The driver’s role is to control the mouse and keyboard and type out the code. They should concentrate on solving the current task while keeping the navigator’s plan-of-action in mind.
The navigator’s role is to read the problem and narrate the plan-of-action. The navigator should be checking for typos or other errors as the driver produces code to catch them as soon as they arise and before they cause further errors. They should also be actively thinking of alternative, more efficient ways to solve the problem.
