Many teams are constantly struggling to keep a clean and focused 15 minute daily stand-up meeting, but we cannot help asking our questions to the tech lead or senior members when an issue has been bugging us for the whole day. Others just talk too much and derail the conversation on important topics.
In such cases, you just can say “Greg, let’s allow everyone to explain their hurdles and complete the daily stand-up. We can save that for the sixteenth minute item”. After everyone talked about their impediments, we open the discussion and let them propose any matter they wanted to talk about. Make sure everyone is free to leave if the theme to be discussed is too specific to the work of other colleagues.
