Operating Under Uncertainty

The plan seemed solid. Then something changed.

A new tool, a reorganisation, a result nobody expected. You are experienced and competent - and suddenly unsure how to move.

For a surgeon, that moment is not an exception. It is the job: deciding with incomplete information, acting, noticing when the situation no longer matches the plan, and changing course without losing control. Surgery never eliminated uncertainty. It built a method for working inside it.

Operating Under Uncertainty translates that method for any profession in transition. Drawing on years of surgical practice and a career in digital health and artificial intelligence, Ana Pina turns the habits of the operating theatre into tools you can use the week you read them:

• The unseen preparation - building the base before you need it
• The anatomy of fear - naming what you are actually afraid of losing
• Small trials - testing change without betting everything
• Reading the signals - the test result is not the patient
• Deciding to act - the checklist before the incision
• Damage control - what to do when things go off course
• A Navigation Map that assembles the entire method in one place

One method, complete. Instead of a separate book for each piece - deciding, fear, practice, experimentation, crisis - you get the whole sequence as it actually works in the operating theatre, from preparation to recovery, with the research that supports it referenced along the way.

Prompted by AI. Not about AI. This book was written because artificial intelligence made the ground shift under every profession, including the author's. What it teaches applies to any change that arrives faster than your plan.

For professionals, managers and teams who need to keep deciding, acting and learning - without knowing everything they will find along the way.
