PMI: THE TREATMENT OF IDEAS
P = Plus The good things about an idea - why you like it
M = Minus The bad things about an idea - why you don't like it.
I = Interest What you find interesting about an idea.
Instead of just saying that you like an idea, or don't like an idea, you can use a PMI.
When you use a PMI you give the good points first, then the bad points and then the points than are neither good nor bad but are interesting.
You can use a PMI as a way of treating ideas, suggestions and proposals.
