Complex tickets are where a support team's consistency breaks. Two agents read the same case and one issues a credit while the other escalates. The cost shows up as inconsistent outcomes, slow handling times, and a QA process that argues after the fact.
Support Lead carries your tiers, escalation paths, SLAs, and refund rules, along with the promises agents are not allowed to make and the points where human approval is required. QA Reviewer turns that into response patterns, decision trees, QA checks, and escalation triggers, structured enough to plug into your tooling with classifications, next actions, and reviewer notes. The private instructions on each Context are where your policy lives, so the output reads like your team wrote it.
The same ticket gets the same handling on any desk. New starters get the decision tree instead of learning it from mistakes.
