What are the general requirements for VI design? The more specific the better, what I do is about photography, please help me.

VI design is a visual identity system with logos as the main body. It does a series of designs related to logos, such as company stationery, umbrellas, work signs, flags, signs, and pens. . . Everything we use in our daily contact with the company can be designed. These designs must incorporate logos. This is called VI design.
