1 Introduction to Usability and Usability Evaluation / What is Usability? Definition, importance, and the benefits of usability in the design process. / Usability vs. User Experience (UX): Understanding the difference and overlap. / The Usability Evaluation Process: Overview of the steps involved in conducting usability evaluation (planning, testing, analysis, and reporting). / Types of Usability Evaluations: Formative vs. summative evaluations
2 Usability Goals and Metrics / Usability Goals: Efficiency, effectiveness, satisfaction, and accessibility. / Common Usability Metrics: Task success rate, time on task, error rate, user satisfaction (e.g., SUS - System Usability Scale). / Quantitative vs. Qualitative Metrics: How to measure usability using both data types
3 Planning a Usability Evaluation / Creating a Usability Test Plan: Defining objectives, tasks, user profiles, and setting success criteria. / Recruiting Users: Identifying the right participants, including considerations for demographic diversity. / Selecting Usability Evaluation Methods: Choosing the best method based on context (e.g., remote testing, in-person, or moderated)
4 Usability Testing Methods (I): Think-Aloud Protocol and Task-Based Testing / Think-Aloud Protocol: How users verbalize their thoughts while performing tasks. / Task-Based Usability Testing: Developing realistic tasks for participants to complete. / Moderated vs. Unmoderated Testing: Pros and cons
5 Usability Testing Methods (II): Remote Testing and A/B Testing / Remote Usability Testing: Advantages, tools, and techniques for conducting usability tests remotely. / A/B Testing: Designing and analyzing A/B tests to evaluate two variations of a design
6 Heuristic Evaluation / What is Heuristic Evaluation?: An expert-based usability evaluation method. / Jakob Nielsen’s 10 Usability Heuristics: Overview of principles and how to apply them in evaluating interfaces. / How to Conduct Heuristic Evaluation: Identifying usability problems based on heuristics
8 Analyzing Usability Test Data / Analyzing Qualitative Data: Identifying key themes, problems, and patterns from user feedback. / Analyzing Quantitative Data: Interpreting success rates, task completion times, and error rates. / Synthesizing Data to Identify Usability Problems: Using data to inform design recommendations
9 Reporting Usability Evaluation Findings / Creating a Usability Evaluation Report: Structuring the report to include objectives, methods, findings, and recommendations. / Communicating Findings to Stakeholders: How to effectively present usability issues to designers, developers, and product managers. / Designing Actionable Recommendations: Ensuring that findings lead to concrete design changes
10 Usability Evaluation in Agile and Iterative Design / Integrating Usability Evaluation into Agile Workflows: How usability evaluations fit into iterative design processes like Agile and Scrum. / Fast Feedback Loops: Conducting quick usability tests and refining designs in short cycles
11 Ethical Considerations in Usability Evaluation / Ethical Principles in Usability Testing: Privacy, consent, and the protection of participant data. / Minimizing Bias: How to conduct objective usability tests and avoid influencing users’ behavior. / Inclusive Usability Evaluation: Ensuring that tests are accessible to all user groups, including people with disabilities
12 Model-Based Usability Evaluation: GOMS and Performance Prediction / Overview of GOMS and cognitive modeling. / Differences between GOMS and empirical methods (e.g., usability testing). / Use cases for GOMS in performance prediction and task optimization
