Control period and offset
Control period
The control period specifies the time span to be considered for the current surveys, control tests, sign-offs, and audits, that is, it is the period in which the activities to be checked took place. The length of control period specifies the time unit, for example, month, quarter, year.
Example for control tests:
If a control is to be tested, the control test specifies the time period of which the control executions must be checked (= control period). Besides the control period, there is a time period to execute the control test (= testing period). The periods relate to one another.
Offset
The offset indicates how many days before the start of the next task execution the control period ends.
Examples for control tests:
The offset indicates how many days before the start of the testing period the control period ends. If you specified one day for the offset, the control period ends one day before the testing period starts. If you specified seven days for the offset, the control period ends seven days before the testing period starts.
(See examples below.)
Calculation
The control period is calculated in relation to the start date of the testing period, for example. (This explanation also applies to the survey period and sign-off period.) The control period is automatically calculated to end as many days before the start of the testing period as specified for the offset.
Testing period of the control test: January 20 to January 22 (= 3 days)
Length of control period: 1 week
Offset to start date: 1 day
The time span of the control period is one week, and it ends one day before the start date of the testing period (= offset). Hence, the control period would be from January 13 to January 19.
Testing period of the control test: January 20 to January 22 (= 3 days)
Length of control period: 1 week
Offset to start date: 7 days
The time span of the control period is one week, and it ends seven days before the start date of the testing period (= offset). Hence, the control period would be from January 7 to January 13.
