If you can google it, do. If a test or a book will provide the answer, run it or read it.
Unfortunately, when it comes to understanding a situation or the root causes of an issue or who has a stake in what you consider doing, Google isn't very useful.
Google doesn't know the situation as it applies to you, nor do outside consultants unless you tell them first. Your people do. But in meetings, politics and a host of social barriers get in the way of sharing situational knowledge fully and honestly. This matters because you rarely get to the right solution without understanding the issue or opportunity.
Which is why XLeap session usually offer anonymity. Anonymity cuts through politics and self-conciousness. People share what they know. Make sense by building on each other's insights, even if they are from the 'wrong' person or department. This gives you a much sharper take of the situation faster than possible by conventional means.
