When to use it

• Use it when designing products or processes, to identify and avoid failure-prone designs.
• Use it when investigating why existing systems have failed, to help identify possible causes and remedies.
• Use it when investigating possible solutions, to help select one with an acceptable risk for the known benefit of implementing it.
• Use it when planning actions, in order to identify risks in the plan and hence identify countermeasures.
