Step 2: Define Performance Standards
By the end of Step 2, the BB/GB will have:
a. Defined a defect.
What are the customer’s acceptance criteria for the part/product or process?
b. Established how to measure the quality of the part/product or process.
Where are the ing from?
How do you measure the process?
What are the units of measure?
Is it a discrete or continuous measure?
c. Determined the Performance Standard for their project.
d. Gained consensus with their team on the Performance Standard for their project.
Define Performance Standards Objectives
A Performance Standard is the requirement(s) or specification(s) imposed by the customer on a specific CTQ.
It answers the questions:
What does the customer want?
What is a good product/process?
What is a defect?
Some examples:
Blueprints
Sizes and dimensions are provided on parts
Contracts
Type of turbine, fuel efficiency, time of delivery, warranty information
Performance Standards
Establishing a Performance Standard
The goal of a performance standard is to translate the customer need into a measurable characteristic.
Operational Definition
Target
Specification Limits
Defect Definition
A characteristic should be measurable.
Translate the Voice of the Customer to the Voice of the Process.
Operational Definitions
Definition:
An operational definition is a precise description that tells how to get a value for the characteristic (CTQ) you are trying to measure. It includes “What Something Is” and “How to Measure It”
Purpose:
To Remo
