How would you go about identifying which of our business units has the most potential for cost reduction? What data would you look at?

Why This Is Asked
AGI seeks analysts who can drive efficiency across its portfolio, from Megaworld's construction costs to Golden Arches' operational expenses. This tests analytical thinking and cost management acumen. (Note: As no actual interview questions are documented, this is based on the conglomerate's need for cross-subsidiary performance improvement.)
General Approach
Structure your answer around a framework: data collection, cost categorization, benchmarking, and feasibility assessment. Mention specific analyses like variance or Pareto, and end with a recommendation based on data.
Sample STAR Answer▾
Situation
In my role as an analyst at a manufacturing company with multiple product lines, the management wanted to reduce overall operational costs by 10%. I was asked to analyze each product line's cost structure to find the biggest savings opportunities.
Task
I needed to identify which product line could yield the highest cost reduction with minimal impact on quality or revenue.
Action
I gathered cost data from each department, breaking down expenses into fixed and variable costs. I benchmarked our unit costs against industry averages and conducted a Pareto analysis to pinpoint the largest cost drivers. I then interviewed process owners to assess the feasibility of reducing those costs, such as by renegotiating supplier contracts or reducing waste.
Result
My analysis recommended focusing on one product line where raw material costs were 20% above industry average. After renegotiation, we saved 5% of total company costs, meeting half of the target in the first year.
