Even so, many managers wonder if the time has come for their own business to implement this technology. Understanding the... technical and commercial criteria This decision prevents hasty investments.

Signs that the operation is ready.

The decision to implement AI-based voice agents You must consider three key variables: volume of repetitive calls, human agent occupancy rate e need for support outside of business hours.

When a large portion of calls deal with recurring questions, such as order status or data confirmation, automation tends to generate... immediate gainIn this scenario, the human agent begins to focus on more complex demands.

Before deciding, it's worth mapping things out:

  • Percentage of calls with repetitive themes
  • Times with the highest dropout rate connection
  • Average time that the team spends on transactional tasks
  • Existence of demand outside of business hours
