How to improve Reliability

Reduce failure rate …FMEA(Failure Mode and Effect Analysis).

High stress environment test .. Formative Validity.

Classifying, analyzing failures, and planning corrective actions in response to those failures. .. FRACAS (A failure reporting, analysis and corrective action system).

Why Safety

Safety ?

Pollution

Fault Tree Analysis - Review What ?

• A structured team analysis of the possible underlying causes of a known equipment failure.

When ?• root cause analysis of a failure is needed

Why? - (outcomes)• A better understanding of the root causes of a failure (Step 3: Root cause)

• A better set of action plans to eliminate those root causes (Step 4: Solution)
