Well, sure It is easy to disregard the importance of product development, especially if you personally believe that your product is great! Let me tell you, you are not the only one. Every business owner thinks that his business/idea/product is great. Otherwise, why are would you be in business, right?
Unfortunately, this self-centric opinion and rejection of reality can significantly damage the business at its core.
Alright, so how can you make sure you are not selling shit?
