RESUMO

Background: Due to the growing need to better understand the organizational elements, subjective measurements are gaining more and more space. Problem: can we assess how reliable a data sample collected via 2-value subjective measurement is in relation to the reality of the attribute of a measurand? Hypotheses: Hypothesis 1 - there is already a scientific method that can effectively perform the assessment mentioned in the problem; Hypothesis 2 - in the even the first hypothesis is not met, it is possible to create a method that can effectively perform that assessment. Purpose: After confirming the absence of a scientifically established method that can perform the evaluation mentioned in the problem, the purpose is to develop a method to effectively perform that evaluation. Methods: Development of theoretical basis on the grounds of subjective measurements; literature review on existing methods that work with 2-value subjective measurement; development and validation of a new method that solves the problem proposed. Scope and limitations: the publications used to develop the theoretical framework of subjective measurements and the new method are multidisciplinary, yet the focus given to the studies was more related to organizational management, with emphasis on matters pertaining to Production Engineering and related fields. Results: (1) postulates on subjective measurements have been elaborated; (2) the main sources of subjective measurement errors based on those postulates have been outlined; (3) no scientific method or mathematical expression that may address the problem proposed has been found on the literature; (4) a method was developed to work with two-value subjective measurements. Analysis of results: (1) the postulates developed served as a basis for raising the main sources of subjective measurement errors; (2) the theoretical framework served as the basis for establishing the primary method that used two-value subjective measurements; (3) new studies allowed for the improvement of the primary method by developing the new method; (4) a case study showed the applicability of the new method. Conclusions: The studies have allowed us to effectiveness of the method for 2-value subjective measurements.
