What is the difference between Procurement and Cost Engineers and is it worth to have both in the team setup? This will be very roughly discussed by using an example and providing a guideline when this might make sense for a company. As always there is no simple answer. Some facts might help to make the decision: size of company; size of commodity, complexity of commodity & skill set of procurement engineers. Fact is that both roles (should) have at least 50% overlap in their expertise.
