In the context of this work, the transformation process towards quality of the petrophysics laboratory of the Center of Research in Geology and Geophysics (CPGG) of the Federal University of Bahia (UFBA), located in Salvador, Bahia (BA), Brazil, is presented. The quality system implemented in this laboratory was based on the norm ISO/IEC/EN 17025 (General Requirements for the Competence of Testing and Calibration Laboratories), which constituted a fundamental tool for the implementation. However, during the implementation process, some problems were encountered. This was going to be reflected in an excessive investment of time and money. It was possible to identify the causes that generate additional costs and delay the implementation process of the quality system ISO/IEC/EN 17025 in the petrophysics laboratory. This was done by using two of the basic quality control tools: the Cause-Effect diagram (Ishikawa or Bone fish) and the Pareto diagram. With the Cause-Effect diagram, the common and special causes of variation (six in total) were detected. As a result of the analysis with the Pareto diagram the relationships between problems and causes were found.
