Why invest into GUI design?
Good GUI design has, as a consequence, dramatic results in time spent on doing the work and reducing the number of errors. Surveys of different researchers indicate that, as a result of programme design in improvement, the average saving of time and error reduction is around 25%, although in the extreme cases it goes even up to 130%. In 2006, Nielsen wrote in his report to IBM that optimization of programmes used by them lead to a saving of 72 minutes a month per employee. In this way the company saved $194 million on annual basis. Good design leads to saving when staff training is concerned as well. There is a lower need for instructors, it is necessary to organize significantly training sessions, and the employees get used to the new programme dramatically faster. In 2001 IBM set a postulate of cost-efficiency of investing into programme development. For every $10 of good-quality investment into programmes enhancement, $100 turn up as a profit.
