My answer on Quora to: What are the differences between sales and marketing? http://qr.ae/27AW
Sales and marketing are two entities used hand-in-hand; one fuels the other and they both promote and move the business. Failure to focus more on one entity is usually an indication of organizational structure thus the company/corporate goals. Sales markets the company every time they touch a potential or existing customer, same as marketing initiates a sales process with every research, analysis, planning and promotional activity. The common understanding of marketing is its power to either boost or drain sales by consuming the organizational resources; in which actually still remains as the only “myth”. Keeping the balance on organizational resources will show the differences between sales & marketing mainly by analyzing the past data and performance outcomes. A marketer at the end has to be a salesman as much as a salesman has to understand her/his stand on organizational marketing efforts. There are no differences but life-cycles in which every end is the start of the next sales/marketing effort.
