Today, I had a meeting with my supervisor, Jill Lim, the Infineon Finance Controlling Operation Manager. She provided a detailed explanation of our department's responsibilities. Our department focuses on controlling the company's operational costs. Each year, we are tasked with forecasting the next year's Target Cost Rooming (TCR) and ensuring that our forecast aligns with the CFO's target. At the end of each month, our team calculates the actual cost price and compares it with the TCR. If the actual cost price exceeds the TCR, we are responsible for identifying the root cause within the relevant operational department and implementing measures to control their costs.
