Green Belt Chapter 13: Measure Phase

Question 1

Failure Modes and Effect Analysis

Answer 1

A huge column table with numbered calculations that will help you list out the possible failures and the risks associated with a potential failure in the process to the customer.

Question 2

Collecting Data

Answer 2

Collecting data- it is needed in this phase to collect data and create baseline measurements. Hopefully there are already calculated metrics or there needs to be process monitoring.

Question 3

Continous Versus Discrete Data

Answer 3

Discrete Data: categorical (ordinal, nominal, binary, and attribute data)

Continuous Data: quantitative data with rank and infinite values (hrs per day, temp in degrees, length)

Question 4

Levels of Data (lowest-highest)

Answer 4

nominal data- applies number labels to a qualitative description.

ordinal data- the data is nominal but has ranking associated with it (pain severity 1-10)

interval data- there is meaning associated with the changes in the steps of the data, but no ranking.

ratio data- has the highest ranking where there is an absolute zero point.

Question 5

Choosing the Best Measurement Systems

Answer 5

goal of a measurement system is accuracy.
-a collector should have a booklet on how to accurately collect the data.

-use 10-bucket rule for accuracy

Question 6

Gage R&R

Answer 6

Gaging Repeatability & Reproducibility:
repeatability- can one sample tester come up with the same measurements over and over again?

reproducibility- can multiple sample testers come up with the same measurements over and over again?

Question 7

Collecting Data

Answer 7

Data Samples are collected as such:

• Simple Random Sampling
• Stratified Sampling
• Sequential Sampling

Question 8

Measure Tollgate Checklist

Answer 8

Things to do before moving from “Measure Phase:”
1.) Team has agreed on a measurement + created a baseline measurement

2. ) analyzed there chosen measurement and tested for reproducibility +repeatability
3. )The team has removed error risks from measurement systems.
4. ) The team has calculated the Sigma levels + variation levels
5. ) sampling has been done in a respectable way to create baseline measurements
6. ) the sponsor/champion has signed off on the measurement phase.
