The Chartered Institute of Public Relations (CIPR) defines PR as the following: 

Every organisation, no matter how large or small, ultimately depends on its reputation for survival and success.

Customers, suppliers, employees, investors, journalists and regulators can have a powerful impact. They all have an opinion about the organisations they come into contact with - whether good or bad, right or wrong. These perceptions will drive their decisions about whether they want to work with, shop with and support these organisations.

In today's competitive market, reputation can be a company's biggest asset – the thing that makes you stand out from the crowd and gives you a competitive edge. Effective PR can help manage reputation by communicating and building good relationships with all organisation stakeholders.

The CIPR's definition of Public Relations:

"Public Relations is about reputation - the result of what you do, what you say and what others say about you.

Public Relations is the discipline which looks after reputation, with the aim of earning understanding and support and influencing opinion and behaviour. It is the planned and sustained effort to establish and maintain goodwill and mutual understanding between an organisation and its publics."
