What are the advantages and disadvantages of pairwise programming?

Answer 1

Assuming you understand what Pair-wise programming is, we can in general say that it is advantageous because the overall logic of the code written, the idea behind using certain constructs in the code, etc. are known to different people rather than a single head. Since, two or more heads is obviously better than one, we see that Pair-wise programming is certainly advantageous. But, the flip-side is say you are stuck in a situation in the code-development and one fine afternoon you get a flash but you cannot code because your partner is not there. Also, increased costs is another disadvantage. These are the basic points and I can assure you that there are several subtleties involved.
