Decision Library

A library of decisions worth arguing

Each page in this library takes one kind of business choice and sets out what usually settles it: the evidence that matters, the mistake people tend to make, and a worked example with real figures. They are written to be read before the meeting, while the choice is still open.

How the library is arranged

The broad pages cover a whole field of work, such as pricing, procurement, technology, security, operations and marketing. The paired pages take a single fork that returns again and again: building or buying, leasing or owning, one supplier or two, a lower price or a premium one. When your question is already a fork, open the paired page; when it is still taking shape, begin with the field.

Choosing where to begin

Start with the choice that commits money or time you cannot easily recover. A price can be revised next quarter, while a ten-year lease or a factory in another country cannot. Read that page first, then follow its links to the questions and use cases that sit beside it.

From a library page to your own room

These pages are public and general by design. Your own figures, deadlines and options belong in a Decision Room of your own, where each option is argued on its merits and the choice you make afterward is recorded as yours.
