The usability of the design can be improved by conducting user testing to gather feedback on the current design and identify any pain points or areas of confusion. This feedback can then be used to make iterative improvements to the design, such as simplifying navigation, improving the layout, and ensuring that key features are easily accessible. Additionally, incorporating user-centered design principles, such as clear and concise language, intuitive interactions, and responsive design, can also enhance the overall usability of the design. Regularly seeking input from users and incorporating their feedback into the design process will ultimately lead to a more user-friendly and effective design. **
