Grid computing is a major research area with increasing impact on the business world. Substantial work has been spend on improving the grid middleware but the gap between the high expectations and available real-life grid applications is still remarkable. There is a significant emerging risk of creating a new hype which may result in disillusion and disappointment. Therefore, this paper emphasises the urgence of providing reliable grid-based solutions -- regardless of their scientific or commercial domain - in order to get grid computing to a mature state with wide-spread acceptance. An application prototype for editing and modelling grid workflows for semi-professionals - as part of an approach for solving this problem - and a grid job example are described.
