Workforce Management: What is Average Process Time (APT)?
Updated: Dec 31, 2021
Let's take a look on the Average Process Time in a contact center environment.
So what is Average Process Time (in short - APT)?
Average Process Time is the time taken by a Customer Service Representative (CSR) to complete a task successfully.

Few instances are below
Time taken to complete an order on Client application for sales, promotional campaign, installation, repair and so on
Time taken for payment orders
Time taken to explain a new product, billing, policies and so on
Time taken to provide information, legal action, notification and so on
Average Process Time can vary between different scenario and are an important input to define workload. APT is also known as Average Handle Time (AHT).
Do you remember the workload calculation - Workload X Average Handle Time
Yes, that's right! Workload calculation can also be defined as:
Workload X Average Process Time
As we talk about Average Process Time, let's discuss about the components by each channel type:
Inbound
In general, Inbound has 3 components to AHT/APT:
Talk Time - As the name suggests, it is the time spent talking with customer
Hold Time - This time is categorized as the time spent holding to transfer the call to other department. For instance, Customer Care transfer the call to Technical Support. The hold time will also include the time the customer is kept on hold to fetch relevant information instead of dead air or silence on the call.
Wrap Time - After every call, we need to document the resolution for future reference. The time spent documenting post call is the wrap time
Outbound
The basic definition for outbound is when a contact center calls a customer for sales offer, upgrade or downgrade services, promotional offer, pre-approved offer, welcome call, scheduled installation or maintenance and so on.
While we call a customer, you may either get connected to a customer or the customer may not answer the call. With this in mind, the AHT has 2 parts in Outbound:
Successful AHT - An outbound dial-in is considered successful when CSR is successfully speaks to a customer; Basically customer acknowledges your call.
Non-successful AHT - An outbound dial-in where the customer is not answering or the number is switched off or there is network issue while connecting
The successful AHT further divides into talk time, hold time and wrap time unlike Inbound as we speak to a customer in this case.
Back-office
Usually back office process disintegrate into multiple stages or steps and average process time is accordingly varies. Let's take an example:
Example: Sales Order Entry - This process can have following sub-processes and accordingly average process time differ:
New Sales Order Creation - Creating a new sales order on client application
Sales order update - Updating any change on the sales as asked by customer or clients
Sales order Cancellation - Cancelling the sales order already created on client application
Order validation - validating commercials as per business rules
Order Status - Check the current status of an order
and so on.
Email is also similar to Back Office.
