Six sigma project power distribution reliability.

Define: Large chemical site had significant losses due to power outages.
Measure: Dollar value determined for each failure and the total. Each failure was assigned to a major component.
Analyze: Mapped the entire system by major component and identified failure rates for each major component. Found areas with projects scheduled that were very unlikely to fail and would add nothing to overall reliability. Other components were being ignored and had a highly likelihood of causing an outage.
Improve: Developed plan for each component depending upon failure mode and frequency for that component. Made a 10X reduction in the dollar losses due to power failures on site.
Control: Track each major component and modify action plan based on failure mode if needed. System shared with other locations.
