RESUMO:

The management philosophies evolution occurred based on the need to achieve high
performance of effectiveness and efficiency of productive systems of goods or services.
Specifically for operational management, changes in strategic management as well as
interferences due to unexpected events or needs for rapid changes in the operational
context directly affect production quality and, consequently, generate disturbances in
processes resulting in a negative impact on planning, control and production scheduling.
Among other parameters that impact operational management, the production time
variability generates a greater impact to achieve the expected results. Time variability
causes disturbances in production systems, presenting problems such as unbalance of the
production line, product defects, equipment breakdown, among others. This study proposes
to analyze the impact of time variability on the organization’s performance, inserting
in the decision-making model a framework that analyzes in real time the variability of
production time and the impact on the organization’s performance dimensions . A system
for collecting, organizing, analyzing and interpreting the variability of production time
is proposed, integrating an analysis of the impact of variability on the dimensions of
economic, social and environmental performance. The framework was developed based
on an exploratory data analysis for the statistical characterization of process, process
variability control through a control chart method and, finally, analysis of the impact on
performance dimensions. The analysis of the impact of time variability on performance
dimensions is carried out in two stages of validation. The analysis of time variability is
presented in real time by means of control charts, identifying the variability of the process
and, subsequently, the impact on the performance dimensions analyzed. In addition, a
collaborative performance indicator is presented for all analyzed processes. In the first
validation, the support system demonstrates that the management of time variability has a
greater impact on the productivity dimension, with little impact on the quality dimension.
In the second validation, referring to sustainability, the economic impact prevails over the
social and environmental dimensions. The impact on the social dimension showed great
variability, that is, the decision-making model of operational managers generates great
variations in the social dimension resulting in negative results for the organization.
