Native Salesforce assignment does not factor in skills, capacity, and territory together as one decision. First available agent routing sounds simple until you try to make it work at volume. Native round-robin gives the next case to whoever is up in the rotation, regardless of whether they are online, at capacity, or have the skills. Agents who stepped away get cases assigned to them; the cases sit until the agent returns.
The result is queues that look balanced on paper but actually concentrate work on agents who are present and have capacity to absorb it. Customers wait while their case sits on an agent who never picks it up. SLA reporting shows the cost after the fact.
First available is not the same as next in rotation.
Ortoo Orchestrator combines availability, capacity, and skills in one routing decision. Cases route to agents who are actually online with capacity to take the work, not just to whoever is next in line.
