Eicher Motors Electrical Engineer Interview Questions and Answers

CFMEA stands for Control Failure Mode and Effects Analysis.

• CFMEA is a systematic approach used to identify and mitigate potential failures in a process or system.

• It involves analyzing failure modes, their causes, and the potential effects on the process or system.

• CFMEA helps in prioritizing and implementing control measures to prevent or minimize failures.

• It is commonly used in industries such as manufacturing, automot...read more

System level DFMEA is given main preference.

• System level DFMEA considers the entire system and its interactions.

• Component level DFMEA focuses on individual components.

• System level DFMEA is more comprehensive and effective in identifying potential failures.

• Example: In automotive industry, system level DFMEA would consider the entire vehicle and its subsystems.

• Example: In medical devices, system level DFMEA would conside...read more
