From the R/W/W post, the five key points in BAH’s success were:

• Empower Evangelists - “when many people think of an evangelist, they think of an individual or two that take up the mantle of enterprise 2.0 on an ad-hoc basis. But Booz Allen went about it in a much more directed way by bringing together a cross-functional team to develop and deploy the software.”
• Draw on Past Experience – “The fact that they drew on past attempts to understand just how they should move forward was a essential factor in the outcome…”
• Know Thyself - “…the real trick is having enough self-awareness as an organization to know when to discard the given wisdom.”
• Create a One-Stop-Shop – “…constructing more silos out of multiple enterprise 2.0 platforms creates more problems than you ever had with just email and filesharing.”
• Just Solve Problems for People – “…an unwavering focus on solving real problems for people within the firm, not aiming at the vague goal of boosting collaboration and openness.”

If you notice, none of these key success factors are really about technology, but instead they are all focused on organizationa behavior and business objectives.
