Criminal Justice Organization and Administration

In this unit, we learned about management, organizational structures, and open and closed systems. Write an essay in which you expand on the following topics.

1. Describe management, organization, and leadership in relation to criminal justice organizations. What are the main differences between management and leadership? How do managers and leaders have different roles in criminal justice organizations, and what can their impact be?
2. Explain the differences between closed and open systems. Where would a closed or open system model be a good fit in the criminal justice system?

Your response must be at least two pages in length, not including the title and reference pages, and include at least one outside source. Be sure that you include an introduction to your essay. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying APA citations.
