Defensible:
AI in professions where being wrong matters.
Most advice about generative AI is written for low-risk work, where a mistake is inconvenient but not consequential.
This book is for everyone else.
It is for engineers, designers, clinicians, lawyers, accountants, directors, consultants and other professional advisers whose work has to withstand scrutiny. In these fields, a wrong answer can affect people, projects, money, safety, rights, reputations and trust.
And someone has to put their name to the outcome.
Defensible sets out a practical framework for using AI in professional services and high-trust advisory work. It shows how firms can move beyond casual experimentation and build AI into workflows in a way that can stand up to review, audit, challenge or investigation.
At the centre of the book is the ENSOR Ladder.
A clear framework for deciding when AI should be used, how outputs should be checked, who is accountable, and what governance is needed before AI-assisted work becomes a professional deliverable.
AI is not just about doing things quickly, it is about doing things safely.
