What is skills-based routing?
Skills-based routing is a way of deciding which agent gets each contact. Instead of sending calls to whoever is free next, the system looks at what the call needs and what each agent can do, then makes a match. A call about a complex billing dispute goes to an agent trained in billing disputes; a call in Samoan goes to an agent who speaks Samoan; a call from a business customer goes to the business team.
It’s a feature of the automatic call distribution (ACD) engine in most modern contact centre platforms, and the same logic is applied to webchat, email and social messages in an omnichannel set-up.
How skills-based routing works
There are two halves to the match: identifying what the contact needs, and knowing what each agent can do.
Identifying the need
The system works out the required skill from information such as:
- the number the customer dialled
- the options chosen in the IVR
- the customer’s account, segment or history in the CRM
- what the customer said, using intent recognition in speech-enabled or AI front ends
- the content of an email or chat message
Profiling agents
Each agent is assigned skills, often with a proficiency level (for example 1 to 5). Routing rules then set the order of preference: try the most proficient agents first, widen to less proficient agents after a set wait, and fall back to a general queue if needed. This “expanding” approach stops callers waiting too long for a perfect match.
Why it matters
Getting the call to the right person first time has a direct effect on results:
- Higher first contact resolution because fewer calls are transferred or escalated.
- Lower average handle time because agents handle work they know well.
- Better customer experience, especially for vulnerable customers who can be routed to specially trained staff.
- Smarter use of specialist staff, who spend their time on the calls that need them.
Common pitfalls
Skills-based routing can backfire if it’s over-engineered. Each extra skill creates a smaller pool of agents, and small pools are inefficient: calls wait for a specialist while other agents sit idle. This is one reason Erlang C calculations favour larger combined queues.
Skills also need to match reality. If agent profiles aren’t updated after training, or the routing rules no longer reflect the call types coming in, calls end up in the wrong place. Workforce management teams need to roster by skill, not just by headcount, so each skill group is covered at the right times.
The best results usually come from a small number of well-defined skills, good on-screen guidance so agents can handle a broad range of calls confidently, and regular review of routing reports to spot misrouted or long-waiting contacts.
