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.
