ISO-IEC 19791:2016 is a technical standard that provides guidelines for evaluating and improving the usability of interactive systems. Usability refers to the design and implementation of systems in a way that makes them effective, efficient, and satisfying for users.
The Importance of ISO-IEC 19791:2016
ISO-IEC 19791:2016 plays a crucial role in ensuring that interactive systems are user-friendly. It helps organizations identify and address usability issues during the development process, ultimately resulting in products that better meet user needs and expectations. By following this standard, companies can improve customer satisfaction, reduce product support costs, and gain a competitive advantage in the market.
The Key Principles of ISO-IEC 19791:2016
The standard outlines several key principles that contribute to the usability of interactive systems:
Effectiveness: The system should enable users to achieve their goals efficiently and accurately.
Efficiency: The system should perform tasks with minimum resource consumption, such as time, effort, and mental workload.
Satisfaction: The system should be pleasant to use and provide an overall positive user experience.
Flexibility: The system should accommodate different user needs and preferences.
Learnability: The system should be easy to learn and allow users to quickly become proficient in its use.
How to Implement ISO-IEC 19791:2016
Implementing ISO-IEC 19791:2016 involves a systematic evaluation of the usability of interactive systems. This includes methods like user testing, heuristic evaluations, and expert reviews to identify usability issues and gather feedback from users.
Based on the findings, design improvements and recommendations are made to enhance the system's usability. Usability metrics can be used to measure the effectiveness, efficiency, and satisfaction of the system before and after implementing changes.
Regular usability evaluations and continuous improvement efforts are essential to ensure that the system remains user-friendly and aligned with evolving user needs and expectations.
In conclusion, ISO-IEC 19791:2016 is a valuable technical standard that guides organizations in creating interactive systems that are intuitive, efficient, and satisfying for users. By following the principles outlined in the standard and adopting systematic usability evaluation processes, companies can achieve enhanced user experiences, increased customer satisfaction, and improved market competitiveness.
