Put tasks in a shared queue and let qualified agents claim work rather than pre-assigning. Keeps the busiest person busy, the best person on the hardest case, and nothing in the wrong inbox.

Use pull-claim work queues when:
Support queues are the canonical example. So are credit review teams, content moderation panels, and sales deal desks.
Tasks land in a shared queue, typically ordered by priority or SLA deadline. Agents pull the next available task they're qualified for. While held, the task is invisible to others. If the agent can't finish it, they release it and it returns to the queue.
Contrast with push-assignment: the system picks an agent and sends the task to them. Push is simpler but brittle — assigned person goes offline, task stalls.
Self-selection bias is real. Agents will cherry-pick easy tasks and leave hard ones rotting. Combine pull-claim with aging (hard tasks get higher priority over time) or load balancing (if your queue grows, enforce round-robin).
Not every agent can work every task. Tag tasks with required skills (language:es, tier:vip, amount:>10k) and let agents see only the subset they're qualified for.
Two agents claiming the same task is the classic race. Use SELECT ... FOR UPDATE SKIP LOCKED in Postgres, or a queue with native atomic-dequeue (SQS, RabbitMQ, etc.). Never rely on "check-then-update" in app code.
An agent who claimed a task and went to lunch shouldn't block it for 90 minutes. Auto-release claims older than a threshold (15–30 minutes for most UIs). Notify the agent gently before releasing.
You want to see: avg handle time, release rate, cherry-pick score. Not to punish, but to spot training needs and queue-shape problems.
Oldest waiting task. Count at risk of SLA breach. Agents online vs. capacity. Put this on a monitor the team can see.
Split a workload into parallel branches, process them simultaneously, then aggregate the results. Dramatically reduces processing time for batch operations.
