Failure Mode and Effects Analysis helps you understand what works: for your problem, name all the things that are contributing to the failure, ask how often it occurs, list the actions you’ve taken to ensure it does not recur, then analyse which solutions worked.
One of the simplest causal analysis methods involves asking yourself “why” five times. You start by identifying the problem. “My house is always disorganised.” Then, you ask yourself why that is the case. You create a chain of inquiry that offers insight about the core of the problem.
