1.Determining the effects that any failure will have on other items in the product or process and their functions.
2.Determining those parts of the product or the process whose failure will have critical effects on product or operation (those producing the greatest damage), and which failure modes will generate these damaging effects.
3.Calculating the probabilities of failure in assemblies, sub-assemblies, products, and processes from the individual failure probabilities of their components and the arrangements in which they have been designed. Since components have more than one failure mode, the probability that one will fail at all is the sum of the total probability of the failure modes.
4.Establishing test program requirements to determine failure mode and rate data not available from other sources.
5.Establishing test program requirements to verify empirical reliability predictions.
6.Providing input data for trade-off studies to establish the effectiveness of changes in a proposed product or process or to determine the probable effect of modifications to an existing product or process.
7.Determining how the high-failure-rate components of a product or process can be adapted for higher-reliability components, redundancies, or both.
8.Eliminating or minimizing the adverse effects that assembly failures could generate and indicating safeguards to be incorporated if the product or the process cannot be made fail-safe or brought within acceptable failure limits.
9.Helping uncover oversights, misjudgments, and errors that may have been made.
10.Helping reduce development time and cost of manufacturing processes by eliminating many potential modes prior to operation of the process and by specifying the appropriate tests to prove the designed product.
11.Proving training for new employees.
12.Tracking the progress of a project.
13.Communicating to other professionals who may have similar problems
