A PairProgramming session in which one person has significantly more relevant experience than the other. So much so that the less-experienced programmer will be expecting the senior programmer to direct the entire session.
Techniques for dealing with a PairMismatch:
- Don't let it happen (PairProgrammingIsDoneByPeers)
- LetTheJuniorDrive (AntiPattern)
- DialogueWhilePairProgramming
- ChangeDriverRoleFrequentlyAndRegularly
