The following paper presents results from a longitudinal study about the importance and use of information and communication technology in Swiss small and medium-sized companies. In an empirical survey, 989 questionnaires were collected and analysed (return rate 17 %). The results were weighted according to company size and industry sector and are thus representative for Switzerland. The findings show that Swiss SMEs – in their self assessment – manage to gain (competitive) advantages from the deployment of information and communication technology. ICT is universally used (even) in (small and medium-sized) companies. There is a high degree of inter-organisational ICT use. ICT know-how and awareness are strongly rooted in management. The general conclusion is that IT matters for Swiss SMEs.
