Relevance of Usability Heuristics for User Interface Design to User experience.
Heuristic evaluation is a key part of designing a great product that users can easily engage with and find value in their interaction. It is a thorough assessment of a product’s user interface, and its purpose is to detect usability issues that may occur when users interact with a product, and identify ways to resolve them.
A breakdown the 10 of these heuristics in more detail:
- Visibility of System Status (users should know the system status at all times and get feedback on interactions with it);
- Match between system and the real world (the system should resemble the experiences that users already had);
- User control and freedom (users should be able to reverse their action if done by mistake);
- Consistency and standard (similar system elements should look similar);
- Error prevention (minimize the likelihood of making mistakes);
- Recognition rather than recall (users should be able to interact with the system without prior information or context;
- Flexibility and efficiency of use (both new and experienced users should be able to efficiently use the system);
- An aesthetic and minimalist design (declutter as much as possible, less is more);
- Help users recognize, diagnose, and recover from errors (make error messages understandable, and suggest ways to fix an error);
- Help and documentation (if a user has a hard time interacting with your app, make sure there’s help that’s easily accessible).
How to carry out Heuristics Evaluation
Here are the steps to ensure that your heuristic evaluation yields maximum results:
Step 1: Define the scope of your evaluation.
Ask yourself: What do I want to test?
Step 2: Know your end-user.
Ask yourself: Who is this product for?
Step 3: Choose your set of heuristics.
Ask yourself: Which usability principles should be followed?
Step 4: Set up an evaluation system and identify issues.
Ask yourself: How will evaluators assess and report a usability issue?
Step 5: Analyze and summarize findings.
Ask yourself: What do the findings show?
