Group norms are the set of informal and formal ground rules that specify how people interact. The rules help members of the group determine how to behave. Advantages of clear ground rules within teams:

• Meetings and communication are more constructive.
• Teammates have a shared value system and work together to achieve goals.
• Everyone knows what is expected of them, and they live up to the expectations.
• Conflicts can be resolved more effectively and with understanding.
• New teammates can integrate more quickly.

Google researchers found that the ability to take risks in a safe environment was at the top of the list of group norms and made for happier, high-performing teams.

• Be present in conversations and use active listening skills.
• Show understanding. Recap discussion points and validate comments verbally.
• Be inclusive. Express gratitude for teammates, build rapport, and encourage feedback.
• Show confidence and conviction. State your decisions clearly and allow for vulnerability.

Group norms are most effective when everyone follows them. If everyone agrees to the norms laid out, it will be easier to hold each other accountable.

It is important to post your norms somewhere visible and refer to them often.

Every team has rules, but few are intentionally crafted. This could have a negative impact. For example:

• In a team of two, it's easy to create short back-and-forth emails. As more team members join, it becomes more complex keeping everyone in the loop. Emails may include reply-alls about weekend plans and real-time decision-making, leading to unread emails and lost information.
• A single individual dictates the rules for the group. He may inadvertently communicate late at night that can affect an entire company.

It's normal to expect that these rules will be bent or broken. The transition from unspoken to written norms can be smoother when it is decided in advance how to deal with the offense.

If you don't call attention to that norm, you inadvertently create a second set of norms. If a rule is expecting everyone to be on time and you don't point out when someone oversteps that norm, you're saying that it's not that important to be on time. Peer-to-peer enforcement with some humor is an effective way to enforce the norms.

They are not commandments set in stone.

It is valuable to continue to revisit them and change them as the team grows. Scheduling a meeting at regular intervals to provide feedback on the norms keeps the positive momentum going.

Creating norms requires the buy-in from most of the team members, including leadership.

The entire team needs to be engaged in the process for it to work very well.
