PMI lists Plus (positive attributes), Minus (negative attributes) and Interesting (interesting attributes) for a certain alternative and scores them.
Paired comparison is a technique which compares alternatives one to one in a tabular fashion. It is sometimes also used to compare criteria and calculate their weights. Alternatives are set-up over both table axes. When comparing one alternative with another, one can give a preference over one idea to another.
Negative Selection sorts alternatives into ‘No’ and ‘Maybe’ to reduce a large number of alternatives. Use negative selection to select the best set of ideas quickly.
The NAF/NUF test scores alternatives based on their novelty, attractiveness or usefulness, and feasibility.
LCO evaluates alternatives based on Likes, Concerns and Opportunities, and uses opportunities as stimuli for ideation and further alternative development.
