Non functional requirements mean how the product or system is supposed to be in terms of safety, security, usability and many more. They are very useful to make the product attractive or usable. They are used to enhance the quality of the product. These requirements should be properly overlooked or valued otherwise it may lead to failure. Look and feel requirements Look and feel requirements describe the intended spirit, the mood, the style of the product’s appearance. These requirements specify the intention of the appearance, and are not a detailed design of an interface. For example, Fibe TV should meet the designing standards.

Functional requirements refer to the things a feature should do. Company or the product is more conserned about this feature because this focuses on the future features and involves the image and reputation of the product for example Bell MTS is focused on the proper working of Features of Fibe TV.
