It depends -- a lot -- on the flowchart. Many of them are totally
useless. I've found them that direct you to compeltelyy the wrong area
(in at least one case, to an area of the system that couldn't possibly
cause the symptoms I was observing).
The problem with all 'expert systems' or whatever you want to call them
is extracting the date from the experts. Now, I am not an expert, but
I've repaired a few things, and I know I could not produce a repair
flowchart for any of the machiens I've worked on. No matter how well I
know them. There are a lot of things i observe when I am tracign a fualt
that I don';t realise I am observing.

I was once asked 'Don't you think
<foo> should be repaired by a trained
engineer'. My reply was 'No. I think it should be repaired by soembody
who actually understands how it should work and can find out what it is
actually doing. Not somebody who can just read and follow a manual'.
But the old follow-the-flowchart method really did work well, didn't it?
