Abstract
This paper provides an overview and guideline on the use of Failure Mode and Effect Analysis (FMEA) for ensuring that reliability is designed into typical manufacturing equipment. FMEA is a very important method which should be employed in companies for an engineering design, production process, and new product in preproduction and production sphere in product life cycle. Aim of FMEA is establishing links between causes and effects of defects, as well as searching, solving and drawing the best decisions concerning application of proper action. The example of implementing FMEA shows possibility of monitoring chosen production process according to idea of defects prevention. Usage of this method allows keeping a process production focus, reduction in the product development cycle, providing opportunities for cost reduction.
Keywords: Failure Modes and Effects Analysis, Reliability, Quality management, the product life cycle.
