**NATURE OF SALES MANAGEMENT**

Originally, the term ‘sales management’ referred to the direction of sales force personnel. But, it has gained a significant position in the today’s world. Now, the sales management meant management of all marketing activities, including advertising, sales promotion, marketing research, physical distribution, pricing, and product merchandising.

The American marketers association (AMA’s) definition, takes into consideration a number of these viewpoints. Its definitions runs like: the planning, direction, and control of the personnel, selling activities of a business unit including recruiting, selecting, training, assigning, rating, supervising, paying, motivating, as all these tasks apply to the personnel sales-force. Further, it may be quoted: it is a socio-scientific process, involving’ group-effort’ in the pursuit of common goals or objectives, which are predetermined. Co-ordination is its key, though, no doubt, it is a system of authority, but the emphasis is on harmony and not conflict.

Sales-management differs from other fields of management, mainly in different aspects: the selling operation of a business firm does not exist in isolation. Thus, simultaneous with the changes taking place in the business, as well as marketing-orientation, a new concept of sales management has evolved. The business, is now society-oriented, on human-welfare aspects. So, sales-management has to work in a broader and newer environment, in co-existence with the traditional lines. The present emphasis is now on total development of human resources.
