```Based on the work of Dr. Edward de Bono
The PMI method gives
deliberate attention to
exploring, first, the positives or
plus factors in the new idea.
The second operation
when using the PMI is
to look for negatives or
minus factors.
The third operation is to look
for the interesting
possibilities in the new idea.
Without exploring an idea for
possibilities or alternatives, a new idea
has only a 50/50 chance of survival.
Those considering it either like it or
dislike it. When the interesting
possibilities are explored, whatever our
view of the idea by adding to the plus
alternatives that give the idea more
chance of 'survival'.

IDEA ONE: By law all cars should be painted bright yellow.
IDEA TWO: People should wear badges showing whether they are
in a good mood or a bad mood that day.
IDEA THREE: Every adult should spend one week a year in the
police force.
IDEA FOUR: People should be allowed to work 10 hours a day for 4
days and have the rest of the week free, instead of
working 8 hours a day for 5 days.
