Where does one go to buy it? Do you have a website? Is the company set up to be worldwide? What experience does the company have? Can you produce 1000 on demand if needed? If so, how long does this take? Are there quantity discounts? Is the quality better than what is currently produced and does it cost more or less than what is offered? Has the product been field tested? How long has it been in the field? What type of support do you offer? Generally, what is your customer base like? If I wanted, could I just buy your chip as a P.I.D. controller and use it as a block in my own engineering design? Do you have manuals readily available for your product(s)? You do not have to have a product that does something new. The product can be an exact duplicate in function but have a different form and people will still buy it. These are some typical questions to ask yourself before actually releasing a product.
