A qualified businessman can easily handle the problems arriving in the business.There are lots of responsibilities in the hands of a businessman towards consumers, suppliers, government, community, employees, etc. A qualified person has enough knowledge about different alternative technologies to improve the quality of products and reduce costs. He has specialized knowledge in the different fields of management.
Qualification is not necessary to succeed in business, but does help. Having something to show others will look good, but I think with the right person they are able to drive themselves to succeed no matter the obstacles. If they are really interested in the work they do they are more likely to succeed.
