Determinação antecipada de falhas: complemento ao FMEA na análise da confiabilidade de produtos

Abstract

Currently companies are developing new methodologies and more often using quality tools such as competitive strategy during the product development process to improve results and reduce failures of their products. The aim of this study was to determine possible failures identified in the application of FMEA in a multinational company and explore the use of AFD tool to anticipate these possible failures and the resolution thereof. Was initially performed an analysis of two cases of failures identified after the release of the products although previously analyzed by FMEA tool during the development process. In a second step it was checked whether the AFD tool would be able to bring differentiated alternative resolution or prevention of the problems raised during the development of two products launched by the company. Both methods are effective in the item to show the problems the project team, however for the FMEA, the possibility of misuse of the tool and the wrong period of the product development cycle can mask potential failures. Thus, the AFD, the scanning characteristic of the fault, may be a value to the FMEA complement the analysis of major faults and reduced application time enabling the improvement of quality of the product during its development.
