Guideline for Developing and Implementing a Charging System for Data Processing Services. Category: ADP Operations. Subcategory: Computer Performance Management

摘要

These guidelines describe a step-by-step methodology for developing and implementing a charging system for use in Data Processing (DP) facilities. Charging for DP services refers to distributing the costs of providing DP services to the users who receive the services. The distribution of costs requires definition of the basic DP services, the resources used to provide the services, and the costs incurred to obtain and make use of the resources. A charging system is comprised of two subsystems: the rate-setting subsystem and the billing subsystem. The rate-setting subsystem incorporates procedures for forecasting the use of each service, forecasting the costs of the resources used to provide each service, and establishing the rate to be charged for each unit of service. The billing subsystem includes procedures for monitoring the use of services, applying the billing rates to compute the total charge for the services each user receives, and reporting the charges to the user and to appropriate accounting groups.
