Reliability
SPOF (Single Point of Failure)
Single Point of Failure
Single component or dependency whose failure can stop the whole system because no effective redundancy exists.
Examples
- 01A network study shows the plant's single compressed-air compressor is an SPOF: if it fails, every line stops within 10 minutes.
- 02Reliability engineering checks each critical utility for an SPOF before maintenance strategies are changed, including power, cooling and IT.
- 03To remove the SPOF, a second compressor is installed, and the two units now alternate weekly so both stay in good condition.
