ROLE OF CULTURE
“Culture” that characterizes any group is made of the knowledge, beliefs, customs, and practices shared within the group. These are taken for granted, but they guide attitudes and behaviours, which in turn determine actual outcomes. When a business seeks to improve its performance, it must examine its culture and assess the impact of its practices on the desired results.

• Non repetitive outages of long duration
• Tripping of major auxiliaries leading to unit tripping
• Potential areas of multiple unit trips

Reliability
• “Availability is the probability of a device or system being in the operating or up state at a given period t in the future”.
• A = ( Running Time + Idle Time) / (Total Time in the period ) * 100
• “Reliability is the probability of a device or system performing the purpose adequately for the period of time intended under the operating conditions encountered”.
• R = ( Running Time) / (Running Time + Force outage time) * 100
