The Humm handbook

the long version

"Understanding human nature is a problem that people have been trying to solve throughout the ages. Almost everyone would like to have an understanding of the disposition of those about them so as to be able to predict their behaviour. This is particularly true for managers. Great managers have a strong desire to understand the temperament of their staff, peers and superiors. The Humm uses seven components that cover emotional behaviour. The secret of the Humm is to learn how to recognise the dominant components in other people and then you can tailor your management style accordingly."--Publisher's website.
