Measurement System Analysis (MSA) / Gauge R&R

When to use

Use this skill when:

• Qualifying a measurement system for a new part or process (PPAP requirement)
• Interpreting Gauge R&R results — is this gauge acceptable?
• Auditing a supplier's MSA study for correctness and adequacy
• Selecting the right study type for a given measurement situation
• Investigating a quality problem where measurement error may be a factor
• Responding to a customer request for MSA data on a specific characteristic

Prerequisites

• The characteristic to be measured (product or process)
• The gauge or measurement system to be studied
• Production parts spanning the expected process variation (10 parts minimum)
• At least 2 trained appraisers who normally perform the measurement
• The specification (tolerance) for the characteristic
