Which practice can enhance the usability of business objects regarding their visual identity?

Using standardized icons significantly enhances the usability of business objects in terms of their visual identity. This practice creates a consistent visual language across different business objects, making it easier for users to quickly recognize and understand the functions and purposes of various icons. Standardization helps reduce cognitive load, as users don't need to learn a new set of symbols for each application or interface, leading to improved efficiency and a more intuitive user experience.

Additionally, standardized icons foster familiarity, which can increase user confidence and satisfaction. When users encounter familiar icons, they can navigate more easily, reducing the time needed to train or acclimate new users to the system. This consistency is particularly important in complex systems like Teamcenter, where numerous business objects are involved.

Other practices, such as eliminating visual elements or reducing the number of icons, could lead to a lack of clarity and make it more difficult for users to identify the functionalities they need. Limiting user access to icons would not enhance usability but rather restrict it, making it harder for users to interact with essential functions. Therefore, using standardized icons stands out as the most effective practice for enhancing visual identity and usability within business objects.
