Criterion	Operations Fault Tree Analysis	Product Discovery Outcome-Driven Innovation	Innovation Design Thinking	Operations Failure Mode and Effects Analysis
Purposedifferent	For a critical top event with several possible triggers, the method logically models failure paths. It makes visible which combinations of conditions can lead to damage.	Outcome-Driven Innovation clarifies customer problems, solution opportunities, and evidence. It separates jobs, desired outcomes, importance, satisfaction, and opportunity, and captures results as desired outcome statements, an opportunity landscape, and segments by underserved needs.	For complex user problems with an uncertain cause, the method connects observation, interpretation, and experiment into a learning cycle. It keeps the focus on real needs and avoids premature solution language. This produces robust decisions for product and service.	For a process, product, or service with noticeable failure risks, the method assesses possible failure modes in advance. It directs attention to combinations of occurrence, effect, and detectability.
