Measurement system analysis (MSA) uses statistical tools to determine the amount of total variation in a measurement system.It defines methods to assess the validity of a measurement system and minimize variation that couldAi?? contribute . to the variation in theAi?? process data.
The purpose of MSA is to validation that the measurement used to collect the product and process data is valid. The goal is to quantify the equipment/process variation, operator variation and method variation and the total measurement system variation.data.
The following areas components of measurement error needs to be studied and quantified before establishing capability of a process making decisions from the data.
