How would you describe an autocratic & a Narcisstic leadership style?

The autocratic leadership style focuses on the centralization of all the decisions to be made by the leader (dictatorship). Such leaders dont entertain any suggestions or initiatives from subordinates. As the decision is taken by only one person, it is easy to implement it & one can expect the results immediately, thus this style proves to be successful in terms of fast decision making.

In the Narcisstic leadership style, all the decisions revolve around the leader. The decisions at times can be constructive or destructive in nature. Such leaders are arrogant, dominating & egoistic in nature, which are narcissist characteristics.
