After COP 27 failed to agree further CO2 reductions, Professor John Dyson sat down to write an angry blog and then slept on it. What came back was a simple but powerful realisation: the environmental emergency doesn't require us to give things up. It requires us to find the 'ands'.

Before you design anything, you need to understand who values what – and why those values might conflict. Professor John Dyson introduces the value landscape: a structured way of mapping stakeholder needs that can reveal fundamental tensions in a project long before they become expensive problems.

The instinct to reach for certainty at the start of a project is almost universal – and almost always wrong. Professor John Dyson draws on Viktor Frankl and General Stockdale to argue that living with uncertainty is not a weakness but the precondition for genuinely valuable design.
