Zero defect philosophy and 8D method applied to improve technical documentation of oil and gas segment suppliers

The present research has the general objective of developing a systematic procedure for reducing non-conformities in technical documentation from suppliers, allowing them to continuously improve their processes. Methodologically, the research was mostly supported by action research in a company in the oil and gas sector and its main suppliers. The conceptual basis of this research was supported by the philosophy 'Zero Defects' and the 'method of the eight disciplines - 8D' for problem-solving. As a result, a procedure was obtained that considers the union between these two methods (Zero Defects philosophy and the 8D method). In economic terms, the use of this procedure in the target company of this study generated a cost reduction of more than R$350,000.00 in two years of application. This result is due to the gains obtained by reducing costs related to documental non-conformities.
