SUS (Scala di usabilità del sistema)

The System Usability Scale (SUS) is particularly advantageous in various sectors, including software development, healthcare technology, consumer electronics, and e-commerce, as it serves as a reliable tool for gauging user experiences across different applications. Used typically in the later phases of the design process, such as user testing or post-deployment evaluations, SUS can reveal how users perceive the usability of a product or system after real interactions, ensuring that design decisions align closely with user needs. Participation in SUS assessments is often open to a diverse range of stakeholders, including end-users, designers, usability researchers, and product managers, which helps in gathering varied perspectives on usability while promoting collaboration. Its straightforward nature allows teams to administer the questionnaire rapidly, yielding results that are easily interpretable and comparable against established benchmarks, enabling organizations to identify usability issues early or confirm successful design implementations. This methodology is extensively referenced in usability research and is frequently adopted in academic studies, making it well-suited for grant applications and compliance with industry standards focused on user-centered design practices, reflecting a commitment to delivering high-quality experiences that prioritize user satisfaction. The flexibility of the SUS allows it to be integrated into iterative design processes, where continuous user feedback contributes to product refinement, ultimately enhancing the likelihood of market success for innovative products.
