Critical Entry Time
(Presented at May 15 Full Workgroup Meeting)
Critical Entry Time
• Critical Entry Time (CET)
– The latest time mail must be made available for
an operation if the mail is to be completed by
its planned Clearance Time (CT) in accordance
with the facility’s Operating Plan.
Critical Entry Time
• Operating Plan
– Outlines mail processes to be performed and
target times to be met, to enable an office to
achieve its service standards.
– Provides management with uniform methods of
operation and documentation of processes and
target times.
– Road map to success.
Critical Entry Time
• Clearance time (CT)
– The latest time committed mail must complete
an operation if it is to meet the CET of the next
required operation or its planned dispatch of
value (DOV)
Critical Entry Time
• Dispatch of Value (DOV)
– This is the final regularly scheduled dispatch to
a destination that will allow the mail to arrive in
time to meet the CET for that facility and meet
the service commitment for the mail.
– DOV to a delivery unit is the final regularly
scheduled dispatch that will arrive in order to
complete distribution in order to meet that day’s
scheduled delivery.
Critical Entry Time
• Establishing CETs
– Working backwards from the DOV of the next
downstream operation whether that is in the
same plant or at the next plant that the mail
piece will be processed.
– The cycle is repetitive from first operation
entered in the plant to the last operation for
dispatch.
Critical Entry Time
• Why change a CET?

Current CET no longer meets service requirement
Redistribution of plant ZIP assignments
Upgrade of plant processing equipment
Change in transportation/network
Standardize Process
