Heuristic Evaluation Identifies Minor Usability Issues in Academic Information System
Category: User-Centred Design · Effect: Moderate effect · Year: 2022
Expert review using Nielsen's heuristics can pinpoint minor usability flaws in academic information systems, guiding targeted improvements.
Design Takeaway
Prioritize consistency in UI elements and provide clear feedback mechanisms to prevent minor user errors and enhance overall system usability.
Why It Matters
Understanding and addressing usability issues is crucial for the adoption and effectiveness of digital platforms. By employing heuristic evaluation, design teams can proactively identify potential user frustrations and areas for enhancement before they impact a broader user base.
Key Finding
The expert review found no critical usability problems, but did identify several minor issues related to consistency, error prevention, and user support, suggesting specific areas for refinement.
Key Findings
- No major usability issues were found in the SIAK-NG system.
- Minor usability issues were identified in heuristic principles Heu4 (Consistency and standards), Heu5 (Error prevention), Heu9 (Help users recognize, diagnose, and recover from errors), and Heu10 (Help and documentation).
Research Evidence
Aim: To evaluate the usability of the SIAK-NG academic information system using heuristic evaluation based on Jakob Nielsen's 10 usability principles.
Method: Heuristic Evaluation
Procedure: Three HCI and UI design experts evaluated the SIAK-NG system using a form based on Nielsen's 10 heuristic principles. They assessed severity rates for identified issues, and recommendations for improvement were derived from these ratings and HCI theory. Wireframes were created to suggest design revisions.
Sample Size: 3 expert evaluators
Context: Academic Information System (SIAK-NG)
Design Principle
Regularly apply heuristic evaluation with expert reviewers to identify and rectify usability issues early in the design process.
How to Apply
Conduct heuristic evaluations with 3-5 usability experts on your digital product, focusing on Nielsen's 10 heuristics, and use the severity ratings to prioritize fixes.
Limitations
The evaluation was conducted by a small number of expert evaluators, and did not involve direct end-user testing.
Student Guide (IB Design Technology)
Simple Explanation: Experts looked at a student information system and found a few small things that could be made easier for students to use, like making sure buttons and labels are always the same.
Why This Matters: This research shows how using expert opinions can help find problems in a digital system before real users get frustrated, which is a key part of making user-friendly designs.
Critical Thinking: How might the findings differ if the heuristic evaluation was supplemented with actual user testing? What are the trade-offs between expert evaluation and user testing?
IA-Ready Paragraph: This research demonstrates the effectiveness of heuristic evaluation in identifying usability issues within academic information systems. By employing expert reviewers against established principles, minor but impactful flaws in areas such as consistency and error prevention were pinpointed, leading to actionable design recommendations.
Project Tips
- When conducting heuristic evaluations, clearly define the scope of the system being reviewed.
- Ensure evaluators are familiar with the target user group and the system's intended functionality.
How to Use in IA
- Reference this study when justifying the use of heuristic evaluation as a method for identifying usability issues in your own design project.
Examiner Tips
- Ensure that the identified usability issues are clearly linked to specific heuristic principles.
- The recommendations for improvement should be practical and directly address the identified problems.
Independent Variable: Nielsen's 10 Heuristic Principles
Dependent Variable: Severity rate of usability issues
Controlled Variables: The specific academic information system being evaluated (SIAK-NG)
Strengths
- Utilizes a well-established usability evaluation method (Heuristic Evaluation).
- Provides specific, actionable recommendations for system improvement.
Critical Questions
- To what extent do the expert evaluators' backgrounds influence the identification and severity rating of usability issues?
- Are the proposed wireframe improvements sufficient to address the identified minor usability issues?
Extended Essay Application
- An Extended Essay could investigate the comparative effectiveness of heuristic evaluation versus user testing for different types of digital products.
- Explore how cultural context might influence the perception and severity of usability issues identified through heuristic evaluation.
