In order to facilitate the development or maintenance of an effective OHS Management System, the OHS professional should be competent in the use of quality management processes and their application. A quality management process is a highly intentional system designed to provide consistent results, improve efficiency, and continuous improvement. An effective quality management process requires a strong understanding of an organization’s inter-related processes and goals. In manufacturing, the OHS professional may need to demonstrate an understanding of the Lean methodology. Lean is a methodology to reduce waste in a manufacturing system without sacrificing productivity and is a common language that will streamline communication between OHS professionals and business managers and executives.
