Implementation of Failure Mode and Effect Analysis

2020-10-27  A good quality control system is important to be implemented to increase productivity and minimize defects in products. One of the quality control methods is failure mode and effect analysis (FMEA). This study uses the FMEA to identify the causes of the defects and recommend the prevention methods to overcome the causes of the defects in an Indonesian paper mill.

Application of Design Failure Modes and Effect

The failure mode for each component has been determined. The effects of failure were then categorised as Local effect, Next effect and End effect. This categorisation helps in identifying the root cause(s) easily and applying severity rating accurately. The relationship between failure mode and root cause may not be always one to one.
