The methods outlined below include philosophical, conceptual, pedagogical, visual (aesthetic), technical, categorical, and ownership. The last one, ownership, feels a bit odd because it’s not quite parallel to the rest of the bunch. I like a system that has a nice balance and this one has a slight imbalance. Happily, this slightly odd fit serves to emphasize the importance of allowing for an outlier. The outlier will cause you to reconsider your system every time—and that’s a good thing. The outlier is the thing that keeps your badge system honest, keeps it moving and evolving. Because if you’re designing a system so as to keep everyone within a certain range, you’re trying too hard. And you’re deep in the midst of a lush forest.
In any case, I’m curious to hear your reaction to these potential sorting efforts. No doubt these groupings can intermixed and most certainly they can be layered, possibly interleaved with one another.
