Sigma Chase

The quality behind the game

Every dot on the floor is a data point, and you can’t improve a process until you’ve collected the data. The four bell curves are variation in its different moods: one comes straight at you, one cuts you off, one wanders at random like common-cause variation, and one drifts the way a process mean does when nobody is watching.

The magnifying glass is the root cause, found. Once you have it, the variation flattens out and you can take it apart, but only for a while: on every floor the curves recover faster, the same way a fix that isn’t locked in fades.

Each floor you clear raises your sigma level, from 1σ to 6σ, or 3.4 defects per million opportunities.
