Teleopti Receives Patent for Chat Staffing Algorithm


Chat staffing algorithm continues thought leadership and innovation on best practices for omnichannel customer service planning

Teleopti, an industry leader for cutting-edge, user-friendly workforce management (WFM) solutions, is excited to receive the patent for a chat staffing algorithm.

Having been the first in the industry to provide a WFM solution for multi-skill, multi-channel forecasting and scheduling, Teleopti’s advanced chat resourcing calculations support contact centers in embracing digitalization with far greater certainty while efficiently meeting customers on the platforms they wish to communicate.

Chat is an ever-increasing part of companies’ customer service offerings so powerful, flexible staffing calculators are needed to accurately schedule which agents need to be working to optimally answer incoming chat conversations. Contact centers today must often schedule interactions via instant chat, but such staffing numbers are derived more from guess work and experience than fine-tuned calculations. This algorithm offers the ability to accurately staff chat channels and scale infinitely, becoming a power player for accuracy and efficiency as the contact center expands or its chat services scale up in size.

Teleopti’s chat algorithm expands on Erlang’s original calculations but brings in the dimension of parallelism. Parallelism comes as, unlike most other scheduled tasks e.g. phone or email, an agent can be working on multiple customer chats simultaneously. The new patented algorithm creates resourcing calculations and sets optimal parameters for number of chats an agent can handle simultaneously, given the external requirements on the chat, such as the contact center’s own KPIs for quality of service or employee satisfaction needs.

Research on chat staffing calculations has been a two-year mathematics doctorate project within the Optimization and Systems Theory division at KTH Royal Institute of Technology’s Mathematics department, in Stockholm, Sweden. The research has been conducted by Teleopti’s Research Engineer and PhD student, Göran Svensson.

Svensson said, “There have been previous works on the phenomena of parallelism but normally in the context of the processor sharing data services. The big difference between this and Teleopti’s new patented algorithm is that a service job in the processor sharing framework is of a known size as soon as it enters the queue whereas a customer’s service need is still of an unpredictable size. Generalizing the Erlang-A model to incorporate concurrency was the first step, this meant increasing the state-space of the problem. Analyzing and solving this problem in steady state was the second step.”

“At Teleopti we hold the mentality that ‘We innovate from the ground up,’ investing in all areas of the WFM innovation process from vital research on algorithms and methodologies through to cutting-edge front-end development for better user experiences,” said Johan Ryding, Head of R&D at Teleopti. “We have an ongoing collaboration with KTH to explore contact center mathematics. Blending detailed research with the development of boundary-pushing functionality means Teleopti builds a WFM solution that is future proof, leading the WFM space.
