Studies indicate that 80% of the typical help desk budget is salary. Frequently, Help Desk managers worry about staffing levels more than any other matter. These managers need a methodology to determine said levels. The usual Erlang formulas from queuing theory do not always work because of the wide diversity of Help Desk entry points (phone call, e-mail, fax, etc.). This theory is helpful for some call centers but not for the more complex Help Desk environment. Therefore, staffing appropriately has a major impact on the business and the bottom line.
This model can be staffed with a single person or a few. It is designed to make it easier for the customer to have one phone number to call. In most cases, however, this model creates more problems than it solves; most often the "Gatekeeper" cannot solve the problem, creating a bottleneck instead, resulting in very low customer satisfaction.
This structure sorts the calls into special groups using technology rather than people. Each call is then transferred to someone who can solve the customer's problem, a "specialist." With this model, additional staff is required in order to resolve the issues in each category; and, due to the fact that call volumes are not predictable, a lot of time can be wasted. Often, customers have more than one problem they are calling about which is a big drawback to this design.
In part two, we will discuss the financial impacts of various Help Desk staffing models!
