Spent quite a bit of time deciding on the ranking algorithm for the new kanochart.com

This one is for the Kano nerds πŸ€“

Features are prioritized as follows:
- Features in the positive quadrant (the area enclosed by dashes) rank higher than the one outside the quadrant, even if their category is higher (see features ranked #1 and #4, where #2 and #3 are of a "lesser" category, but still fall within the positive quadrant);
- Then, feature category determines priority. Must > Perform > Attract > Indifferent > Reverse > Questionable. Features that fall in the latter two categories shouldn't be on your roadmap anyway; you should rethink them.
- Features in the same category are ranked according to their distance from the middle of the positive quadrant (x:Live With, y:Expect). #2 is a stronger Perform feature than #3 and therefore ranks higher.
