This article has multiple issues. The two programmers switch roles frequently. Along with code development time, other factors like field support paired t test example problems with solutions pdf and quality assurance also figure in to the return on investment.
Pair programming might theoretically offset these expenses by reducing defects in the programs. In an attempt to share goals and plans, the programmers must overtly negotiate a shared course of action when a conflict arises between them. In doing so, they consider a larger number of ways of solving the problem than a single programmer alone might do. This significantly improves the design quality of the program as it reduces the chances of selecting a poor method. In “promiscuous pairing”, each programmer communicates and works with all the other programmers on the team rather than pairing only with one partner, which causes knowledge of the system to spread throughout the whole team.
Pair programming allows the programmers to examine their partner’s code and provide feedback which is necessary to increase their own ability to develop monitoring mechanisms for their own learning activities. Pair programming allows team members to share problems and solutions quickly making them less likely to have hidden agendas from each other. This helps pair programmers to learn to communicate more easily. This raises the communication bandwidth and frequency within the project, increasing overall information flow within the team. There are both empirical studies and meta-analyses of pair programming. The empirical studies tend to examine the level of productivity and the quality of the code, while meta-analyses may focus on biases introduced by the process of testing and publishing.
