Fishbone diagram…………….

Failure analysis works in the following manner:

1. All errors and defects are categorized by origin.

2. The cost to correct each error and defect is recorded.

3. The number of errors and defects in each category is counted and ranked in descending order.

4. The overall cost of errors and defects in each category is computed.

5. Resultant data are analyzed to uncover the categories that result in highest cost to the   organization.

6. Plans are developed to modify the process with the intent of eliminating (or reducing the frequency of) the class of errors and defects that is most costly.

  1. The causes can be traced back to defects and errors from a variety of sources. If you do nothing about controlling them it also comes with future failures built into it.These future failures are the design errors the materials selection errors the fabrication errors the assembly errors and any transportation damage. When installed further causes of future failures arise from incorrect installation incorrect site assembly incorrect mounting practices inadequate environmental protection and deficient foundations supports.Some of these errors along with commissioning errors and operating errors cause failures early in the equipments operating life and explain early-life or infant mortality failures.
