Driver/Navigator Switch Techniques

Pair programming encourages participants to switch roles often. These procedures make sure everyone has a chance to drive and navigate. It is crucial that both partners spend an equal amount of time performing each role. There are a few techniques you can use to encourage this.

Chess Clock
