What is ISO 24511:2018?

ISO 24511:2018 is an international standard that provides guidelines for the development and implementation of quality criteria to evaluate the usability of interactive systems. This standard aims to ensure that users can effectively and efficiently interact with software applications, websites, and other interactive systems.

Why is ISO 24511:2018 important?

Usability is a crucial factor in the success of any interactive system. Poorly designed and difficult to use systems can frustrate users, leading to decreased productivity and user dissatisfaction. ISO 24511:2018 helps organizations improve user satisfaction by providing a framework to assess and improve the usability of their systems.

Key principles of ISO 24511:2018

ISO 24511:2018 outlines several key principles that organizations should consider when developing and evaluating interactive systems:

Effectiveness: Interactive systems should enable users to achieve their goals accurately and completely. The system must provide the necessary functionality and support for users to successfully accomplish tasks.

Efficiency: The system should allow users to achieve their goals with minimal effort. It should minimize unnecessary steps, reduce processing time, and increase user productivity.

Satisfaction: Users should find the system enjoyable and satisfying to use. It should be aesthetically pleasing, intuitive, and provide a positive experience.

Learnability: Users should be able to quickly learn how to use the system. Clear instructions, helpful feedback, and an easily understandable interface are critical for reducing the learning curve.

Accessibility: The system should be accessible to users of diverse abilities. Considerations should be made for individuals with disabilities, ensuring that they can successfully interact with the system.

Applying ISO 24511:2018 to improve usability

To apply ISO 24511:2018, organizations can utilize various methods and techniques such as usability testing, user feedback collection, and iterative design processes. Usability experts can assess interactive systems against the principles outlined in the standard and identify areas for improvement.

By incorporating ISO 24511:2018 into their development workflows, organizations can create more user-friendly systems that meet the needs and expectations of their target users. Improved usability leads to increased user satisfaction, productivity, and ultimately, business success.
