Design specification

There are layers in a company's design specifications, which are generally divided into three levels: one is the company-level design specifications, which are mainly the company's overall user experience, brand, visual and other aspects; the second is a certain product line The design specifications of the product are mainly based on the first level to develop unified user experience, brand, visual and other specifications for several products on the product line; the third is the specific product design specifications, mainly for the The product is formulated with unified user experience, brand, and visual specifications, of course, on the basis of meeting the above two levels of design specifications.

The first purpose of the specification is to reduce the number of errors in the design process. Generally, this is for novice designers. Good quantitative indicators are to tell him experience.

B. Confirm the key points of the design: Obtain the key points within the scope of the design specification, including the design direction and design elements, in order to achieve closer cooperation with team members through the project design process.
