Distributed Pair Programming: Empirical Studies and Supporting Environments

Abstract

Previous research [1, 2] has indicated that pair programming is better than individual programming when the pairs are physically colocated. However, important questions arise: How effective is pair programming if the pairs are not physically next to each other? What if the programmers are geographically distributed? An experiment was conducted to compare the different working arrangements of student teams developing object-oriented software. The teams were both colocated and in distributed environments; some teams practiced pair programming while others did not. The results of the experiment indicate that it is feasible to develop software using distributed pair programming, and that the resulting software is comparable to software developed in colocated or virtual teams. Our early experiments have led to the creation of a more comprehensive environment for support of distributed pair programming, using dual screen projectors and hymermedia-enhanced video streams. Our findings will be of significant help to educators dealing with team projects for distance-learning students, as well as organizations that are involved in distributed development of software.
