Using systems thinking, we can see that the inputs for a TPS are source documents,
the original transaction record. Source documents for a payroll system can include time
sheets, wage rates, and employee benefit reports. Transformation includes common
procedures such as creating, reading, updating, and deleting (commonly referred to as
CRUD) employee records, along with calculating the payroll and summarizing benefits.
The output includes cutting the paychecks and generating payroll reports. Figure 2.11
demonstrates the systems thinking view of a TPS. 6
