Case 1: The Inconsistent On-Time Delivery (OTD)

  • Question: How would you analyze this dataset to diagnose the problem?

What initial insights might you present to your manager?
  • What We're Assessing: Data literacy, analytical rigor, ability to work with a messy real-world dataset, and skill in identifying patterns rather than just looking at top-line numbers.

Case 2: The Rising Warehousing Costs
