Abstract

One of the techniques used to ensure product quality and reliability even in the design phase is the FMEA (Failure Modes and Effects Analysis) that, with preventive measures, seeks to mitigate the failure modes. However, some limitations of this tool restrict its application. As a result of these limitations, this study proposes a method that integrates the philosophy of A3 method and FMEA practices on a standard A3 document for fault analysis and recording of the knowledge generated. The study is applied in an industrial automation company whose production process is characterized by jobbing and aims to contribute in improving the process of analyzing faults and troubleshooting. This study is divided into three phases: Phase I: mapping of the faults identified at three mechanical assembly equipment, considering the organization's current habits and methods to identify the types of flaws that affect manufactured parts; Phase II: combination of techniques FMEA and A3 on a model document in A3 format and preparation of a checklist for details of the review; Phase III: the method in the failure analysis in the design phase and also in the solution of conceptual flaws in the mechanical assembly stage and testing, support the registration of the knowledge generated. The analysis of the information was qualitative and quantitatively, including charts and graphs obtained by the data collected. The results showed feasibility of the method proposed for both failure analysis and for the registration of knowledge. Moreover, it was also possible to demonstrate that the adoption of the routine improvement practices, such as the checklist detailing the review, even not comprising all the drawings, can minimize up to 10% the number of parts with failures.
