Use the following guidelines to determine whether the reported data is acceptable. These guidelines represent the minimum that you must do to verify that the recorded measurement values are consistent with the expected and historic values. Perform additional checks as necessary.
To check the acceptability of hourly attendant measurements reports, verify that:
The system clock or group size was not changed during the measurement hour. If the system clock was changed, the minutes field displays double asterisks (*). For example, 11**. All other fields for the indicated time interval display zero.
The average work time (AWT) typically ranges from 10 to 30 seconds per call. Specific applications might accept different values.
The sum of Time Talk (in CCS) and Time Avail (in CCS) must not exceed 36 multiplied by the group size. For example, with two attendant positions, the sum should not exceed 2 X 36 = 72 CCS for data collection.
The attendant can have up to six calls on hold at one time.
