The Power of Erlang Staffing in Call Centers

Introduction

Hello and welcome to our exclusive guide on erlang staffing in call centers! If you’re in the call center industry, you know how critical it is to manage and schedule agents efficiently. And that’s where erlang comes in – it’s a mathematical formula used to calculate the optimal number of agents needed to handle incoming calls at any given time.

This guide is designed to help you understand everything there is to know about erlang staffing in call centers. Whether you’re new to the concept or simply need a refresher, we’ve got you covered. So, let’s get started!

What is Erlang Staffing?

First things first, let’s define erlang staffing. It’s a mathematical formula named after the Danish mathematician A.K. Erlang, who developed the model back in 1909. Erlang staffing calculates the optimal number of agents required to handle an expected number of calls at any given time. This model is particularly useful for call centers, where staffing levels can have a significant impact on customer satisfaction and productivity.

Why is Erlang Staffing Important?

So why is erlang staffing so important? Well, first and foremost, it helps ensure that your call center operates efficiently. By using erlang staffing, you can determine exactly how many agents you need to handle incoming calls, reducing wait times and keeping customers happy.

But that’s not all – erlang staffing can also help you save money. By accurately predicting staffing needs, you can avoid overstaffing, which can be costly. And by reducing wait times and improving customer satisfaction, you’ll increase the likelihood of repeat customers and positive reviews, ultimately leading to increased revenue and profits.

How Does Erlang Staffing Work?

Now that we’ve covered the basics, let’s dive a little deeper into how erlang staffing actually works. The formula consists of several variables that are used to calculate the optimal number of agents needed at any given time:

Variable Description
A Number of calls expected during a given period (e.g. 1 hour)
S Average length of each call in seconds
T Target time for answering calls in seconds
C Number of agents available

By plugging these variables into the erlang formula, you can determine the optimal number of agents needed to handle incoming calls at any given time. Of course, this is a simplified explanation, and there are many other factors to consider when using erlang staffing in a real-world call center environment.

Benefits of Erlang Staffing

Now that you have a better understanding of how erlang staffing works, let’s discuss some of the benefits it offers:

  • Improved customer satisfaction: By reducing wait times and ensuring that calls are answered quickly, customers are more likely to be satisfied with their experience.
  • Cost savings: By accurately predicting staffing needs, call centers can avoid overstaffing and the associated costs.
  • Increased revenue: Happy customers are likely to become repeat customers, leading to increased revenue and profits.
  • Efficiency: By knowing exactly how many agents are needed, call centers can operate more efficiently and reduce idle time.

Overall, erlang staffing is a powerful tool that can help call centers operate more efficiently and effectively. By using this formula, call center managers can make data-driven decisions that lead to improved customer satisfaction, cost savings, and increased revenue.

FAQs

1. What is the difference between erlang and agent utilization?

Erlang staffing is a method for determining the optimal number of agents needed to handle incoming calls, while agent utilization is a measure of how effectively agents are being used. Both are important metrics for call center managers to monitor and optimize.

2. Can erlang staffing be used for outbound call centers?

Yes, erlang staffing can be used for both inbound and outbound call centers. The formula can be adjusted to account for the number of outbound calls expected during a given period.

3. How accurate is erlang staffing?

Erlang staffing is generally considered to be a highly accurate method for predicting staffing needs in call centers. However, like any forecasting method, it’s not perfect, and there are many factors that can impact its accuracy.

4. Can erlang staffing be used for multi-channel contact centers?

Yes, erlang staffing can be used for multi-channel contact centers that handle calls, emails, chats, and other forms of communication. However, the formula may need to be adjusted to account for different types of interactions.

5. How often should erlang staffing be recalculated?

Erlang staffing should ideally be recalculated on a regular basis to account for changes in call volume, agent availability, and other factors. Depending on the call center’s needs, this may be done daily, weekly, or monthly.

6. What happens if the actual call volume exceeds the predicted call volume?

If the actual call volume exceeds the predicted call volume, there may not be enough agents available to handle all the calls, resulting in longer wait times and potentially unhappy customers. In this case, call center managers may need to adjust staffing levels on the fly to ensure that customers are served as quickly as possible.

7. How can call centers optimize their erlang staffing?

Call centers can optimize their erlang staffing by continually monitoring and adjusting staffing levels based on call volume, agent availability, and other factors. Additionally, call centers can use other tools and techniques, such as workforce management software, to improve efficiency and optimize agent schedules.

8. What is the impact of inaccurate erlang staffing on a call center?

If erlang staffing is inaccurate, call centers may experience longer wait times, decreased agent productivity, and ultimately, decreased customer satisfaction. Inaccurate staffing can also result in overstaffing, which can be costly for call centers.

9. Can erlang staffing be used for small call centers?

Yes, erlang staffing can be used for call centers of any size. In fact, it can be particularly useful for small call centers that may not have the resources to hire additional agents if they experience a sudden influx of calls.

10. How does erlang staffing affect agent morale?

Erlang staffing can have a significant impact on agent morale. If agents are consistently overworked and understaffed, they may become burnt out and dissatisfied with their jobs. However, if erlang staffing is used to ensure that agents are properly utilized and not overworked, agents are more likely to be happy and productive.

11. What other metrics should call centers monitor in addition to erlang staffing?

Call centers should monitor a variety of metrics in addition to erlang staffing, including average handle time, first call resolution, agent absenteeism, and customer satisfaction scores. By monitoring these metrics, call centers can get a better understanding of their overall performance and make data-driven decisions to improve.

12. Can erlang staffing be used for non-call center environments?

While erlang staffing is most commonly used in call centers, it can be applied to other environments where demand for service is variable and predictable. For example, it can be used in healthcare settings to determine the optimal number of nurses needed to handle patient demand.

13. How can call centers learn more about erlang staffing?

There are many resources available for call centers that want to learn more about erlang staffing, including books, articles, and online courses. Additionally, call center software providers may offer erlang staffing functionality as part of their solutions.
