While designers may have a clear vision for how a product or service should look and function, ultimately, it is the users who will determine whether or not it is successful. Designers must take into account the needs, preferences, and behaviors of their target users throughout the design process. This involves conducting user research, testing prototypes, and iterating based on feedback.
In essence, the design is never truly complete until it has been used and evaluated by real users. Their experiences and feedback can help to identify areas for improvement and inform future iterations of the design. Therefore, it is crucial for designers to prioritize user-centered design and continually gather feedback to ensure that their products and services are meeting the needs of their intended audience.
