What Causes Unexpected High Call Volume?

There are numerous reasons behind the unexpectedly high call volume. Sometimes, the overflow of customers reaching the call center can be the reason. In rare cases, the external environment could also be the reason.

For example, the global pandemic can cause panic, eventually increasing the number of incoming calls to the call center and creating an outage or technical glitch.

Some of the other causes include:

  • Peak periods: Certain times of the year, such as holidays and sales seasons, can result in increased call volumes.
  • Successful marketing campaigns: If the marketing campaign is successful, it can directly increase call volume.
  • External Events: External events like launching a product or service can cause spikes in calls. It’s because customers become eager for features, benefits, pricing, and availability of the new products.
  • Technical Issues: Some system failures, such as a website crash, software glitch, or network connectivity problem, can cause many customers to contact the support system. This results in sudden call volume spikes.

Challenges Posed By Unexpected Spikes in Call Volume?

Unexpected spikes in call volume can have numerous impacts, such as operational inefficiencies, company reputation, and customer experiences.  

Some challenges are listed below:

1. Staffing challenges

In some high seasons, the unpredictable increase in call volume always creates an imbalance between the inbound call volume received and available agents. When there isn’t enough staffing to handle calls, this leads to longer waiting times, which can cause customer frustration.

2. Productivity concerns

Unexpected increments in call volume can stress call center agents, eventually resulting in low motivation, spirit, and burnout. These effects can negatively impact the company’s efficiency and productivity, compromising customer experience quality.

3. Operational inefficiencies

Some sudden changes in call volume can disrupt the call center’s system of work. This can cause problems with call routing, make longer calls, and result in agent dissatisfaction. Despite frustrating customers, this will negatively affect the company’s efficiency. 

4. Brand Reputation

When lots of calls come in unexpectedly, there might not be enough agents to answer them all quickly. As a result, customers have to wait a long time for their calls to be answered, which makes them unhappy. If customers have bad experiences, they might say negative things about the company, which can make other people think poorly of it, too. This negatively affects brand reputation.
