I spent more than twenty years at Comcast, moving from frontline operations into executive leadership. My work often sat where organizational seams became visible: customer escalations, regulatory complaints, social media, privacy and security response, large-scale service operations, transformation, and the systems used to make decisions across teams.
Those years left me with a persistent question: why do capable organizations repeatedly struggle with problems they can already see?
The answer is rarely a lack of intelligence or effort. More often, information is fragmented, decision rights are unclear, and accountability weakens as work moves across teams and over time.
I describe those conditions through a framework called Coherence, built around three questions:
Truth: Is the information real, complete, and accessible?
Authority: Is it clear who has the right and responsibility to decide?
Continuity: Do decisions and commitments persist across time, systems, and organizational boundaries?
This publication is where I write about leadership, operating systems, AI, judgment, customer experience, and the quiet structural conditions that determine whether organizations can execute.
The Coherence Record contains developed essays and observations about organizational performance, responsibility, and change.
Open Garage documents the work of building and experimenting with AI systems on privately owned infrastructure, including what works, what breaks, and what the process reveals.
The Quiet Work focuses on the people and practices that hold organizations together but are rarely visible when success is celebrated.
I write when I have something worth examining, not to maintain a publishing schedule.
