> Not following instructions is foreseeable misuse... Depends.
I define "misuse" as using the product for some use other than its intended use. Standing on a chair is misuse of the chair. Misuse (my definition) cannot be foreseeable because it depends on what the user needs to do (and has decided that the product will do what he wants to do). Think McGyver, the TV show. McGyver found imaginative "mis"uses of ordinary items to help him get out of various situations. https://en.wikipedia.org/wiki/MacGyver "Not following instructions" is a fault condition: a fault of a behavior that is specified in the instruction. As a fault, it can be included in a fault tree. A fault tree can only be made for a single top event. Misuse (my definition) and "not following instructions" are not likely to have the same top event and so would have separate fault trees. If you define "misuse" as "not following instructions," then one top event and one fault tree.
