Fire or Not to Fire a Know-it-All Technical Bully?

I came across the below article and thought it left me thinking what should be the appropriate way to handle a know-it-All technical bully who does not want to share. In an organization like this, people without the know-how knowledge will be at mercy of the technical wizard.

In my opinion, the following must be done

• The technical bully should document his works (systems, applications, etc)
• Audit the Information Systems (IS)
• Create a knowledge-based systems
• There must have a manager in control

Yeah, but he really knows his stuff... [via]
