Product design is a sum-up term used to describe the creation of the look and feel of a product that makes your product presentable. They help you to build identify, examine, and validate the problem your product addresses, then craft, design, test, and deliver the solution. This process consists of designing the latest life into existing ideas. Depending on your creation of an idea, the process can be different.
It helps designers to understand the user experience of a product as a whole, not purely the interaction (feel) or visual (look) part of the design. The goal of visual design is to ensure that the product conveys a sense of quality and proper response from its users. It examines all activities, communication, infrastructure, people, and material components involved in the service to improve both interactions between the provider and quality of service and its customers.
