An installation that has a limited variety of computer applications
might have the following billing objectives:
- The charges must accurately represent the amount of time required
for each application.
- The charges must be consistent for the same types of applications.
(For example, all payroll applications must have the same base cost.)
To fulfill these objectives, the installation might take the following
steps to create its billing algorithms:
- Using SMF, establish an average-run time (through actual running
or simulation) for each type of computer application.
- Estimate the average-run-time cost for each type of application.
- Set a cost-per-hour rate (using steps 1 and 2).
- Multiply this rate times the “job elapsed time” recorded
by SMF for each application.
