Thanks for those of you who have completed the survey and given me feedback
I should have probably explained a bit better in the first post.
I do realise that the subject of human error is very very complex, through all my research I keep discovering how much more it covers than I originally thought.
However because I'm an undergraduate I have been told to take a far simpler view, in fact I realise that at most I will only scratch the surface.
The aim of the questionnaire really is to find out about what people feel are key pieces of technology, both at the current time and in the future. I can then use these results to justify case studies in the dissertation.
This survey forms a small part of my research, and that's why its not 10 pages long or in-depth, I just wanted to make something that would only take people a few minutes tops to complete
Thanks again
Chris
