If you need a McKinsey interviewer led case to practice with, this is a good case to start with.

Case Study Prompt

Your client is a global mining company with a location in South Africa. This particular location is performing below average financially.

The processing plant is located 160 miles inland and it uses a fleet of large trucks to transport minerals from the plant (which is located near the mineral source) to a port city. The minerals are then loaded onto barges and shipped to clients around the world. The plant needs to operate at maximum capacity to meet customer demand.

The minerals produced are commodities with low margins.

McKinsey has been hired to identify the problem and make recommendations to address it.

What would you do first to approach this problem?
