Hello Stueti,

                   This is a very broad question and there may be different answers for different industries. For example medical device interfaces are different from telecommunications devices. In many cases there are IEC and prevailing counrty standards. Therefore, I am answering with a question:- What is the industry of focus for this product design and development?

Of course there would be a generalized process theory that is applicable, however I am not sure if this is what you are looking for?

Best Regards

Hi Stueti,

Product Interface Management is the primary role of a Product Manager in an organization. The key things for interface form his point of view are: Product design and development, Sales and marketing and many more. There are set rules and standards to achieve these interfaces.

Thanks and Regards,
