Thanks for the reply, rewt. Yes, that has helped clear the mists somewhat. So, to use a very simplistic example then. If I have a bed, chair and guitar stand, part 1) would be where I'd look at each object in turn and critique, say, the design, assembly method, materials etc and part 2) would be the main area of review, where I'd use analysis to synthesise, for example, that all three are used for resting things on but only two would be suitable for humans, even though the materials used in all three were quite robust and that the only one both a human and guitar could lie, sit rest on, would be the bed. Is that more or less the gist?
Thanks
