Cost Simulation and Scenario Analysis - Perform product cost simulations for BOM changes, HPU changes, yield improvement, and other approved scenarios. - Compare alternatives and quantify the cost impact by product and product line to support management decisions. 5. Actual Cost, Variance, and Savings Analysis - Analyze variance between actual product cost and the approved cost model or roadmap. - Identify the main cost drivers and clearly explain whether the variance is caused by assumptions, timing, data, or execution gaps. - Track cost-improvement initiatives and cost-saving realization; validate that reported savings are supported by actual results. 6. FTA and Management Support - Prepare model, form and supporting analysis for Free Trade Agreement (FTA) applications. - Provide management-ready summaries, recommendations, and ad hoc financial analysis as required. - Manage priorities and deadlines across multiple product lines while maintaining accuracy and documentation quality.
