Idea ranking is a technique which ranks alternatives on intuition. It is especially useful if you have a larger number of decision alternatives and want to quickly select the most promising alternatives.

The first part of the Kepner Tregoe matrix is going through a normal Decision Matrix. Afterwards, the top 3 from this matrix is selected for analysis in the matrix shown just above.

LCO evaluates alternatives based on Likes, Concerns and Opportunities, and uses opportunities as stimuli for ideation and further alternative development.
