Thinking in Systems

Why your fixes don't stick, why reasoning needs to be visible, and the method that connects them. A series in three parts.

Thinking in Systems

A series in three parts

Almost every organisation is busy. Rather fewer are getting anywhere. This is about the difference โ€” and about a way of thinking, invented for factories, that turns out to apply to almost anything you are responsible for.

Each part is a scrolling piece: the drawings build as you read. Best on a reasonably wide screen.


Part one ยท The Wrong Queue

A clinic where sixty people are waiting and everybody knows where the problem is. They are all wrong โ€” and what they get wrong is the most reliably counterintuitive thing about how systems behave.


Part two ยท The Arrows Nobody Checks

Five intelligent people, five confident and incompatible answers. Why arguing doesn't settle it, why most diagrams are decoration, and the eight questions that turn a picture into an argument.


Part three ยท Five Shapes

The method itself: five questions any real change has to answer, the differently shaped answers they need, and why its author quietly retired one of his own tools.
