What Is MSA Measurement System Analysis?

Mea­sure­ment Sys­tems Analy­sis, or MSA, is a sta­tis­ti­cal method to assess whether a mea­sure­ment sys­tem is suit­able for its intend­ed pur­pose. MSA helps us to rec­og­nize that total vari­a­tion is a sum of actu­al vari­a­tion of a prod­uct, process, or sys­tem and the mea­sure­ment sys­tem vari­a­tion. Unless we address vari­a­tion in the mea­sure­ment sys­tem itself, our attempts to improve process vari­a­tion will be inef­fec­tive. Learn the impor­tance of the five char­ac­ter­is­tics of a mea­sure­ment sys­tem and the dif­fer­ence between attribute and vari­able data MSA.
