Abstract
The design, monitoring, improvement, and control of processes of all types creates a continual flow of problems that must be solved for processes to perform as designed, and effectively and efficiently serve customers. As a result, various types of problems arise, and numerous problem-solving methods have been developed to address these problems. Using the principles of statistical engineering, we develop a framework that maps problem types to problem-solving strategies. The proposed framework introduces a structured decision logic based on several dimensions: the fundamental intent of intervention (fixing, improving, or creating), whether the solution direction is known or must be discovered, the degree of complexity, whether process requirements are fixed or fluid, and the availability of sufficient problem-relevant data. The framework is designed to help practitioners choose the most effective problem-solving methodology for each unique challenge. This work emphasizes that the problem and its characteristics should drive the selection of tools, not the other way around. The framework is illustrated using real problems from the authors' collective experience. This talk is based on a recent publication of the same name in the journal Quality Engineering.
