Avoid the (rather natural) mistake I made when creating cohort graphs.
Every business has table-stakes metrics that must be reported on but don't necessarily yield profound insights. Thankfully, you can gain a deeper understanding by faceting these reports into cohorts based on gamification. (Part two in a series on gamification measurement.)
What can measuring badge/level attainment teach you about the health of your gamification program? Moreover, how much better can your insights be using cohort analysis? Inquire within.
Gamification programs must be designed with flexibility in mind, else they're set up for extinction. To prevent that at a mechanical level, never award a single point for any activity. Here's why.
