In the beginning, every designer makes a lot of mistakes. You never stop making them, in fact but they grow less in number as your experiences grows. Most are made in working out the design – in giving the abstract idea its concrete form. In my experience as a mistake maker, there are eight special ones which you have ti guard against. They are listed below:
4.3.1 The missing imperatives
4.3.2 The missing overview
4.3.3 The impracticality of a design
4.3.4 The-missing-melody
4.3.5 The non-integration problem
4.3.6 Some minor but critical faults
4.3.7 An always avoidable fault
4.3.8 A fundamental fault
