Taking over the management of an existing team.
F: I hired 4 people for the last 3 years and 1 employee moved to another team, 2 employees quit and only 1 continued. What am I doing wrong?
R: How many people do you have in your team now?
F: 5, 1 who I hired and 4 previous managers hired.
R: Do you see something similar between you and the people you hired and the previous manager and people he hired. And what is different?
F: I don’t know.

Average managers play checkers, while great managers play chess. The difference? In checkers, all the pieces are uniform and move in the same way; they are interchangeable.
Manager = team.
The values that are important to the manager are important to the team.
The KPIs that are important to the manager are important to the team.
Manager ability to lead people, equal the ability of the team to follow manager.
The things you should know and have your opinion about:
Each person's strengths.
Triggers that activate those strengths.
His or her learning style.
Employee current goals.
Employee current goals as part of team and company goals.
Obstacles to success.
And questions that you should ask every employee when you replace previous manager:
What worked well with your previous manager?
What would your previous manager have done differently?
How do you like to receive feedback?
How can I help you?
What do you enjoy doing in your free time?
What is something you do outside of work that is important to you?
When you know all about your team members, try to hire people by their professional qualities your company needs and by the same life qualities your team has.
If you will choose people with different life qualities than your existing team will try to adopt these new qualities or will reject these qualities and create conflicts.
There's no black and no white. There are people who will cooperate with everyone, some not. There are people who will share with you what works and what doesn’t work, some not. There are people who will listen to you from the first time and support your goal, some not. You will need to take responsibility and solve the conflicts, continue to be in communication with your team and lead the things that are important to you and the company.
