Each customer contact centre consists of a half-dozen departments representing functional specializations (computer systems, intranet infrastructure, storage systems, enterprise software systems, customer billing, etc.). These centres typically have more than two dozen employees in each department. When a client submits a problem to the centre by email or telephone, the message or call is directed to the department where the issue best applies. The query is given a “ticket” number and is assigned to the next available employee in that department. Individual employees are solely responsible for the tickets assigned to them. The employee investigates and corrects the issue, and the ticket is “closed” when the problem has been resolved. If the client experiences the same problem again, even a few days later, a new ticket is issued and sent to whichever employee is available to receive the ticket. A client's problems are almost always handled by different employees each time, even when the issue is sent to the same department. Furthermore, when a customer centre department is heavily backlogged, clients are redirected to the same department at another regional centre where their problem can be addressed more quickly.…
