Variable Analysis: A Problem Solving Method to Help You Stop Guessing and Solve the Hardest Problems

Solving hard problems to root cause requires using both effective behaviors and an effective problem solving method. This book develops and teaches a problem solving method, called variable Analysis. Variable Analysis provides the structure that a skilled problem solver can use to deterministically find the root cause of a problem. The root cause is found by identifying one or more out of spec variables that are directly under your control. You then implement a solution to bring the variables within specification. This allows you to solve the problem without ever guessing, listing potential causes, producing ideas, deriving hypotheses, etc.
