There are a number of different strategies which can be used to get powerful people to cooperate in terms of getting information, formal or informal approval to act, resources, introductions and support, according to Allan Cohen and David Bradford in their book Influencing Up. Even when a power gap seems intimidating or you have a negative relationship with a more powerful person, there are still things you can do to increase your chances of success.
The typical steps involved in influencing powerful people include:
Part II of the book provides a more detailed discussion of how to build a partnership relationship with your boss, in which you focus on helping your boss succeed in exchange for him or her providing the resources that you need. Part II discusses ways of influencing powerful people in general, including identifying what the powerful care about and how to gain access to them. Various stories of people who have succeeded in influencing powerful people help to illustrate the principles.
Many people feel uncomfortable with the idea of dealing with power and exercising influence, and would prefer to simply let their work speak for itself. The authors provide a convincing demonstration of why such an approach is inadequate, and they provide a very helpful range of ideas for negotiating even in toxic situations. Anyone who has ever experienced frustrations with management or difficulties in seeking resources from a powerful person will find the book very enlightening.
