We learned this a long time ago...
IHI process improvement methodology originally developed by W. Edward Deming
What is PDCA (or PDSA)
This critical person/entity defines Value
Who is the patient/customer
You can manipulate a graph easily by changing the scale of these
What is axis'
If p is low, this must go!
What is the null hypothesis (aka Ho)
This statistical tool/calculation measures the relationship between two variables (and tells us storks bring babies)
What is correlation
Project tool named after a size of paper
What is an A3?
Acronym for the seven types of waste. AKA the highest paid person at M Health
Who/What is TIMWOOD
In order to use your data it needs to be in control, which is accomplished by this tool
What is standard work
This theorem allows those under 30 to hope for normality!
What is the central limit theorem
Of the two types of errors, this is the most concerning
What is alpha error
On the A3 document, it identifies what's being worked on, goal for improvement, and timeframe
What is the Aim Statement
It's OK to increase this type of activity
What is value added
Generally this is the minimum number of data points needed to begin assessing if a change occurred.
What is 30
Something is out of control if it's more than this many standard deviations from the mean in SPC
What is 3 standard deviations
Other than the process, variation can come from this
What is the measurement system
"Goal" metric that can't be directly controlled
What is an Outcome metric
Visual tool used to reduce inventory waste by controlling re-ordering of any supply
What is Kanban card
When assessing data it's not enough to look at the mean as patients/customers mainly feel this.
What is Variation/Standard Deviation/Variance, etc
These designate the voice of the customer
What is spec or specification limits
If more than ______% of your variation is from the measurements system you should not proceed with your project. Instead, work on improving the measurement system!
What 30% (accept 20-40%)
Visual tool used to define the scope (start and stop points) on your project
What is an Process Flow/Map (SIPOC, VSM, etc).
Lean tool used to visually highlight waste occurring in a space by controlling all aspects of the space
What is 5S
Statistical Process Control shows which two types of variation?
What is common cause and special cause variation
These designate voice of the process on a control chart
What are control limits
Rule of thumb- Relative to your average/mean, the standard deviation should be __________
What is less than half
