The requirements of measurement system analysis shall be initiated from product and process design and development when the product and process special characteristics shall be defined and documented for selection of measurement system. Both variable and attribute measurement system. 

1. The measurements system can be classified into variable and attribute measurement systems.    

2. The measurements systems can be a set of measurement equipments, appraisers, master samples or method of measurements.

3. The methods of measurements systems analysis shall be based on the impact of the variation of measurements systems to product characteristics.  

4. Attribute measurements system only based on error alarm system according to hypothesis Test Analyses and Signal Detection approach.

5. Variable measurement system is based on bias, linearity, gauge reproducibility and repeatability (GRR) shown on graphic.  

6. The training program for MSA is designed by laboratory engineer or consultant.
