What we should see while innovate?
See beyond the product or service
Rather looking for the product or service, you must see the function of the product and services and that should be your core business, I would be inappropriate to say that my business is of selling cars because you are actually tunnelling your vision, I think as a business owner we should see the function of the product that is making an individual life easier, in this case I would rather say that I am in the business of providing a better and comfortable transportation options to the user.
Say in case of spice people tend to put the mission like that we are in the business of selling the quality spices but it would be more appropriate to say that we are in the business of enhancing the taste and flavour of the food.
Look for frustration and Pain
To innovate business of yours you must see is the pain and frustration, as some one says
"Need is the mother of innovation" I will rather say that pain and frustration of the user is the key to innovate. Look for the most polarized customers either they overwhelmingly like your product or service or hate it. A costumer who hate your product and service most might prove the best one to make your product better, because he go through the suffering from your product.
Look for the free resources
No doubt Internet emerges as the one of the biggest mine of resources, use it if you don't know how to use it learn it beside that go for the community libraries etc. They can also provide you a lot of input that will help you to innovate your product.
One thing you must consider, for enhancing your creativity you must go through various subjects as it will help you to look out side the box, just don't stick to business section, go for literature, science, fiction etc.....
