What does longest idle mean? #
The longest idle strategy is one of the most common methods for automatic call distribution (ACD) in call centers. It ensures that an incoming call is always forwarded to the agent who has not handled a call for the longest time. This ensures a fair distribution of calls, which optimizes both waiting times for customers and the workload for agents.
This method helps to ensure that no employee is overloaded while others receive too few calls. At the same time, it ensures an even workload for the team so that the call center works efficiently and service level targets are met.
Why is the idle time of an agent important? #
Idle time describes the time between two calls made by an agent. It is a key indicator of the efficiency of a call center, as it provides information about the distribution of the workload.
An excessively long idle time often means that some agents receive too few calls while others are overloaded. Too short an idle time, on the other hand, can indicate an uneven distribution that leads to stress and exhaustion among employees.
To achieve an optimal balance, modern call center software solutions use real-time tracking that monitors idle time and automatically makes adjustments.
How is the idle time calculated? #
The idle time is calculated by measuring the time that has elapsed since the last completed call from an agent. The following table shows an example of the calculation of the idle time and the subsequent call distribution:
| Agent | Last call ended at | Next call at | Idle time | Receives next call? |
|---|---|---|---|---|
| Agent A | 2:05 pm | 14:10 Uhr | 5 minutes | no |
| Agent B | 2:02 pm | 14:10 Uhr | 8 minutes | yes |
| Agent C | 2:08 pm | 14:10 Uhr | 2 minutes | no |
As Agent B has not received a call for the longest time (8 minutes), the next incoming call is assigned to him. This principle ensures that the calls are distributed evenly across the team.
Advantages of the longest idle strategy #
The use of the longest idle strategy has numerous advantages for call centers:
1. increased efficiency: the even distribution of calls ensures better utilization of available resources and reduces wait times.
2. better employee satisfaction: agents experience a balanced workload, which reduces stress and increases engagement.
3. higher quality of service: calls are answered faster, resulting in a better customer experience.
4. real-time optimization: By continuously measuring and adjusting distribution, call center performance can be managed in real time
5. cost efficiency: Optimized call distribution reduces unproductive time and improves call center profitability.
Comparison: Longest Idle vs. other call distribution strategies #
Depending on the objectives of a call center, it may make sense to compare Longest Idle with other methods. The following table shows the differences between common strategies:
| Distribution strategy | Functionality | Advantages | Disadvantages |
|---|---|---|---|
| Longest Idle | Call goes to the agent with the longest idle time. | Even workload, short waiting times, high efficiency. | Can lead to delays in small teams. |
| Round Robin | Calls are distributed to all agents in turn. | Even distribution, easy to implement. | No prioritization, waiting times may increase |
| Skill-Based Routing | Call is forwarded to the most qualified agent. | Higher customer satisfaction, specialized service. | Can lead to uneven workload |
| Least Idle | Call goes to the agent with the shortest idle time. | Reduces waiting times, ideal for urgent requests. | Can overload individual agents. |
While Longest Idle is one of the most balanced methods, a combination with Skill-Based Routing or Round Robin can be useful to achieve an even better call distribution.
Summary of the Longest Idle #
Longest Idle is a powerful call distribution strategy that helps call centers efficiently manage their workload, minimize wait times and improve customer service. The even distribution of calls ensures better agent utilization and optimizes overall call center performance.
Longest Idle is an ideal solution for call centers that want to increase their efficiency while ensuring a high quality of service.
