An article that talks about wikis as disruptive technology within organizations:

What is clear is organizations continue to spend millions of dollars on content management infrastructure solutions, rather than putting more power in the hands of their users to collaborate effectively together. The wiki paradigm is disruptive because it is a low-cost alternative that brings key editing features into the hands of users. The approach increases the collaborative productivity of an organization or its extended ecosystems.

Overall, wikis increase the socialization process, enabling collaboration to generate at warp speed. Socialization underpins the sharing of ideas, and hence innovation capacity increases from wiki infrastructure.

To date, wikis have largely been a grassroots phenomenon. Few senior executives have used a wiki or are embracing collaboration patterns at the speed required for competitive advantage. Compared with new firms embracing the architecture of participation, that puts them at a disadvantage.

A recent IBM international survey of 765 CEOS confirmed that CEOs will say they are for collaboration and for radically shaking up their business models to increase their innovation speed. However, when asked how their organizations are collaborating in different markets, the results in their ability to collaborate effectively were: in emerging markets, 73 percent; in global markets, 51 percent; and in mature markets, only 47 percent.
