The complexity of office software is increasing continuously. It is supposed that problems of usage and error probabilities are increasing as a result of this development. In an experiment the effect of complexity in a text editing system and the expertise of users on errors was investigated. Because of little practice and knowledge it was supposed that errors are more probable for novices than for expert users as a result of complexity. Results of our investigation show that complexity per se does not lead to higher error frequencies. Only for computer novices more mistakes and inefficient usage due to complexity were registered. The interaction of expertise and complexity is significant as well. it is concluded that broad functionality is not a quality criterion of software-systems by itself, bur that it might lead to excessive complexity and higher risk for errors as well as inefficient usage of software-systems in the case of novice users.
