Infrastructure & resilience
A communications outage at Philadelphia follows a documented upgrade programme. The ABT question: what did the correction cover, what was tested, and is that evidence still current?

An airport bathroom is a deceptively simple system. When a lock breaks, can the organisation detect the problem, verify it and correct it before the next traveller arrives?
Institutions fail in the same way. Not because problems are invisible, but because detection does not reliably lead to correction.
The Airport Bathroom Test reveals where that correction chain breaks.
Mapped to Time × Trust × Cooperation
What will you learn?
You will receive a resilience score across Time, Trust and Cooperation, plus the weakest link in your correction chain.
The book
Why Strong Systems Break and What Builders Do Differently
We have spent decades improving detection. The next challenge is correction.
Organisations now produce more alerts, audits, dashboards, risk reports and early-warning indicators than ever before. Yet obvious failures often remain unresolved.
A broken tap can reveal how an entire organisation works. The Airport Bathroom Test follows that question from everyday services to financial markets and public institutions, exploring how time, trust and cooperation shape the ability to put things right.
The core framework
- ▸ Time
- ▸ Trust
- ▸ Cooperation
Key ideas developed in the book
- · The correction chain
- · The Zero Factor
- · Institutional rhythm
What happens when a system sees the problem, but still cannot act?
Resilience is not the absence of failure. It is the capacity to detect, verify and correct failure before the system loses its rhythm.
Praise for the book
“A clear, usable lens for anyone who must turn long-term commitments into credible action.”
“This book deserves to be widely read.”
