IV. RESULTS
We first describe two elements of pair programming skill (Togetherness and Expediency) and then characterize three patterns of problematic behavior in pair programming sessions: (Getting Lost in the Weeds, Losing the Partner, and Drowning the Partner). We illustrate each pattern with excerpts from actual sessions.
Section IV-E then gives examples of the alternate (high-skill) case, where pairs manage to avert these problems.
A. Two Elements of Pair Programming Skill
Togetherness. Good pairs manage to stay together, that is, to establish and maintain a shared mental model throughout their session. They detect and address relevant discrepancies in each other’s understanding of their task, work state, software system, and software development in general.
Expediency. Good pairs balance short-term goals, such as identifying a defect or implementing a new feature, and longterm goals, e.g., addressing any member’s knowledge gaps.
