Erlang C still has a place in contact centre workforce planning, but it was built for a simpler world. This article explores where it still works, where it breaks down, and what leading contact centres are using instead.
Resources for Call Centre Managers
You started on the phones. Worked your way up through team leader to manager. You've probably only worked in one or two contact centres, which means you've learned how those operations ran — but you don't know what you don't know about how other centres do things better.
ACXPA exists to fill that gap. We bring you global best-practice frameworks, proven strategies, and specialized tools that help you run a smarter operation — from WFM calculators that make complex staffing simple to navigating AI, improving quality, and connecting with other managers who've faced the same challenges.

Most contact centre managers started on the phones and worked their way up. You learned how your centre operates, you know your team, and you've figured out what works in your environment. But unless you've worked across multiple organisations or industries, you're only seeing one way of running a contact centre — and you don't know what you don't know about how other operations achieve better results with smarter frameworks.
