What is a significant outcome of following the User Interface Design Guidelines?

Improved application accessibility is a crucial outcome of adhering to User Interface Design Guidelines. These guidelines are established to create interfaces that are intuitive, user-friendly, and inclusive for a wide range of users, including those with disabilities. By focusing on accessibility features such as proper contrast ratios, keyboard navigation, and screen reader compatibility, applications become more usable for everyone. This not only enhances user satisfaction but also broadens the potential user base, allowing more people to interact with the application effectively and efficiently.

The other outcomes listed do not directly correlate with the purpose of User Interface Design Guidelines. The guidelines are specifically aimed at enhancing user experience and accessibility, rather than inadvertently increasing costs, reducing software updates, or raising hardware requirements, which could detract from the overall design objective.
