Project aims to reduce radial side wall rejections in bias cutting. [Step I] identifies the current high level of side wall rejections as the problem area and validates the need for improvement. [Step II] analyzes current processes through data collection and identifies the specific problem as reducing defects in SKU X from Y% to Z% by date. [Step III] uses a fishbone diagram and validation to identify root causes such as machine issues and lack of training. [Step IV] develops a countermeasure matrix to prioritize solutions and an action plan to address root causes. [Step V] checks results through before/after data showing benefits. [Step VI] standardizes improvements through updated documents. [Step VII]
