MSA stands for Measurement System Analysis.
MSA helps to understand the sources of variation that influence the measurement result produced by the measurement system.
MSA is one of the very important core tools of the IATF 16949:2016 standard and widely used in Statistical Process Control and problem-solving tools like 8D, and Six Sigma-DMAIC methodologies.
The five IATF Core Tools are:
- APQP-Advanced Product Quality Planning
- FMEA- Failure Mode Effect Analysis
- PPAP-Production Part Approval Process
- MSA-Measurement System Analysis
- SPC-Statistical Process Control
MSA core tool is a part of APQP planning and one of the important document of the production planning approval process (PPAP).

MSA Meaning | Definition | Purpose
MSA primarily deals with investigating/analyzing the effect of the measurement system on the measured value.
Let’s understand the meaning of important terms used in the MSA quality core tool.
Measurement is defined as the assignment of numbers to material things to represent the relationship with respect to particular properties.
The measurement system is the collection of operations, Gages, and Equipment, Environment and personnel used to assign a number to the characteristic being measured.
The measurement process should be viewed as a manufacturing process that produces numbers (data) for its output.
Measurement System analysis study is carried out to determine the amount of variation or error present in the collected/measurement data due to measurement system.
No two things are alike in the world, there may be some variation. Variation is the law of nature and it can’t be eliminated but reduce to a controllable limit to achieve desired results.
The major sources of variation are broadly classified into two categories:
- Measurement System Variation-MSV.
- Manufacturing Process variation-MPV.
MSA’s purpose is to find the Measurement System Variation only.
It is very important to note that MSV should always be smaller than MPV (MSV The measurement system variations mainly focus on two important factors: In the measurement system analysis, the Gage R&R study tool is conducted to find out the equipment variation and appraiser variation. MSA classified into 2 types of distributions: >Explore measurement system variations. The objective of MSA in Quality or Measurement Process is to: PRODUCT CONTROL PROCESS CONTROL To measure the inside diameter of a cylindrical hole, we use a system that Includes: As a result of the activity, we generate a numerical value that represents the diameter.
