The running ergonomist; a permanent appearance?

The title refers to the customary late consultation of ergonomists by engineers and designers when they have developed new products or systems. Why does this happen so late? Six examples from the author's career in which technology got too far ahead of ergonomics are described, necessitating the ergonomist to run behind. There were, and are, a number of causes for this lag. The engineer's and designer's overrating of the user's capacities in system operation is one of them. A contemplation of what has been accomplished by information ergonomics, also called user system interaction, up to the present day does not yield full satisfaction. Constant alertness and information provision by the ergonomist are necessary. Finally, a possibility to solve the described problems permanently is given.
