How Playvox Helped Zendesk Cut Daily Variance in Half

Zendesk is a global CRM company that builds flexible, scalable software designed to improve customer relationships. Zendesk powers billions of conversations for more than 100,000 brands with hundreds of millions of customers and employs over 4,000 people worldwide. They were stuck making educated guesses around staffing needs and creating schedules by hand, and they had no way to access the information they needed to make adjustments.


  • Forecasting their contact center staffing needs.
  • Visibility into agent performance.
  • Defining and reporting on the success of customer teams.


  • Playvox’s cloud-based Workforce Management solution with intraday forecasting and detailed volume predictions.


  • Variance is consistently under 5% daily.
  • Easier forecasting and workforce scheduling on a global scale.


Erin Filsinger is Director of Workforce Management at Zendesk, and Lyn Miller-Bright is Zendesk’s Senior Manager of Workforce Management. They are in charge of forecasting, planning, and monitoring key performance indicators to help their team deliver an excellent customer experience.

Erin and Lyn are in charge of optimizing staffing and scheduling for Zendesk’s contact center. To do this, they need to be able to accurately predict the volume of incoming customer contacts and make fast changes throughout the day.

But Erin and Lyn didn’t have a workforce management tool that could help them see trends and forecast volumes. They were stuck making educated guesses and creating schedules by hand, and they had no way to access the information they needed to make adjustments.

“Everything we did was manual. It would take a week to create a forecast that we could not adjust.” – Erin Filsinger


Playvox gives Zendesk’s workforce management leadership fast, accurate forecasts that make optimizing their staffing simple.

When Erin and Lyn switched to Playvox Workforce Management, they were excited by how easy it was to implement the workforce management tool and start forecasting.

Within a week, they used the data Playvox Workforce Management collected to accurately pinpoint their pain points. Within 30 days, they coordinated staffing on a 24-hour basis for their entire staff worldwide.

“The Playvox team were with us throughout the whole [implementation] process. They met with us, they made sure our data was right, they were responsive. Their support is what made us successful.” – Erin Filsinger

Playvox has helped with their COVID-19 response, too. When they sent their employees to work from home at the start of the pandemic, having Playvox Workforce Management in place allowed them to make an immediate overnight transition without having any issues with their coverage or scheduling.


Thanks to Playvox Workforce Management, forecasting and workforce scheduling on a global scale are easier than ever. Erin says that using Playvox Workforce Management to analyze the trends in their volume has improved their daily variance significantly: they’ve gone from over 10% variance to being consistently under 5% daily.

Most importantly, Erin and Lyn can see when spikes in customer contacts are happening on an hourly basis and adjust accordingly. Thanks to Playvox, they can deliver the best possible customer experience every day.

“We were able to initiate a global shift alignment within 30 days to know exactly where we needed to put all of our people on what shifts 24/7 because we could see our trouble spots that we were blind to before.”

– Erin Filsinger, Director of Workforce Management

“Life without Playvox would be chaos. Everybody would have to scramble to figure out where they need to be and when. We would have no way of knowing whether or not we are meeting our customers’ expectations.”

– Lyn Miller-Bright, Senior Manager of Workforce Management
