THE UX BASICS

Design Heuristics Evaluation

A heuristic evaluation is a usability inspection method for computer software that helps to identify usability problems in the user interface design.

Have you ever wondered how we get hooked to certain websites and spend hours without realising? Or, how it becomes so easy to navigate between some websites while with others it’s simply annoying even to identify the provided action items. So what makes these websites or products stand out? The answer to all these questions is a better User Experience Design. So grab a cup of coffee and let’s know, how, when and where we can use UX to make our products stand out by focusing on the User as the primary source of inspiration.

• Does Not need Users:

Accessing Severity

Prioritizing Problems

• Multiple Evaluators is Better

• The sweet spot is around 3–5 people

• Solove evaluation is also very valuable

Heuristic Evaluation vs User testing

• Heuristic Evaluation: Cheap and Fast,

• User testing: realistic, Find more issues, Assess UX better beyond usability

Evaluation needs to be focused on:

• Usability

• Task completion efficiency

• Learnability

• Memorability

• Mental effort

• Emotional measures

Advanced

• Analytic Evaluation

The goal of an analytical evaluation is to establish relationships between actual and benchmark data to determine whether variations exist.

• Heuristic Evaluation

A heuristic evaluation is a usability inspection method for computer software that helps to identify usability problems in the user interface design.

• Cognitive walkthrough

The cognitive walkthrough is a usability evaluation method in which one or more evaluators work through a series of tasks and ask a set of questions from the perspective of the user.
