“Indaba” (pronounced IN-DAR-BAH), comes from the Zulu and Xhosa people of southern Africa, and is used to simplify discussions between many parties.
When things got tricky at the climate-change summit in Paris, indabas where held at all hours of the day. An indaba is designed to allow each part to speak personally and state their thresholds, while also suggesting solutions to find a common ground.
This Quartz article describes indabas as a way to reach consensus, but to me it sounds more like consent.
