An alternative method for preparing FMECA´s

Some of the practical problems associated with the application of formal, MIL-STD-1629, failure modes and effects analyses (FMEAs) are addressed, and an alternative cost-saving methodology is proposed. The technique is fast in application and allows engineers to influence design decisions, using FMEA studies, as the design progresses. The technique follows the spirit of the standard, rather than its letter, and overcomes what is considered one of the major shortcomings of the standard, since a single failure can effectively only disrupt one system function. It is noted that the methods described have already rapidly gained acceptance and wide application in the United Kingdom
