Why are design guidelines important?

Design guidelines are sets of recommendations on how to apply design principles to provide a positive user experience. Designers use such guidelines to judge how to adopt principles such as intuitiveness, learnability, efficiency and consistency so they can create compelling designs and meet and exceed user needs.

What is the importance of design systems UI style guides and visual design principles in user interface design?

The primary benefit of design systems is their ability to replicate designs quickly by utilizing premade UI components and elements. Teams can continue to use the same elements over and over, reducing the need to reinvent the wheel and thus risking unintended inconsistency.
