A couple times in my life, I have made difficult life decisions using a spread sheet. Of course, I’ve also used this technique while working to help a group come to a consensus. The spreadsheet typically lists a series of criteria with a numeric weighting, and a score for each option. Total up the scores times the weightings and voila, you have your answer.
This would be a fun Web app to build, so that Excel wouldn’t be a prerequisite for ending personal paralysis. It would be a great collaborative app, so that a community could reach consensus, or contribute criteria, or arguments for and against each option. Decidr.com is taken, any other ideas?
