ISO 23973 uses a reference model for web design comprising design, process and evaluation. The Standard itself is focused on the design domain aspects only. These are: purpose and strategy, content and functionality, navigation and interaction, and presentation and media design. These aspects can be seen as different levels of the overall design process.

The other two parts of the model represent the process domain and the evaluation domain. These constitute important aspects for the user-centred development of Web applications but they are not elaborated in this International Standard.
