The purpose is to suggest remedial actions using a DMAIC framework to reduce 'Prime Stock for Sales' (PSFS) in the steel manufacturing process. The specific analysis was conducted for a Plate mill in a steel manufacturing industry in India. It utilizes quality tools like 'Pareto analysis' and 'Fishbone diagram' for organizing data and its subsequent analysis. While the 'Pareto analysis' has identified factor(s) giving the highest impact, the 'Fishbone diagram' has helped to find root causes. Based on the recommendations, if root causes can be discarded from the system, a reduction of the PSFS generation gets delivered. It has been established that Non-Conformance of Order (NCO), Excessive Rolling, and Made to Stock (MTS) are the main factors resulting in over three-fourth of the problem. Several recommendations for corrective actions are also proposed for the reduction of PSFS generation, reinforcing that DMAIC 'Six-sigma' methodology is a practical framework for problem identification, remedial action and implementation. In future, based on a detailed experiment, such root cause analysis can be extended to other parts of the plant and any other steel plant facing a similar challenge
