Decision diagrams

My suburb has a charity second hand bookshop.

Today I found -

The Decision Book by Krigerus & Tschäppeler (ISBN 978 1 84668 395 4).
Some of the models in it would have been useful to me long ago:
E.g. The Eisenhower Matrix - How to work more efficiency.
Some are useful to me now:
E.g. The Black Swan Model - Why your experiences don't make you any wiser.

As an engineer I love the diagrams.
As an Australian I object to the meaning attributed to the expression "black swan" - black swans are very common around here.
