Three questions about evidence based management

The last few days, I have had pleasant email exchanges with Dennis Tourish (University of Kent) and Mark Learmonth (University of Nottingham). Dennis will join in the EBM debate later and Mark still defends his arguments against the emerging evidence based management movement. He also sent me a few articles. Since he published his short paper in ORGANIZATION, he has become a little milder. I've invited him to respond on the blog and share his current views with the rest of the readers.

After reading several publications, there are actually three questions which fascinate me about the evidence based management movement. Please share your thoughts in the comments or write your own posting.

1. What is the core idea and purpose of EBM? What would be the benefit for organizations and society as a whole if management would be based more on evidence?
2. What progress has the EBM movement currently been making? Is there evidence of evidence based management getting a foothold in organizations?
3. What is future for EBM in (research and practice)?

Readers who have written articles on evidence based management (published in academic journals or still in the process or otherwise), please share them with me. I'd like to make a repository with interesting articles on evidence based management.
