I noticed that a few research centres and university departments provide a multi-year strategic plan document on their websites. For example, IIT (Italian Institute of Technology) and Stanford Computer Science Department.
The plan usually describes the main goals and purpose of the institution, both in science and in research management.
Why do they actually do it?
Is it just a way professors and researchers try to predict their future? Or is it a solid way to show their future scientific directions to the world?
What happens if the strategic plan is not respected by scientists and events during the following years?
And why so many institutes actually don't do it?
