Out of the four topics I would say the first step in the four functions of management is organizing.
The first step of organizing would be self-organizing and time management. Without self-organizing your team will not be organized and will start going to other places for leadership. Once the self-organizing is done then the manager can start organizing the team.
Time management for your team should be a priority the team leader. The next step would be to develop a matrix and a chain of command. A clear chain of command will help organize the team.
In my opinion Planning is the second step. Without proper planning the team or workers will start making their own plans and those plans may not be want the manager wants.
While I was in the Navy I taught the people that worked for me that proper planning prevents poor performance. So Planning is an important step in management and leadership. A successful manager needs to have skill in setting objectives, goals and strategies. There are plenty of software tool that a manager can use. In the Navy we used what was called PMS boards.

LEADERSHIP STYLE TWO: The Mentor
The most interpersonally oriented of all the leadership styles, healthy Mentors are unconditionally caring leaders who derive deep satisfaction from seeing and encouraging the development of others; they are typically great supporters of customer service. Well-developed Twos will also be aware of their own needs, which provides balance in their lives and allows them to give freely, without expectation of return.
LEADERSHIP STYLE THREE: The Star
Star leaders are often expansive, risk-taking go-getters who ensure high productivity for their organizations. Formidable models for others, they are efficient and supremely goal-oriented; consequently, they tend to rise to top organizational levels, or to run their own companies.
