This document discusses the use of wikis in organizations. It lists several ways that organizations use wikis, including for software development, e-learning, project management, knowledge management, communities of practice, ad-hoc collaboration, tech support, marketing, resource management, R&D, and education. It also discusses factors for success, noting that a 2006 study found key benefits were increased visibility, facilitating work, and supporting business process improvement. These benefits are more likely if wikis are used for new problems rather than routine tasks, the information comes from reliable sources, and combining existing information is seen as equally important as adding new information.
