Management styles are characteristic ways of making decisions and relating to subordinates. Management styles can be categorized into two main contrasting styles, autocratic and permissive. Management styles are also divided in the main categories of autocratic, paternalistic, and democratic. This idea was further developed by Robert Tannenbaum and Warren H. Schmidt (1958, 1973), who argued that the style of leadership is dependent upon the prevailing circumstance; therefore leaders should exercise a range of management styles and should deploy them as appropriate.
