Answer:
There are many types of leadership styles and what works best for one group may not always work for the next. Depending on the style or preference it is best to observe the group you are working with to get a better feel of what is needed to improve or to do an expected job. The question is bit tricky because as a manager you will realize quickly that what works once doesn't necessarily mean it will work twice, no matter how tried and true the method is. Now as a whole, either you choose a great style and your work becomes flawless, or you chose a poor style of leadership and you will fail to grasp what you were trying to do. People are people and you need to remember that if you want positive results.
