Tier dispatch is the operational improvement over the single-interpreter call model. Instead of asking one interpreter and waiting, the system fans out the offer to a calibrated group and accepts the first qualified response.
A typical four-tier structure:
- Tier 1: Same-organization preferred interpreters (those who’ve worked for this buyer before), narrow language and specialty match, base rate
- Tier 2: Wider pool of qualified interpreters in same language and specialty, base rate or slight premium
- Tier 3: All qualified interpreters in the language, including ones who may need to travel or work outside their primary specialty, with a rate premium
- Tier 4: Manual operator-assisted dispatch where the operator finds an interpreter directly, with explicit buyer approval on the rate
The buyer never sees the tier-by-tier escalation; they see a fill. The interpreter sees an offer with the rate clearly stated. The operator sees the escalation state in real time and can intervene when needed.
Most well-tuned dispatch systems fill 90%+ of common-language requests at Tier 1 or 2, with only difficult requests (rare languages, short lead times, specialty constraints) reaching Tier 3 or 4.
