Choose the right perspective

Match the person's scope to your question: regional and site COOs suit questions about running a country or hub, while COOs of operations, technology or business lines suit questions about processes, controls and change programs within a function. Consider how long the person has held the relevant role before relying on them for detail about current practice.
