An example of what people are saying re: instructions being difficult.
For a job, I design computer systems and have a team of guys who work for me. One of the chaps who works for me is a technical writer, which is just a fancy word for saying "the lady who writes the instructions" but there is a bit more to it than just that.
When I first set up the team, I thought this would be an easy role to fill, but it has been the hardest of any of them. In the course of three years, I've had 5 technical writers, all with supposedly good backgrounds on their CV's, but the first 4 were, to be frank, useless. For a while I just put it down to general stupidity, but then I had a go myself, and found it exceptionally difficult. It would seem that some people just can't write good instructions, and other people can. And even if you instinctively can, it still takes a lot of practise.
I have found that if I seperate my tech writer from the rest of the project, results get better. That way, they haven't been involved in the "nuts and bolts" of the project while it was being designed and built, and so when they come to write instructions, they ask the same questions, and want to know the same things as someone who has just picked up the instruction manual and they don't subconciously assume knowledge becuase they have been involved with something for months.
I have a feeling though, that most places which product boat kits don't have the luxury of employing someone just to write instructions. i wonder though if they couldn't find time to dish the instructions out to friends and see what they think.
