I don't find that very fun.....it takes time that is better spent doing other things. I like Magpie's idea a whole bunch better (just a mechanic's opinion).
for many years I never found it a problem, I am one of those people blessed (or cursed?) with an almost photographic memory, I never had a problem identifying parts from my variuos cars, or putting them back in the right order.
Unfortunately as I get older I'm finding the memory isn't what I remember it being
So recently I've tended toward the Magpie way of thinking
I'm still OK wth my cars, I've had them for so long, I'm almost at US Marine stage with them, where I can strip and reassemble them blindfold.
But new stuff, I photograph everything before I start on it, and I label everything if there is going to be a delay before it goes back together.
My old foreman, back when I was an apprentice engineer, was a budding artist. He decided to paint a watercolour illustration of every stage during the stripdown and reassembly of his Rover P5. The restoration took him over 12 years as a result
The build record he ended up with however, is to this day one of the most stunning pieces of work I personally have ever seen
