Abstract: This paper presents a critical review of Failure Modes and Effect Analysis (FMEA). Although the method is almost 70 years old, in literature there are still many researchers, both from academy and industry, devoted to improve it and overcoming unsolved and still open problems. The aim of this work consists in analysing a representative pool of scientific papers (220) and patents (109), in order to have an overview of the evolution of the method and try to understand if the efforts spent to improve it effectively answer to the several criticisms found in literature. All documents have been classified according to authors, source, and four technical classes dealing with the applicability of the method, representation of the cause and effect chain, risk analysis and integration with the problem-solving phase. A detailed analysis of the results allowed us to identify the most current problems, the improvement paths, and which other methods and tool are proposed to be integrated with FMEA.
