When an employee leaves the organization

When an employee leaves an organization what he leaves behind is the knowledge that the person has gained during the time he spent in the organization. There should be mechanisms to capture and utilize this knowledge. If this happens then the organization is on its path to become a learning organization. Employees who had spent years in the organization leave behind a lot of very useful knowledge. Intellectual egos hinder re-usability. This needs to be addressed by the senior management, which in my experience is an area of improvement for many organizations.
