Question burst an alternative to rubber ducking

Rubber ducking, the exercise of explaining something to a rubber duck, is an easy way to get out of your own head and gain clarity by explaining your thoughts out loud.

Another excellent technique is called question burst. You explain your problem in 2 minutes and then others ask questions for 4 minutes.

Question bursts force you to create a high-level explanation quickly and then benefit from external perspectives through thoughtful questions.
