Start it on time and finish it on time.
Each person gets 2 minutes to update the status of his work to the rest of the team (what did I do yesterday, what am I doing today anx what are the issues I am facing.
Do not convert it into an issue resolution meeting
Very often the team members will talk to the senior most person in the group. In that case deliberately cut the eye contact with that person so that she will be forced to have eye contact with the rest of the team.
For issue resolution have separate meetings.
In case you are clubbing the scrum with the issue resolution meeting, formally divide the meeting into two and at the same time ensure that the scrum follows its rules.
Please remember that going for a meeting late or skipping an agreed upon meeting are not positive indicators of mutual respect.
If somebody violates the meeting norms anyone in the team can highlight it so that the correction happens then and there itself.
Every one must stand up during the stand up meeting.
