Purpose – The complexity of problem solving requires use of quality tools to assist in the organization and analysis of information and data surrounding the concern. A proposed classification scheme for problem‐solving tools allows the user to identify the correct tool at the proper time in the problem‐solving process. This may assist the problem solver to efficiently and effectively work toward problem solution. The classification scheme, in the form of a matrix, identifies, organizes, and defines tools of the six sigma problem‐solving process as taught and implemented at a large manufacturing company.Design/methodology/approach – Development of a problem‐solving matrix to enable more efficient and effective use of tools applied to a six sigma project in a large manufacturing company.Findings – The application of the methodology to a case study in a large manufacturing company related to an Air Conditioning (A/C) No Fill concern. The exercise of applying the six sigma tools matrix to this project would h...
