AI can help people recognize relationships, understand changes and identify questions worth exploring further.

The planned workflow combines a structured intake with written or spoken input and tracking over time. The development challenge is to connect these inputs and explain the resulting observations in a way the individual can understand.

Discuss the platform

Planned user journey

  1. Build a personal picture

    Set goals and capture health information through structured questions, notes or voice.

  2. Follow change over time

    Connect observations across time and explore possible relationships in the data.

  3. Make the information understandable

    Present observations in context, so people can see what changed and what may need further attention.

05 / A personal commitment

Independent in thought.
Invested in the outcome.

I connect the strategic picture with the reality of delivery. The value lies in making both work together.

I work with leaders facing consequential technology and transformation decisions. My role is to structure complexity, make risks visible and create the conditions for credible execution.

TDC connects three distinct pillars: Advisory & Transformation, Delivery & Engineering, and the Intelligence Lab. The Lab is our independent applied-research program in human-centered digital health and personal intelligence.
