A method of assisting failure mode and effects analysis of a system having a plurality of components includes obtaining data associated with a component, or a group of components, of the system. The component or the group is associated with component type data or group type data, respectively, that includes data relating to at least one failure feature common to all components or groups, respectively, of that type. The component/group data and the component/group type data can then be stored and/or transferred for use in a failure mode and effects analysis of the system.
