A recent survey about Enterprise 2.0 applications – social software like blogs, wikis and social networks that started out in the consumer Web 2.0 space but that were repurposed for enterprise use – found that 44 percent of businesses find the technologies “imperative” or “of significant importance” to their organizations.

The report was conducted by AIIM a non-profit organization that researches enterprise content management and surveyed 400 companies.

Despite the number of organizations that deemed Enterprise 2.0 important and who claimed to see the value in Web 2.0 technologies, almost three-fourths (74 percent) acknowledged to having only a “vague familiarity” with the technology. In fact, 41 percent claimed they had “no clear understanding” of Enterprise 2.0 at all.

The responses reflect the fact that businesses are getting involved in using these applications in an ad hoc manner, says Carl Frappaolo, AIIM’s VP of Market Intelligence. As an example, Frappaolo says that line of business departments will often adopt a blog or a wiki separately from the rest of the organization without much thought to the tools going enterprise-wide and integrating with existing platforms.

Of organization who have implemented Enterprise 2.0 technologies, nearly 45 percent said they have done so in this ad-hoc manner. A mere 26 percent of organizations have taken a strategic approach to implementing Enterprise 2.0 technologies.

The reason for this willy-nilly adoption could be that businesses have had difficulty proving the business case for the technologies. When asked what was the largest barrier to Enterprise 2.0 adoption, about 42 percent cited “a lack of a business case” as the main reason.

While Frappaolo says that traditional ROI methods can be used to measure the usefulness of Enterprise 2.0 tools , he says there does need to be less of an emphasis on dollar amounts due to the nature of the technologies, which is mainly to encourage horizontal collaboration across the enterprise.

“It could be you measure ROI around how quickly you went from the concept of a product to market, and how these functionalities might help speed that,” he noted.

The other issue around adoption could center around who within companies is buying Enterprise 2.0 technologies. Frappaolo says the respondents were a mix of business users purchasing SaaS (software as a service) offerings while others were IT buyers looking to support the technologies in response to users gravitating towards similar products in the consumer space.
