Cpk 0.5 aka Sigma level 1.5 (at best)
Re-inventing the wheel…

• A “bad process”
• Not very capable of producing the results you want
• Lots of “width” & little space
• High risk for patient to have > 240 min
• Typical sigma level for healthcare processes

How capable is the process? • A “good process”
• Very capable of producing the results you want
• Little “width” plenty of space
• Low risk for patient to have > 240 min
Number of Lean 6 Sigma studies is on the rise…

50% of payments tied to quality or
value…by 2018 (!)
“Value” = ???

2015/12/03/the-meaning-of-value-in-health-
care/
“Value” is defined as “the health outcomes per dollar spent.”
Value = Outcomes / Cost…& needs the VOC
“Cost” = ???
Sounds awesome! …and no one
does it.
Healthcare Value Process Index = (100) Cpk / COPQ*
*COPQ in thousands, eg $250,000 => 250…note the VOC
COPQ = $200,000; so HVPI = 0.1
COPQ = $125,000; so HVPI = 0.048
