Introduction
Welcome to our comprehensive guide on Erlang C staffing call centers, where we will explore the revolutionary method of staffing and managing call centers. In today’s fast-paced world, businesses are under tremendous pressure to offer exceptional customer service while maintaining efficiency and productivity. A call center is one such department that is critical to enhancing customer experience, and therefore, it is essential to have a well-structured staffing strategy in place.
In this article, we will discuss Erlang C staffing, which is a mathematical formula that determines the required number of agents required to handle a specific volume of calls at a particular time. This formula has been proven to be highly effective in optimizing the performance of call centers by minimizing wait times and improving response times. We will also delve into the various benefits of Erlang C staffing and why it is an essential tool for every call center manager.
What is Erlang C Staffing?
Erlang C staffing is a mathematical formula used to calculate the number of agents required to handle a particular volume of calls at a set time based on various factors such as call volume, call duration, service level, and shrinkage. The formula was developed by Agner Erlang, a Danish mathematician who first used it to determine the number of telephone lines required for Copenhagen’s telephone exchange in the early 1900s.
Today, Erlang C staffing is widely used in call centers worldwide because it accurately predicts the number of agents required for different service levels while minimizing costs and maximizing efficiency. This formula has been extensively analyzed and tested, and it has proven to be highly effective in optimizing call center performance.
How Does Erlang C Staffing Work?
At its core, Erlang C staffing works by taking into account the number of calls handled by the call center, the average duration of each call, and the service level the call center aims to achieve. Based on this information, the formula calculates the number of agents required to handle calls while meeting the service level target.
One of the key advantages of Erlang C staffing is that it takes into consideration the shrinkage factor, which is the amount of time lost due to agent unavailability such as breaks, training, and meetings. By including shrinkage in the calculation, the formula ensures that there are enough agents available to handle calls even when some agents are unavailable due to various reasons.
Benefits of Erlang C Staffing
Erlang C staffing provides several benefits to call centers, including:
- Optimized staffing levels: Erlang C staffing calculates the exact number of agents required to handle calls, which helps managers avoid overstaffing or understaffing scenarios.
- Improved customer experience: By accurately predicting the required staffing levels, Erlang C staffing minimizes wait times for customers, improves response times, and enhances overall customer experience.
- Cost savings: Erlang C staffing helps call centers save costs by avoiding overstaffing and minimizing the number of agents required to handle calls while still meeting service level targets.
- Data-driven decision making: Erlang C staffing is based on accurate data and takes into account multiple factors, which helps managers make informed decisions about staffing and resource allocation.
How to Implement Erlang C Staffing in Your Call Center
Implementing Erlang C staffing in your call center involves the following steps:
- Gather data: To use the Erlang C formula, you need to collect data on call volume, call duration, and shrinkage.

- Monitor and adjust: Monitor call volume, service level targets, and other metrics regularly to ensure that staffing levels are optimal.
FAQs
What is the difference between Erlang A and Erlang C?
Erlang A is used to calculate the probability of a call getting a busy signal, while Erlang C is used to calculate the number of agents required to handle calls to meet a service level target.
Can Erlang C staffing be used for non-call center environments?
Yes, Erlang C staffing can be used for any service environment that involves handling customer requests, such as customer support centers or help desks.
How do I calculate shrinkage in Erlang C staffing?
Shrinkage can be calculated by adding up the total amount of time agents are unavailable due to breaks, training, meetings, or other reasons and dividing it by the total available working time.
What is the ideal service level target?
The ideal service level target depends on the call center’s business requirements and customer expectations. However, a commonly used service level target is 80/20, which means that 80% of calls should be answered within 20 seconds.
What is the impact of understaffing on call center performance?
Understaffing can lead to longer wait times for customers, lower service levels, and increased agent burnout and turnover rates.
What is the impact of overstaffing on call center performance?
Overstaffing can lead to higher costs, decreased agent productivity, and lower agent morale due to a lack of work.
Can Erlang C staffing be used for outbound call centers?
Yes, Erlang C staffing can be used for outbound call centers by taking into account factors such as call volume, call duration, and agent availability.
What is the role of technology in Erlang C staffing?
Technology plays a critical role in Erlang C staffing by providing accurate data on call volume, call duration, and other factors required for the formula. It also helps managers monitor call center performance and make informed staffing decisions.
What is the relationship between Erlang C staffing and workforce management?
Erlang C staffing is a critical component of workforce management, which involves managing and optimizing every aspect of the call center’s workforce, including staffing, scheduling, training, and performance management.
What is the impact of agent skill level on Erlang C staffing?
The agent’s skill level is a crucial factor in Erlang C staffing because the formula assumes that all agents have the same skill level. However, if some agents have higher or lower skill levels, the staffing requirements may need to be adjusted accordingly.
What is the relationship between Erlang C staffing and call routing?
Erlang C staffing and call routing are closely related because call routing systems use the staffing requirements calculated by the formula to route calls to the appropriate agent or queue.
What is the impact of seasonality on Erlang C staffing?
Seasonality can have a significant impact on Erlang C staffing because call volume and other factors can vary significantly depending on the time of year. As a result, managers may need to adjust the staffing requirements to accommodate seasonal changes.
What is the impact of call types on Erlang C staffing?
Call types can have a significant impact on Erlang C staffing because different types of calls may require different agent skill sets, call durations, and service level targets. As a result, managers may need to adjust the formula based on the call types handled by the call center.
Erlang C Staffing: Maximizing Efficiency and Productivity
Erlang C Staffing in Action
Now that we have explored the various aspects of Erlang C staffing, let us take a closer look at how it works in real-world scenarios. The following table provides an example of how Erlang C staffing can be used to calculate staffing levels for a call center:
| Service Level | Call Volume | Average Call Duration (in minutes) | Shrinkage | Agents Required |
|---|---|---|---|---|
| 80/20 | 1000 | 5 | 25% | 26 |
| 90/10 | 1000 | 5 | 25% | 31 |
| 95/5 | 1000 | 5 | 25% | 36 |
In this example, we assume that the call center receives 1000 calls per day, each call lasts an average of 5 minutes, and the shrinkage is 25%. Based on these factors and the desired service level, the Erlang C formula calculates the required number of agents to handle calls. As you can see, the number of agents required increases as the service level target becomes more stringent.
Conclusion
Erlang C staffing is a powerful tool for optimizing call center performance by accurately predicting the required staffing levels to meet service level targets. By implementing Erlang C staffing, call center managers can minimize wait times for customers, improve response times, and enhance overall customer experience while saving costs and maximizing efficiency.
