During the information searching stage of PMA,I know the trait theory, it says different people have different personal characters. this leads to they suitable for different kinds of leadership. This is the new information I gain. Thus the newest leadership theories maybe not is the one most suitable for the company. The leadership theory chosen should be suitable both company's current situation and the characteristics of managers. During the process to find a most suitable approach for Waveriders, I find it is not an easy thing to do. It takes me long time to compare and contrast the leadership approaches to find a most suitable one. Thus, if a company want to make some changes in management style, long time spent is one of the reason why the company give up the change on the half way. Thus, I suggest some leadership approach intermediary or suggestion center is necessary. There are several reasons for this recommendation. The first one is they are more familiar with the leadership theories, they can find a more suitable one than the company find by themselves. Secondly, they also can give some guide during the company changing process. Thirdly, they are the observer of the company. So they can see the question more objective. Fourthly, it also can save the company lots of time. However, based on my knowledge, there is small amount of leadership intermediary in CHina. So I think it is an opportunity to invest on an leadership intermediary.
