Lean six sigma: DMAIC -the germane phase define, a practical study.

Abstract

Companies no longer compete with each other only on the final price of their product and or service. Technology allows the search for continuous improvement in processes in all organizations. So a focus for this condition is the practice of lean methodologies, six sigma, and the whole set of tools and techniques. In this sense, this article seeks to investigate how lean six sigma and especially the DMAIC methodology, especially the Define phase, contribute to six sigma practice. It is a practical case study of a lighting company, its assembly line, and its non-conforming finished products. In this way, data collection took place, and the sub-steps of the Define step were developed. The correct execution of each substep contributes positively so that the other stages of the DMAIC can be correctly structured, thus providing subsidies for six sigma and lean to be developed and prosperous in organizations.
