The Shelf

What I actually recommend.

People ask what to read, which frameworks to steal, and which tools survived contact with real operating. This page is the honest answer, kept short on purpose. If it's here, I've used it. Updated as my answers change.

Books

Five that shaped the operating years

Not a reading list — a working shelf. Each earned its place in a specific situation.

On execution

The Effective Executive — Peter Drucker

The book I reread before every new operating role. Drucker's question — what needs to be done, rather than what do I want to do — is the discipline underneath every turnaround I have run.

On decisions

Working Backwards — Colin Bryar & Bill Carr

The best public documentation of one-way-door versus two-way-door decisions, written by people who ran the mechanism rather than admired it. My essay on one-way doors argues with this book as much as it borrows from it.

On markets

Crossing the Chasm — Geoffrey Moore

Still the clearest account of why the technology adoption curve breaks companies. In MedTech the chasm has a reimbursement code attached, which is where my predicates essay picks up.

On capital

The Outsiders — William Thorndike

Eight CEOs judged by capital allocation instead of charisma. The title coincidence is real but so is the argument: the operators who compound are the ones the industry did not see coming.

On evidence

The Checklist Manifesto — Atul Gawande

Medicine's answer to complexity is humility plus structure. Every data room I build is downstream of this book's argument that expertise fails without scaffolding.

Frameworks

Four I reach for weekly

Mine and borrowed. The full versions live on the Frameworks page; these are the ones that earn their keep.

Mine

The Ninety-Day Data Moat Test

If your team stopped touching the product for ninety days, would it still get better on its own? One question that separates a compounding asset from a photograph. From The Data Moat Nobody Has.

Mine

The Four Tests of an Analogy

You are rarely talking to the decision maker; you are talking to the person who has to retell your argument without you in the room. Four tests for whether the retelling survives. From What Survives the Retelling.

Borrowed · Amazon

One-Way vs Two-Way Doors

Reversible decisions deserve speed; irreversible ones deserve the meeting. The single best filter for when “move fast” stops being good advice.

Borrowed · APACHE

Score What You Can, Judge the Rest

My first job was building the APACHE Score's data pipeline at GWU. The lesson has held for four decades: quantify the quantifiable so that judgment gets spent only where it is scarce.

Reading the industry

Where I actually get signal

The short list that survived unsubscribing from everything else.

MedTech

MedTech Dive + LSI Market Reports

The daily wire for device commercialization, and the conference intelligence that actually reflects what strategics are buying.

Capital

Bessemer's State of Health Tech

The annual read on where healthcare capital is moving, written by people who deploy it. I test my own Series B assumptions against it.

AI

Stanford HAI · AI Index

The one AI report I trust on capability trends, because it is measured rather than marketed. Most of my discipline-gap arguments cite its data.

Clinical

JACC: Cardiovascular Interventions

Where interventional cardiology actually argues with itself. If a claim about the cath lab does not survive this journal, it does not go in my writing.
