The Mexican Statement

The World Assembly of Public Relations Associations gave its own definition of Public Relations
in Mexico in August 1978.

It said, "Public Relations is the Art and Social Science of analyzing trends, predicting their consequences, counseling organization's leaders and implementing planned programs of action that will serve both the organization and the public interests. 
A distinctive management function which helps establish and maintain mutual lines of communication; understanding, acceptance and co-operation between an organization and its publics; involves the management of problems or issues; helps management to keep informed responsive to public opinion; defines and emphasizes the responsibility of management to keep abreast of and effectively utilize change, serving as an early warning system to help anticipate trends; and uses research and sound and ethical communication techniques as its principal tools - Dr. Rex F. Harlon  1976
Public Relations is a combination of philosophy, sociology, economics, language, psychology, journalism, communication and other knowledge into a system of human understanding - Herbert M. Baus 
Persuasive communications to ensure that an organization gets the reputation it deserves, and guiding its behavior to help it deserve a good reputation - Warren Newman
Public Relations is the attempt by information, persuasion and adjustment to engineer public support for a cause or institution - Edward Bernays

The most important concept in the theory of games is the notion of a strategy. The formal definition is simple: A STRATEGY is a complex contingent plan for a player in the game.
The "complete contingent" part of this definition is what makes it powerful and, to some people, a bit confusing. By complete contingent plan I mean a full specification of a player's behavior, which describes the actions that the player would take at each of his possible decision points. Because information sets represent place in the game at which players make decisions, a player's strategy describes what he will do at each of his information sets.  Excerpts taken from STRATEGY-An Introduction to Game Theory- Joel Watson
A Brand, in essence, is a promise about who you are and what benefits you deliver that gets reinforced every single time people come in contact with any facet of you or your business
BRANDING isn't a veneer that you slap on (usually in the form of a new logo) to mask or transform a product offering.Treating branding like some skin-deep solution to your business's problems is like putting lipstick on a pig. People see through the makeup, no matter how thick the application. Branding has to go all the way to the core of who you are and what you stand for.
The big question  -'' So what is branding anyway? '' In a sentence, branding is the process of building a positive collection of perceptions in your customers' minds.
When people encounter your business's name, they automatically conjure up impressions and memories that determine what they believe about you.Their notions may be as a result of communications you've had with customers, or they may be the result of good or bad publicity or word-of-mouth. Your customers may have a deep well of perceptions about you, or your slate may be nearly clear of any impressions whatsoever.
Regardless of whether the beliefs a customer holds about you are many or few,good or bad,or accurate or inaccurate,they comprise the image of your brand in your customers's mind - and they influence how your customer thinks and buys.
Your brand image lives in your customers' minds whether you intentionally put it there or not. Branding is the route to making sure that the brand image you have is the brand image you want

The minute a marketer gets customers to believe 'our product is different and better and here's why', the marketer turns a commodity into a brand- and a better chance for sales success.Commodities are products that customers can't differentiate from one another because they all seem  to serve the same need,solve the same problem,and deliver the same value.
Want proof? Consider salt. Good old salt was epitome of a commodity until 1914, when Morton promised that its product would run freely even in damp weather. With the slogan 'When it rains,it pours'', Morton launched a brand and a branding success story that spices up university marketing course lectures to this day.
For more proof that you can brand and  differentiate nearly any product,look at the following examples of consumer brands that have distinguished themselves as leading choices in their product categories.
Soft drinks Coca-Cola
Water  Eva
Sneakers  Nike
Computers  Apple
Razor blades Gillette
Cake mixes  Betty Crocker
Suitcases Louis Vuitton
Automobiles Mercedes-Benz
Always brand your product if you want it to be noticed, differentiated, and viewed as more than a commodity.

Management comprises Planning, Organizing, Staffing, Motivating, Directing, Budgeting and Controlling - an organization for the purpose of accomplishing a goal.
In today's service-based knowledge economy,many companies are beginning to shift away from the traditional models of management,originally developed for productive systems.They are now requiring a broader range of managerial skills and styles that are adequate to diversity and to the dramatic,often discontinuous changes in the work environments- References and excerpts taken from Managing for Excellence in the Financial Institutions by Professor Prince Mike Ikupolati.
