• Operator falls asleep• Power Surges• Broken tool• Traffic due to snow• New, unanticipated, emergent or
previously neglected phenomena within the system;
• Variation inherently unpredictable, even probabilistically;
Special-cause variation always arrives as a surprise. It is the signal within a system.
