Resumo:
The objective of this work was to implement Lean Thinking associated with BPMN to improve
the efficiency of the purchasing process of a Federal Institute. As a result, an increase in
efficiency and effectiveness in this environment was proven, through an increase in the value
delivered and a reduction in the amount of waste present. To achieve these goals, initially, an
analysis of the existing literature was carried out on what involves Lean Thinking, Efficiency
in Public Administration, Business Process Model and Notation and the use of Business Process
Model and Notation in the application of Lean Thinking concepts to increase efficiency in
Public Administration by reducing waste. From the standpoint of methodological procedures,
this research is classified as action research. Data were collected from the object of study
represented by the purchasing process of a campus of the Federal Institute of Education, Science
and Technology of São Paulo, using a questionnaire, informed and documentary techniques,
between the period 2019 and 2020. This work contributed, theoretically, with the scarce
literature on Lean Thinking applied to public administrative environments, and applied, first,
for a better identification of value specification by internal and external customers in the
purchasing process, allowing an improvement in the efficiency of its results, and, second, for a
reduction in the lead time of the purchasing process from 199.2 to 42.6 days, allowing an
improvement in the efficiency of its resources. Finally, a synergy between Lean Thinking and
the Business Process Model and Notation observed in the referred object of study of this
research should be highlighted
