Qualifications is probably not a good term. Its a word that more or less belongs to academia, job - seeking, etc type-of-thinking.
To start a business, you don't need one set of "qualifications" as such because you can always compensate for your weaknesses.
But if there are a few traits that I think would be important to do business, it would be the following:
- The strong desire and logical reasons to do the type of business one wants to do.
- One needs to be good problem solver. A lot in business involved solving one problem after another.
- One also needs to be independent because many times you have to do things alone despite what everybody else thinks. You do things because you have strong reasons why you want to do them even if you have to do it on your own.
- Further, you need to be nice and considerate of people because they are your customers, employees, partners and investors. If they don't like you, they won't do business with you.
