Usability Testing Methods in Singapore

Usability Testing: Evaluating product usability, verifying product usability, helping to understand the quality of design (concept/idea) in a real-world scenario, and correcting deficiencies based on a list of test results. Suitable for testing and analyzing similar product usage, simulation design concepts, visual effects, and functional models.

Metrics: 1 easy to learn 2 easy to remember 3 use efficiency 4 low error rate 5 subjective satisfaction

Expert Evaluation, Expert Reviews: At least two designers or interaction design masters, by repeatedly using and testing the prototype to find the problem, adjust the design, modify the wireframe and update the prototype, add the details of the design.

Experts each find and list problems, associate them with corresponding laws, or find problems by law. Respectively to the question scoring, after the completion of the discussion and integration.

• 4 points – The problem is serious and the process is terminated and can not be resumed
• 3 points – the problem is more serious, it is difficult to recover
• 2 points – the problem is generally serious, the user can restore itself, the frequency of problems is low
• 1 point – the problem is small, occasional, not much impact on the user
• 0 points – no problem

Note: List the tasks that the prototype cares about, lest the expert not know which part of the prototype is interactive.

User Evaluation: To provide users with a prototype to complete a specific task, according to the user in the process of using the questions and suggestions for further changes.

• 1. To observe the user’s intentional or unconscious use, perceived ability (to receive or find clues to use), cognitive ability (understanding clues), these capabilities how to help users to achieve the purpose.
• 2. Invite those who did not participate in or rarely involved in the design evaluation, to avoid being affected by the known information, impact assessment, to ensure fair and objective results.
• 3. At the end of the day, a few qualitative questions may be asked about the direction of design and improvement of opinions, without disrupting the assessment process.
• 4. Recording, photos, videos and other forms of recording activities, to facilitate the exchange of later analysis, qualitative and quantitative research.

Note: A simple qualitative assessment generally requires 4-10 participants

The user’s opinion is not necessarily professional, intuitive feeling without careful consideration, the designer judge and re-examine the user’s opinion rationality.

Reasons:

• 1. Before seeing a specific product, it’s hard for users to know what they need;
• 2 users do not know what kind of product technology is feasible;
• 3. Difficult to unify the user needs, describe the demand, used to propose their own solutions, not necessarily seize the essence of demand

Commonly used evaluation method for Nielsen heuristic evaluation method (Nielsen Heuristic Evaluation)

Jakob Nielsen Ten Usability / Usability Laws:

1. System status visibility (Visibility of system status)

Let the user know what the system is doing

2. System and the real world of relevance matching (Match between system and the real world)

The system uses the user’s language, component/button label named reasonable, effective classification, specific location information is properly organized;

3. User control and freedom

Provide an “emergency exit” to leave the unintended state, support revocation and redo;

4. Consistency and standards (Consistency and standards)

Follow the platform or brand products unified norms;

5. Error prevention (Error prevention)

Avoid prone to error situations, prompts the user to check the confirmation before the actual action;

6. Recognition rather than memories, reduce the user’s memory burden (Recognition rather than recall)

Visualize objects, actions, and options to reduce user’s memory pressure;

7. Flexibility and efficiency of use

Common custom actions and quick default options, common projects easy to find new users, the effective completion of specific tasks;

8. Beautiful and minimalist design (Aesthetic and minimalist design)

Omit irrelevant or almost unwanted information, instructions clear and necessary;

9. Help users understand, diagnose errors, and recover from errors (Help users recognize, diagnose, and recover from errors)

Error messages are expressed in user language, accurately indicate the problem and proactively suggest solutions.

10. Help and documentation

First-time discoverability, easy to search, organize user tasks and list specific implementation steps.
