As ever, it’s important to identify the cause. When it comes to technology, unless it’s complex, you can usually pinpoint a clear cause.

When it comes to people, there can be many reasons, but the catch is that you usually can’t ask the person concerned. In that case, you need to have a good relationship with them or be very brave. Well, there are of course tricks, such as how you ask the question.

Many teams have more or less "cloned" members. It's not good, but diversity is harder to work well. Are there any tips?

One tip is to strive for everyone in the team to be a world champion at something, i.e. the best in the team at something that the team needs from time to time. Then that member will feel in demand and thus important. This, in turn, makes you inclined to be humble about the competence of others in the team. In addition, if you have a common goal, which everyone has understood and accepted, then you have a good basis for countering destructive conflicts. Healthy conflicts always exist. The trick is to manage the conflicts in a balanced way related to everyone's needs.
