  • Build, parameterize, and sanity-check models representing the current manufacturing system.
  • Collect data from the floor and extract data from SAP (time studies, downtime logs, scrap data, material consumption, WIP counts) and load it into the model and KPI dashboards.
  • Run what-if scenarios to quantify effects on throughput, WIP, lead time, utilization, and other KPIs.
  • Help identify bottlenecks and waste by interpreting simulation results, simple statistics, and visualizations, then propose candidate improvement scenarios.
  • Prepare concise reports, slide decks, and visual instructions that translate model results into actionable changes for the engineering & production teams.
  • Document scenarios with KPI comparisons, and a recommendation memo per study (product & process).
