Slide 12 of 17
Notes:
Can we use a control chart?
No, not controlled process - yet
There’s a pattern in the daily readings
That’s not random variation
Early on - high in morning, low at lunch, higher at dinner, and peaked at bedtime.
PDCA: Challenged doctor to split dosage in half - morning and dinner.
Result: Bedtime readings lower!
But we were able to start identifying special causes:
Stress (losing contract)
Missing meals
Missing medicine
Sickness
