Who is referred to as the main target for the design of a service?

The main target for the design of a service is referred to as the Primary Persona. A Primary Persona represents the characteristics, needs, and behaviors of the ideal user for whom the product or service is being developed. This specific individual is typically based on user research and data collected from real users, ensuring that the design decisions are tailored to meet their requirements effectively. By focusing on the Primary Persona, designers can create a user-centric experience that aligns closely with users' goals and challenges, ultimately leading to better engagement and satisfaction with the service.

In contrast, the other options play different roles; the Target Audience encompasses a broader group rather than specifying an individual, while the Common User and Secondary Persona focus on different user types that may not represent the primary needs driving the design process. Therefore, the emphasis on the Primary Persona is crucial for a focused and effective design strategy.
