A GR&R study is an important tool that can help separate the components of variation in a measurement system. These components are the Operator's influence on the results, as well as the Instrument's influence on results. If the Reproducibility result was $5\%$ and the Repeatability result was $50\%,$ what would you recommend as the next step to improve this measurement system?

Re$-$examine and possibly re$-$vise the handling of the part to be measured as the interaction between operator and part is too high

More training for the operators

Do nothing, the measurement system is ready to proceed

An investigation into the instrument to validate it is operating correctly
