The purpose of the service request management practice is to support the agreed quality of a service by handling all pre-defined, user-initiated service requests in an effective and user-friendly manner. Service request management is dependent upon well-designed processes and procedures, which are operationalized through tracking and automation tools to maximize the efficiency of the practice. To be handled optimally, service request management should follow these guidelines:

Service requests and their fulfilment should be standardized and automated to the greatest degree possible.

Policies should define which service requests will be fulfilled with limited or even no additional approvals so that fulfilment can be streamlined.

The expectations of users regarding fulfilment times and costs should be clearly set, based on what the organization can realistically deliver.

Opportunities for improvement should be identified and implemented to produce faster fulfilment times and take advantage of automation.

Costs are the amount of money spent on a specific activity or resource. From the service consumer’s perspective, there are two types of cost involved in service relationships:

Costs removed from the consumer by the service (a part of the value proposition).  For example, for a car sharing service, the customer does not pay for the actual cost of purchasing the car.
