How This Pair Actually Operates
Boston and Kolkata operate on opposite sides of the workday, so forcing live meetings usually creates more fatigue than clarity.
Design the workflow around written handoffs, explicit SLAs, and a narrow exception path for urgent live calls.

Use a small escalation slot and treat the rest of the operating model as async handoff-driven.

Documented transfer lanes
This pair becomes useful when the handoff template, ETA, and response expectation are standardized.
