In any healthy team of professionals, there will occasionally be disagreement. Team members bring different perspectives, priorities, and risk tolerances, so they will advocate for different paths forward. This discord seems like an annoying roadblock until you realize it’s better than the alternative. Corporate cultures where a single suggestion is mindlessly accepted offer far fewer opportunities for refining and finding the best option available.
You don't have to give up efficiency or give up having a variety of opinions on the table. Healthy disagreement, respectful conversation, and finding a truly ideal solution are possible when you work toward inclusive leadership.
