What is BS EN 45550-2:2017?

BS EN 45550-2:2017 is a technical standard that defines the requirements for Human-centered design for interactive systems. It is part of the European standard EN ISO 9241 series, which covers various aspects of human-computer interaction.

Understanding the Scope

This standard focuses on ensuring that interactive systems are designed with human users in mind. It considers the needs, capabilities, and limitations of users, aiming to create products that are effective, efficient, and satisfying to use.

The scope of BS EN 45550-2:2017 includes the design of interactive systems across various domains, such as consumer electronics, software applications, websites, and industrial control systems. It applies to both hardware and software components, as well as the overall user interface.

The Key Principles

One of the key principles emphasized in BS EN 45550-2:2017 is user involvement throughout the design process. This means actively engaging users in different stages, from requirements gathering to prototype evaluation. By involving users, designers can gain valuable insights into their needs, preferences, and interactions with the system.

In addition, the standard emphasizes the importance of considering user characteristics, such as age, physical abilities, and knowledge level. Designers should ensure that the interactive system accommodates a diverse range of users and provides appropriate support for different user groups.

Evaluating Compliance

To ensure compliance with BS EN 45550-2:2017, a thorough evaluation process is recommended. Designers should conduct usability tests, expert evaluations, and user surveys to assess the overall user experience and identify areas for improvement.

During the evaluation phase, various usability metrics, such as efficiency, effectiveness, and satisfaction, can be measured. This allows designers to gather quantitative data and qualitative feedback that can inform design decisions and drive iterative improvements.
