One way to keep your Scrums on track is taken from soccer. Give each participant a yellow and red card that they can use at any time during the meeting. If someone gets off track, another Scrum participant can hold up a yellow card to warn them that they’re off topic or it isn’t adding value. If two or more people hold up a yellow card, the red card is in play – giving the speaker 60 seconds to wrap it up. When your team knows that they can play the cards at any time, it helps keep them focused and on-topic. Have you used this technique successfully or did it sink like a lead balloon? https://thinklouder.com/agile-yellow-red-cards/
