Today, weโll be exploring Nielsenโs 10 Usability Heuristics. These are essential principles that help us assess the usability of digital products. Letโs start with the first heuristic: โVisibility of system status.โ Can anyone tell me what that might mean?
I think it means that the user should always know what's happening in the app, right?
Exactly! Itโs about providing feedback to users about whatโs going on. Can anyone give me an example from an app?
Maybe when you upload a file, and it shows a progress bar?
Great example! That progress bar is a perfect illustration of keeping users informed. Letโs remember the acronym V.S. for 'Visibility of system status.' Itโs crucial in design.
Conducting a Practical Evaluation

Now, letโs try evaluating an app together. We will use the heuristics to fill out our standardized evaluation sheet. Who would like to suggest an app we could use?
How about Instagram? It's quite popular!
Perfect choice! Letโs focus on โMatch between system and the real world.โ Student_4, can you explain this heuristic?
This heuristic means using language and concepts that are familiar to the user instead of technical jargon.
Exactly! Can anyone think of a moment while using Instagram where this heuristic is followed or broken?
When it says โDMsโ instead of 'Direct Messages', some users might not understand!
Great observation! Let's record that on our evaluation sheet.
SWOT Analysis in Usability Evaluation

Having completed our heuristic evaluations, we now move on to conducting a SWOT analysis. What does SWOT stand for?
Strengths, Weaknesses, Opportunities, and Threats!
Correct! Letโs start with the strengths of the Instagram app. Student_3, what would you say is a strength?
It has a very user-friendly interface that is easy to navigate.
Excellent point! Now what about weaknesses? Student_4?
It often requires a good internet connection to load images quickly.
Great insights! Ensure you fill out your SWOT quadrants as we go along for our reports.
Feedback Theming

Finally, let's work on our feedback theming. We've collected user feedback on various features. How do we go about theming this feedback?
We can look for common phrases or ideas and group them together.
Exactly! This process is called affinity diagramming. Letโs take those 30 printed quotes and start clustering them into themes.
I see a lot of comments about user interface issues, maybe we can create a theme around that?
Good eye, Student_4! Let's definitely categorize that. Once we have our themes, we'll analyze sentiment next.
Sentiment Mapping

In our final session, we will perform sentiment mapping. What does this mean?
Itโs tagging the feedback as positive, negative, or neutral based on how users feel?
Exactly! After tagging, we can present our findings in a simple bar chart. How can this information aid us in design improvement, Student_3?
It helps prioritize what needs fixing based on user sentiment. If many users feel negatively about a feature, we should address that first.
Absolutely right! Remember, understanding user sentiment is crucial for our design decisions.
Introduction & Overview

Quick Overview
Standard
In this section, students learn to apply Nielsenโs 10 Usability Heuristics to evaluate digital interfaces. They will practice critiquing applications, using standardized evaluation sheets, conducting SWOT analyses, and theming user feedback to derive actionable insights for design improvements.
Detailed
Heuristic Evaluation Workshop
In this section, students engage deeply with heuristic evaluations as a means of understanding usability in digital products. They will examine Nielsenโs 10 Usability Heuristics, learning to critique known applications through structured evaluations. This process involves assessing the usability of interfaces and identifying critical areas where improvements can be made.
Using a standardized evaluation sheet, students will rate their chosen app against these heuristics, developing an understanding of the significance of each principle in real-world contexts. Additionally, they will conduct SWOT analyses on the evaluated products to gain insights into strengths, weaknesses, opportunities, and threats.
The workshop culminates with exercises on theming user feedback. By clustering user comments into themes and deriving sentiment analysis from them, students will learn how to extract actionable insights that inform design decisions. Understanding these concepts is crucial for bridging the gap between user needs and design outcomes.
