Selling is the profession-wide term, much like marketing defines a profession. Recently, attempts have been made to clearly understand who is in the sales profession, and who is not. There are many articles looking at marketing, advertising, promotions, and even public relations as ways to create a unique transaction.
Two common terms used to describe a salesperson are "Farmer" and "Hunter". The reality is that most professional sales people have a little of both. A hunter is often associated with aggressive personalities who use aggressive sales technique. In terms of sales methodology a hunter refers to a person whose focus is on bringing in and closing deals. This process is called "sales capturing". An example is a commodity sale such as a long distance sales person, shoe sales person and to a degree a car sales person. Their job is to find and convert buyers. A sales farmer is someone who creates sales demand by activities that directly influence and alter the buying process.
Many believe that the focus of selling is on the human agents involved in the exchange between buyer and seller. Effective selling also requires a systems approach, at minimum involving roles that sell, enable selling, and develop sales capabilities. Selling also involves salespeople who possess a specific set of sales skills and the knowledge required to facilitate the exchange of value between buyers and sellers that is unique from marketing, advertising, etc.
Within these three tenets, the following definition of professional selling is offered by the American Society for Training and Development (ASTD):
“The holistic business system required to effectively develop, manage, enable, and execute a mutually beneficial, interpersonal exchange of goods or services for equitable value.”
Team selling is one way to influence sales. Team selling is "a group of people representing the sales department and other functional areas in the firm, such as finance, production, and research and development". (Spiro) Team selling came about in the 1990s through total quality management (TQM). TQM occurs when companies work to improve their customer satisfaction by constantly improving all of their operations.
