artifact description
This project studied MilliporeSigma’s changeover efficiency within the Opticap® XL encapsulation process to alleviate throughput issues associated with increasing demand. Our team conducted time and observational studies, together with stakeholder interviews, to identify and prioritize improvement areas. We developed a production schedule optimization tool, Single Minute Exchange of Dies analysis for changeover tasks, and conditions to streamline melt-check procedures. We recommend our deliverables be implemented to improve changeover efficiency, and estimate that 230 minutes can be saved in changeover time over two days.
