Why do problems repeat? Because we haven't eliminated their causes!
And to understand those causes, we need more than the 5-why analysis; we need logic-trees! The following video introduces the theory and provides practical examples. It gives you a “jump start” into the world of expert problem solving.
Causal Factor Tree Analysis
Use the Reality Tree or Causal Factor Tree to analyze event-based problems, such as disasters, accidents, and major breakdowns. The Causal Factor Tree Analysis (CFTA) is based on sequential flow, connecting causes with AND logic.
Fault Tree Analysis
Use the Fault Tree to analyze risks and rule-based, reoccuring problems, such as defects, delays, complaints. The Fault Tree Analysis (FTA) is based on sequential and parallel flows, connecting causes with AND and OR logic.
The 8 Human Failures
Use the concept of the 8 Human Failures to analyze errors from action slips and memory lapses, rule-based and knowledge-based mistakes, and also the different types of violations, the reasons for breaking rules and promises.
Problem-Solving Courses: Learn the Theory, Apply Your Knowledge, Earn Your Certificate
To get started with formal problem solving, take the White Belt course (2 days) or Basic Problem Solver course (3-5 days). For anyone already experienced in systematic problem-solving, take the advanced course (5-10 days) or expert course (10-20 days) to successfully tackle critical and complex problems.
