What are the unique features of Sales, Marketing or Business Development Managers above other managers?

In my opinion, yes, he could be the best in any situation. Ask me Why?

Though the functions of Sales, Marketing, Business development are different but there is common goal among them to contribute volumes in terms of sales to the company. Their unique personalities include creative thinking / objection handling with clients. Their entire functions are profit centers in organisation..

Coming to other functions they are all support functions in organizing for organisational betterment..

You deal most of all with, and work for people . Instead of working with information and with people

The unique features should be:

• A vision creator.
• Understands their market and customers.
• Understands the fundamentals of branding, marketing and advertising.
• Stamina to work for long hours and meet deadlines.

This can not be the same person . A sales manager is a profile , a marketing manager is another profile , a business development manager is another profile . These3 functions demand very very different talents .
