I just got a copy of the book "Universal Methods of Design" by Bella Martin and Bruce Hanington. It is a book that presents a collection of 100 design methods. Each method is presented in brief and clear way on two pages with great images and graphics. Each methods is categorized in a straightforward and simple way for when during the design process it might fit and for what aspect of design. The explanations of each method are short, to the point and instructive. I find this to be an excellent handbook of design methods. The authors takes a great position in relation to methods. They write
This is an excellent approach. Methods are only means to an end, they are to be used intentionally. Measure of success are to be constructed by the user of the method. It forces each method user to take responsibility for the choice of methods. It is all good. Recommended!
