This research presents the validation of a Questionnaire-type Measurement Instrument (MI) through expert judgment, the IM was designed from the identification of criteria or factors through a Systematic Literature Review, determining 54 factors, same as they were discriminated with the application of Meta-Analysis, reducing to 29 factors, applied in the items. Subsequently, a group of five professional experts in Work Teams and Six Sigma evaluated the questionnaire on two criteria: quality and coherence. The empirical results show that, on a scale from one to four, 52.6% of the items were evaluated with a grade of four. Subsequently, through Friedman's statistical analysis, the disagreement was confirmed for the two criteria evaluated; Due to this, the measurement instrument was reviewed, improved and applied to a group of four different experts from the first group, repeating the Friedman test and obtaining a P value greater than 0.05 in the second evaluation, concluding that there is agreement between the experts. the 29 items of the IM and that it is valid (adequate) so that its application can be continued.
