Every business executive knows that customer satisfaction is always generated into the overall income of the company and that the qualitative service is an essential element for achieving high profits. Resolving a problem on the first contact with a call center service is the main objective of remote support due to the fact that each additional action after it whether incoming or outgoing calls, visits, applications and so on require labor otherwise avoidable.

How to Improve Call Center Customer Service?

Service Level is one of the most common indicators showing the productivity of a call center and its level of correspondence to the target figures established in a company. In other words, this index characterizes the percentage from the total call center occupancy an employee has been able to take over in a time period set by their manager.

Service Level usually takes about 20 seconds but can be occasionally altered by the management of an enterprise depending on the type of products it manufactures.

How is Call Center Service Level Calculated?

The servicing level indicator consists of two key elements:

  • Percentage — characterized by the rate at which an application is accepted.
  • Call center service levels standards — manually set by the executives of a company.

These two indexes ratio is what Service Level eventually boils down to. When 80% of the requests are accepted within the 20 seconds time range — the result is documented as the 80/20 ratio. Let’s look at each part of the puzzle with more details.

What is Service Level in Call Center in Percentages

This component can be represented in two different formulas:

  1. Generalized simple calculation

(Number of calls received over the set time interval / Overall number of incoming calls on the line) * 100%.

The drawback of this call center service level formula is that it disregards the number of lost calls. Many experts in this industry consider a call to be wasted if the duration of an unserved call has reached over 5 seconds (up until this threshold there is a high possibility of a wrong phone number input on the side of a customer).

    2. The next ratio takes such calls into consideration

(The number of calls received in the set time interval / (Overall number of incoming calls on the line - Over 5 seconds-long calls)) * 100%.

Benchmarks Established by the Management

Customer service levels widely accepted in a company is a conditional figure determined mostly by the kind of manufactured products and specifics of the market environment. In an eventful niche of the business, long periods of time clients spend on waiting on the line can be hazardous for the financial wellbeing of the company, while the clients are not going to deem the delay too much of inconvenience if their problems were eventually resolved by the technical support of other faculties.

Call Center Workers

From a customer’s point of view, the perfect deal would be an instantaneous call acceptance where the Service Level would draft the 100/0 ratio. However, most companies are not going to implement such conditions for their clients because of the immanent personnel expenses increase. At the same time, in peak periods when the line is overflown by incoming calls, the company may suffer big customer churns and generally damage its reputation. Finding the optimal ratio is the main task for large business executioners substantial majority of which are showing a profound understanding of expectations of their clients.

Most enterprises stick to the 80/20 rule, though the threshold may be risen up to 90% in 10 to 20 seconds in case of more high competitive business realms. The entrepreneurs of not so ambitious nature struggling in less competitive and saturated fields can adhere to something like a 70/30 ratio.

Call Center Occupancy Formula

Occupancy Level is the amount of time an operator spends receiving the incoming calls and applications. For instance, if a consultant spends 54 minutes of each hour communicating a client, this sums up their occupancy level to 90% (54 / 60). However, this doesn't conclude that the operator was slacking off for the rest of the hour. They could have spent the rest of the time on other tasks connected to the production process such as sending emails to the managers, technical support assistants, meetings, gatherings and so on.

Call Center Occupancy

Bearing in mind all these functions we can represent the occupancy definition call center as:

(Time spent working with a client / (The period of time an assistant is available - Time spent on auxiliary working activities)) * 100%.

This formula isn't, in fact, universal and is subject to change depending on the peculiarities of a business it is implemented in (level of competition, season, etc.), as well as metrics established in a company (time spent talking on the line, logging in and logging off the system, etc.)

The percentage is suggested to be kept in the bounds of 85-90%. Exceeding this threshold might lead to the overpressure on employees, their subsequent motivational burnout, decrease in the level of consulting quality and incapacity of performing auxiliary functions. The numbers below the threshold may indicate the number of personnel not optimal for achieving the highest efficiency within the given conditions, inadequate marketing or advertising strategy and poor management control.
