Communication technology is the most commonly cited approach to the geographic distance problem in Global Software Development. Synchronous communication technology such as video conferencing attempts to replicate the rich interaction present in face-to-face meetings, and is seen as the best solution for meetings in which reaching agreement is the objective [3]. However, some interactions are highly technical in nature, involving intricate content such as program source code In such cases, text-based media such as email, discussion forums, and even log entries in source code control systems, are more appropriate as they can accurately transmit the fine details of such content [42]. The choice of which communication medium is most appropriate for a given situation depends on more than the information to be communicated and the temporal distance between parties. Several studies note that language skills, culture, and personality affect individual preferences for communication technology. A person’s cognitive or learning style can influence the choice of communication media; based on their observations of team members in distributed contexts, Aranda and colleagues [2] propose a mechanism for choosing technology based on a model of learning style.

Communication media are commonly classified as synchronous and asynchronous. However, in reality, different media fall on a continuum according to the immediacy and richness of interaction. At the same time, various media have different strengths in communicating certain kinds of information. For example, email, wikis, and to some degree instant messaging, are especially useful for conveying detailed technical information such as program source code [42]. Conversely, rich synchronous communication technology such as video-conferencing is appropriate for highly interactive discussions where body language and intonation can convey the degree of understanding or agreement among participants [20, 22]. Language skill can also influence media choice. Programmers with weaker English mastery prefer asynchronous forms of communication (such as email or instant messaging) over telephone or video conferencing, because they provide more time to compose a response; even relatively interactive technology like chat provides enough delay for this purpose [32, 42]. In addition to communication media, a common set of tools shared by all sites, including a configuration management system that stores design documents and meeting minutes, as well as source code, facilitates collaboration [42].
