To be an effective manager means understanding your people and the situation.
Over the past several years I have been a consultant, working with various size companies (from small to midsize to corporate). Many managers tend to employ only one or maybe two of these management styles without much thought of the situation. I'm sure all of you have had some frustrations regarding this; when your team needed a leader to be Authoritative vs. Democratic.
Here is a great article describing management styles.
A great read, enjoy!
"The most appropriate style will depend on the people (their experience, values, motives) and the situation (stable/changing, new/seasonal team, short/long term focus). The key to being an effective leader is to have a broad repertoire of styles and to use them appropriately."
