All you have listed are practically what every business by default knows but at the same time, while some succeeds some others fail and stop existing. Either way, one basic thing to have is understand the need you want to fill as a business inclined individual and clearly state your target market because without these every other thing becomes impracticable.
Of the 100% of businesses, only 5% remains successful as the remaining 95% have already given up and chose to just close shop. The key thing is to first know if there's a demand for such a service/product before starting to build one. That's basically what's wrong with those who closed shop: they haven't researched too much on their target market that's why they ended up in a flop. Also, from what I'm seeing on today's markets, one product goes in trend and many shops market the same product without innovation. That will greatly saturate the market ending up in great competition, so the best possible thing to do is to think of something unique before setting up your own shop. Innovation is a big edge in creating a business, as people would be curious in your product and end up trying it and *might* like it.
And I have to add, a businessman should also make character developments such as increasing his EQ. Those who can't take rejection will doom to fail. A person should also need to develop grit and confidence (not arrogance) whatever the situation is. I know someone who is confident, charismatic, and knows how to handle rejections and criticisms very well. Her business is terrible at first but because of these characteristics, she was able to make her business operational and stable. Market review is good and useful because it helps you identify where to start, but character development is better because it will help you keep your business.
