PMI By Post

PMI by Post.

I’m not a qualified lateral thinker, but for some reason I;ve always liked the sound of the PMI tool.
Taking time out to list the Plus, Minus and Interesting points before coming to a decision almost seems like common sense to me!
However I find it quite hard to shift in a few minutes from one attitude to the next and stick to it - keep jumping back to plusses when I should be doing negatives ! Also spend time wondering if that plus is only just interesting and vice versa.
So I was wondering – for community internet use especially – if it might be an idea to stick to one at a time and have a cut-off time.
Ie Just do pluses for say a week, then do negatives for a week, and then do interesting ?

After that points could be garnered, positives accentuated, negatives dealt with and fairy dust sprinkled over the interesting.
Or would that defeat the purpose ?
Any thoughts ?
