This presentation consolidates previously presented content:

• Application case of KLM-GOMS for operational improvements in management systems (first presented in 2008 at the Microsoft RAF event),
• Heuristics understood from principles of cognitive psychology (presented since 2015 in the UX Workshop).

In the User Centered Design process, it is crucial for all those involved in Design, Development, and Business decisions and execution to observe users operating with the product.

While user testing allows us to observe what needs improvement, it doesn’t provide concrete information on what we should modify in interfaces and interactions so that users can achieve their goals with greater effectiveness, efficiency, and satisfaction.

This presentation exposes Principles and Heuristics of perception, selection, and operation, as well as models for quantifying interaction costs (Hick’s Law, Fitts’s Law, KLM-GOMS) necessary to achieve better results.

In the User Centered Design process, it is crucial for all those involved in Design, Development, and Business decisions and execution to observe users operating with the product.

The application of these principles and tools allows for significant operational improvements in systems that are used recurrently. Reducing just 10 seconds of operation in a functionality used more than 100 times a day results in more than 15 minutes gained per day of operation, and more than 8 hours gained per month.

This increased operational efficiency leads to measurable improvements in productivity, quality of care, and user satisfaction with internal systems.
