Plan B
Backup plan in case of challenges or lack of time
Every remote session needs a backup plan, because online the things that can go wrong are more numerous and less predictable than in a room.
A Plan B is not pessimism; it is professional preparation. In a physical workshop, most problems are visible and recoverable: the flipchart stand falls, you pick it up. Online, a single tech failure can freeze the entire session and there is no shared room to hold the group while you fix it.
A useful Plan B is specific, not generic. It covers the two or three scenarios most likely to actually happen: the collaboration tool goes down, the lead facilitator loses connection, the breakout rooms fail to open. For each, you decide in advance what you do, who takes over, and what you tell participants.
