How do you manage a project? by Anticlue

TechRepublic has an article on the top ten project management skills.

<--- Snipped from TechRepublic --->
1. Define the project
2. Plan the work
3. Manage the workplan
4. Manage issues
5. Manage scope
6. Manage risks
7. Manage communication
8. Manage documentation
9. Manage quality
10. Manage metrics

Looking at the list, I began to wonder how do other places manage a project? Do you have a central office responsible for managing all projects? Or is there a project coordinator? Does IT do most of the project management or do the business users?

How does your organization handle project management? or does it even see the concept as existing?
