Explanation : An open house is a scheduled period of time
for which a house/organisation is open for
exploration by interested people/parties.
If a public sector organisation aims to
communicate with public by organizing an
open house, it will serve as an exercise for
publicity (process of creating public awareness
about the organisation), public relations (the
professional maintenance of a favourable
public image by the organization) and image
building (improving the public image or
opinion about the organisation)
Lobbying, on the other hand, refers to any
attempt to influence the decisions of the
government. It has its origin in the efforts
made to influence the votes of legislators,
generally in the lobby outside the legislative
chamber; and has come to acquire an
unavoidable presence in the political system
today.
