To have great influence, an outside lobbying group must generally have one of two things: a lot of money or close relationships with executive branch officers. high visibility. detailed policy information. a committed membership a strong legal team.

The correct answer is a lot of money or close relationships with executive branch officers.

Lobbying, in politics, is, by definition, any and all practices exercised by people or companies to influence the decision-making spaces of the public power, acting both in the Executive and in the Legislative, being more frequent in this last mentioned sector. The group of people and institutions that seeks to influence public decisions is called a pressure group.

Basically, lobbying is a way of communicating, debating or trying to convince parliamentarians or government executives (in addition to close officials, such as advisers and secretaries) to make a decision to serve particular or general interests.

an informal structure in a bureaucracy would be something like so-called "office politics". where there's a formal structure set up for the organization, but then an informal subculture as well that has a way of organizing the bureaucracy further. this can be positive because it sets up an added degree of organization, albeit informal, within the bureaucracy.
