The CEO of Tough Mudder believes that teams in his company are not working as effectively as they could, and he is asking you for advice. Provide the best answer to his question."Our teams in different countries have learned a great deal, so I am putting together an international team to study and share the best practices that have been developed. This team will have people from each continent where we operate. How should I plan to manage this team?"a. Speak about everyone on the team as though they are the same to help team members feel they are being treated equally. Do not single people out for special recognition.b. Understand that some people use online technology more than others and cannot be expected to participate as much. Accept that Internet culture often involves "trolling," or disrespectful disagreement, and do not interfere if this happens.c. Encourage team members to socialize online by sharing photos and videos. Reach out to people from cultures where proactively sharing ideas is not valued.d. To promote a sense of privacy, do not monitor online team communications. Keep information that may change frequently to yourself, as sharing it would be confusing

Get to know better every member of the different teams he is managing, this will help him learn about their strenghts and weaknesses, which is crucial for any manager.
Make sure the members of different teams know each other as well - it's not enough if the boss knows everyone well, coworkers should have at least some degree of familiarity with each other. This is what makes possible the development of synergies and better teamwork.
Make sure he treats people fairly - He should let his workers know that he will not be biased against anyone. Differences in performances will happen because everyone has different abilities, but people should be rewarded fairly, and according to merit.
