To ensure diverse viewpoints in a team discussion about decision-making, start by fostering a safe and inclusive environment where everyone feels comfortable sharing their ideas. Encourage open-ended questions to stimulate discussion and invite diverse voices, actively seeking input from team members with different backgrounds and experiences. Promote active listening, allowing team members to fully engage with each other’s ideas. Rotating facilitators can also bring fresh perspectives and styles to the discussions. Finally, after decisions are made, take time to reflect on how diverse viewpoints shaped the outcomes, which can help improve future discussions.

To ensure diverse viewpoints are heard, I'd ask for each team member to give their thoughts. Before sharing, I'd ensure that everyone got five to ten minutes to write their answers down before ushering a discussion. The reason for the writing time is to give ample time for each person to write down their thoughts, their sharing pointers, in order that the discussion be more engrained in true personal reflection. Doing this will automatically ensure that everyone is involved in sharing their vantage points, from a overall level of cohesiveness and clarity.
