The success of any enterprise is base on the leadership. From this point the qualificaiton of the puiscance level will decide the destiney of a company. As one of the most important factors, revitalization make a great contribution to the development of enterprise. I basically agree with the contention of the speaker tnat the surest path to success is to alternate leadership.
The revitalization is like a exhilarant made the whole company full of enery which will surely promot the progress of development. Following the new leadership, the new idea and thought will bring into the company. For the continous fallen company, it is definitely a big turning point, and for those who keep the stable development, the brand new leadership will become the propulsion to step into the higher stage. The return of Jone bush change the diversity of apple in the depression age of pc through the inventional design of transparant colorfull crust. Apart of it, another significant meaning to the alternation of power will enact a vital role in guarding against the occupation happen. Due to the mightness of power in leader level, people is easy to harness their rights to gain the benefits for themselves. At the same time it also more or less decrease the incidence rate of bribe from the inferior empoyee. No one will permenatelly stay in a position, in that case every behaviors that attemp to depend on the relationship with the superior will be unable to actualize which has an important affect in the field of buisiness, politics and goverments.
On the contrary, we should also see the point that like the business enterprise the clients are always come from the personal relationship. One leadership step down may mean the loss of a group of  clients. For this purpose, the alternation may bring the negative influence as well. What's more, the new leadership also represant the a long duration of adjustment. The ferior employee need to suit the new way brought by the new leader, in which the frequent adjustment may casue the eficiency decrease either. And for the education institution, the alternation may lead the extinction of a project which not only waste the previous investment, but also strick the confidence of some professors. Besides some project may unable to create the achievment in a short time, like the reaserch of  new clear power use in the ordinary facilities, and the tolerance for the existanse of such project is necesseray to the human being. However, because of the limited time in leading position, people want to gaining as much honor as possible during his time, and those project that can bring the benefits in short time will be valued much more than the long term project which will become the resistance of the development to human society.
Dispite the darker side of alternation,  this kind of mode is not suit to every company. For a new founded company the alternation is unable to actualize. The founder has not established a stable foundation yet, and there is no people want to manage thus company, besides the power alernation may add the more unsteady element to its own growth. As a result the alternation of power should base on the compnay with a scale in some degree. And for those small company the stable powerness may more suit ot its develop. Moreover, the alternation is not always the best choise. Changing the environment of competence, creating a relaxed working atomosphere and establishing a better system of judgment the people will also bring the vigor to a company.
In the fianl conclusion, the leadership alternation is unable to accepted in every field and any scale of company. Despite the effective side, we should also see the problem it will bring Only through the entire consideration should we establishe a good judgment to this mode.
