Because of the demographic change and the rising number of computer workplaces, there is an increasing need for an age-robust software design. In the first part of this paper three basic studies with prototypical project management software applications are presented which lead to recommendations for an age differentiated design of the human-computer interface. In the second part, project planning with two commercial project management software tools was investigated regarding age differences in order to identify deficits in the de facto standard and derive inferences for further research.
