Evaluation processes can range from the simple to the complex. The method
selected depends to some degree on the quantity and quality of ideas
generated. The number of ideas can run from less than a hundred to over a
thousand depending on the scope of the project. The first screening of the
list should be to eliminate the ones that obviously are of no use to the
project. However, each idea must be reviewed with a positive attitude. Look
for the good rather than the bad and do not be too critical.

The following process is suggested for initial screening.
Step 1: Each item on the idea generation form will be read. Each team
member will vote whether to keep the idea for future evaluation or drop
it. This is an impulse decision. Each person will decide by his or her
initial reaction as to whether to keep the idea or drop it. However, if one
person on the team wants to keep the idea, it must be kept on the list
without question. During this initial screening, there should be no dis-
cussion of the idea; only a yes or no vote is acceptable. The result will
be elimination of the obviously impractical ideas for this project.
Step 2: Then each of the remaining items on the list will be read, and
the group will discuss each idea. Table 7.13 can be used as a template
for this step. The intent is to determine what there is about each idea
that may be useful and decide whether to keep it on the list or to drop
it. It will be found that at this stage many ideas will combine with
