- If anyone is remote for scrum, everyone is remote. Having one group of people in a room together with a few people video conferencing in is terrible for the remote folks. Instead, have everyone call in from their computers. It helps keep people from excluding those who are behind the screen.
- Get an occasional virtual coffee/tea with your workmates. Getting to know each other as people makes small conflicts and friction far less likely to turn into grudges.
- Pay attention to timezones. Even if the main office has more people, share the pain of bad timing across the team. Don't make the same person stay up late or get up early every scrum.
- The little things really matter during video calls. Don't eat near the microphone, circle back around to people who may have been interrupted, make sure everyone can hear clearly.
- Make an extra effort to get feedback and input from people. Especially for less outgoing or assertive folks, it's harder to break in to conversation on Slack or calls than in face to face interactions. Asking "[name], what are your thoughts?" a few times a call goes a long way.
