Hodge Podge
100

This is the main focus of Lean

What is to eliminate waste?

100
This is the main focus of six sigma
What is reduction in variation?
100
This is the main purpose of the Define Phase
What is to get a thorough understanding of the problem and to establish the project scope?
100
This chart is used to rank categories in descending order
What is a pareto chart?
100

This is the shape in a process map that represents a decision point

What is a diamond?

200

The form of waste that happens when we machine 60 back up rings when the production order only called for 50 parts.

What is overproduction? (Will also give credit for 'inventory')

200
In six sigma, this is a symbol or another name for the inputs
What are X's?
200
This is the main purpose of the Measure phase
What is to understand the current state of the problem and ensure that the measurement system is reliable?
200
This chart simply plots data over time
What is a time series chart?
200

The type of data that has an infinite number of possible values within a selected range (example temperature, time, weight)

What is continuous data?

300

This is the main purpose of Poke Yoke

What is to prevent defects from occurring?

300
The number of defects you'd expect to see out of a million parts if a process had 6 sigma level quality
What is 3.4 defects?
300
By the conclusion of the Analyze Phase, you should be able to define these two key things:
What is the root cause of the problem and the hypothesis statement?
300
This graph is used to examine the shape and spread of sample data
What is a histogram?
300

These are the 3 factors in the risk priority number (RPN) which is used in a FMEA. hint: S X O X D = RPN

What are Severity, Occurrence, and Detection

400

This is the lean tool that is primarily focused on machine uptime and reliability

What is TPM (Total Productive Maintenance)

400
This is the methodology that we use in six sigma to resolve problems for existing processes
What is DMAIC?
400
This is the phase where we audit the process to ensure that our improvements are sustained
What is the Control phase?
400
This chart is used to illustrate the relationship between two variables by plotting one against the other
What is a scatterplot? (Alternate answer is 'regression analysis')
400

What is the purpose of a Cause and Effect (Fishbone) Diagram?

What is to identify potential root causes of a problem.

500

The names and sequential order of the 5 steps of 5S (Bonus: Also name the 6th 'S')

What is Sort, Set in Order, Shine, Standardize, and Sustain (bonus is Safety)

500
In six sigma, this metric is used to quantify the amount of variation or dispersion of a set of data values (it averages the distance of the individual observations from the mean)
What is standard deviation?
500

What is the primary goal of the Improve phase in DMAIC?

What is to test solutions and verify improvements (verify the hypothesis statement).

500
This tool is very similar to a histogram but it plots the data against specification limits and provides a Cpk value
What is capability analysis?
500

The four main questions that a good problem statement should address

What is What, When, Where, and How Big/Trend?
