Not just to save money, but to make users happy.
Pictures, texts and colours are combined and optimised in keeping with the subject matter. This makes the instructions a whole lot more attractive, as well as very much simpler and enormously easier to understand. As the content is presented in a way the brain can easily absorb, you are likely to remember it for longer.
Structures and processes are graphically presented, making them intuitive and easy to grasp. The work of study is drastically reduced, and the processes are described transparently and without ambiguity.
Absolute concentration on the essential means that up to 90% of the original text can be dispensed with. This massive simplification also leads to massively lower translation costs.
