Business Context

Citizens benefit from personalized accessibility settings such as preferred language, font size, color contrast, voice interaction, and simplified navigation. These personalized experiences improve usability and digital inclusion. However, maintaining highly customized user interfaces can increase software complexity, testing requirements, and long-term maintenance costs. Municipalities must provide personalized accessibility while preserving manageable platform administration.

Smart CityTRIZ Resolution

Instead of creating multiple versions of the same application, municipalities should implement configurable accessibility preferences within a common platform architecture. User preferences are stored individually while the underlying software remains standardized and centrally maintained.

Applicable TRIZ Principles

Principle 6 – Universality uses a common platform that supports multiple accessibility configurations.

Principle 15 – Dynamics enables interfaces to adapt automatically to stored user preferences.

Principle 35 – Parameter Changes adjusts interface characteristics without modifying the core application.

Expected Outcome

Personalized user experiences

Simplified platform maintenance

Lower development costs

Greater digital inclusion

Decision Indicators

Early indicators that personalization is increasing maintenance complexity include:

Software updates require extensive interface modifications.

Accessibility features differ between applications.

Maintenance costs continue increasing.

User preferences are not retained across services.

Development teams duplicate accessibility functionality.

Monitoring these indicators supports scalable accessibility management.
