Jerry Bowles has a good article on the Top 10 Management Fears About Enterprise Web 2.0:

Technological Barriers

1. How can I be certain that the information that is gathered and shared behind the firewall stays behind the firewall?
2. How do I control who has access to particular levels of information and databases?
3. How do I protect the integrity of the information from malicious tampering by disgruntled employees or managers?
4. How can I be sure that information is being “tagged” properly for efficient retrieval later?
5. What kind of training do employees need before they can effectively use the technology?

Cultural Barriers

6. How can I monitor the system to make certain that what individuals are saying and sharing reflects company policy?
7. What are the legal dangers in saving and sharing so much loosely supervised input?
8. How do I distinguish “productive” use of the technology from horsing around?
9. How do I “manage” the gathering and disseminating of so much unstructured information?
10. How do I know if I’m getting my money’s worth out of the investment in technology?

This IDC study explores the issues raised by the open source software phenomenon and comes to some surprisingly different conclusions. We first look at the evidence of the growing role of open source among global software developers and find that the phenomenon has spread way beyond Linux, the poster child of the open source movement, and is gaining momentum. We then provide the first estimate of the economic impact of open source on the industry — how much is open source “taxing” the industry anyway?

According to Dr. Anthony Picardi, senior vice president, Global Software, who analyzed IDC surveys from over 5,000 developers from 116 countries, “The use of open source beyond Linux is pervasive, used by almost three-quarters of organizations and spanning hundreds of thousands of projects. Although open source will significantly reduce the industry opportunity over the next 10 years, the real impact of open source is to sustain innovations in mature software markets, thus extending the useful life of software assets and saving customers money. Three distinct business models are identified that differ by their revenue potential, architectural control, and socioeconomic motivations. Our advice to open source vendors is to choose the business model that matches your most important business priority.”
