How does pair programming work?
2 likes4,863 views
The document discusses pair programming, which involves two programmers working together at one computer. It outlines the benefits of pair programming such as producing higher quality code, solving problems quicker, and enhancing productivity and knowledge sharing. However, it also notes objections to pair programming like the assumption that programming is solitary work. The document argues that pair programming overcomes these objections and is an effective method.

- 17. Objection 1 17 Characteristics of Pair Programming • Brainstorming – Produce higher quality designs. – Catch design flaws early on, different approaches to the solution. • Problem Isolation – Easier for two to find and resolve a problem. – Both thinking about problem differently. • Focus – Keep each other on track. – Different experience levels Pair Programming 3/24/2011
