Sigma Siege
CONTROL LIMITS · SIGMA LEVELS · SPECIAL CAUSE
Defects descend on the process in rows of sigmas, bell curves, out-of-control points and crosses. Shoot them down before they cross the lower control limit, watch for the red special cause, and clear each wave to climb from one sigma to six. Plays with a keyboard or on a phone.
Root Cause Run
ROOT CAUSE · CONTROL CHARTS · PDCA · CAPABILITY
Red tags, out-of-control points, rework loops and skewed curves swoop in, form up and dive at your σ. The fishbone boss can capture your ship with its beam: shoot it to win the ship back and fire double. Catch the PDCA shield, the rapid-fire check mark and the Cpk bonus as they fall.
Sigma Chase
DATA COLLECTION · VARIATION · ROOT CAUSE
Steer your σ through the floor and collect every data point while four bell curves hunt you: one chases, one cuts you off, one wanders at random and one drifts like a shifting mean. Find a root cause and the curves flatten out, and then you can chase them.
