Today we're diving into root cause analysis! Why do you think it's important to identify the root causes of problems in design?
I guess it helps us not just fix the surface issues but understand why they happen in the first place.
Exactly! By recognizing underlying issues, we can find more effective solutions. This is where methods like the Five Whys come in. Can anyone explain how that works?
You ask 'why' five times to dig deeper into the causes.
Great! Itโs a simple yet powerful technique. Now, letโs practice with a sample scenario about students missing event notifications. Why do you think this happens?
Maybe because emails get lost in their inbox?
Thatโs one reason! Keep asking why to uncover deeper layers. Whatโs next?
Maybe the notifications are not clear, or they're sent at a bad time?
Good observations! Remember, identifying these root causes can greatly enhance how we structure our design solutions. Let's summarize that: understanding deeper layers helps us address the real issues.
Research Planning

Moving on to research planning, why is it critical in design projects?
It helps us know what data we need and how to get it!
Exactly! Today, we will create a research plan. Letโs evaluate primary research methods like surveys and interviews first. Whatโs an advantage of surveys?
They can reach a lot of people quickly!
True! And interviews can give us detailed insights. What about the downsides?
Surveys might miss deeper insights, and interviews take more time.
Great analysis! For your plans, donโt forget to include a Gantt chart for scheduling. This will help you visualize the timeline for data collection. Does anyone know what a Gantt chart is?
It's a type of bar chart that shows a project schedule!
Exactly! This will help organize your tasks. Letโs summarize: a clear research plan is essential for design projects, ensuring we gather the right data efficiently.
Heuristic Evaluation

Next up is heuristic evaluation! This helps us assess the usability of products. Can anyone name a heuristic from Nielsenโs list?
One is 'match between system and real world.' I think it means using language users understand.
Correct! Using familiar language is key in design. We will compare a website against these heuristics. What might we look for in the evaluation?
We should see if itโs easy to navigate and if information is clear.
Exactly! And remember to assign severity ratings for any usability issues you find. This will guide necessary redesigns. Letโs summarize todayโs key point: heuristic evaluations help identify usability issues effectively.
Affinity Theming

Weโve covered evaluations; now let's analyze qualitative user feedback through affinity theming. Why do we cluster feedback?
To find common patterns and insights that can inform our design!
Exactly! We group feedback, identify themes, and summarize insights. For instance, if several users mention 'confusing navigation,' that could be a key design area to improve. How would you present these findings?
We can create a visual affinity map to show the themes visually.
Great thought! Visuals enhance understanding. Remember to propose design changes based on your themes. Let's summarize: clustering feedback reveals actionable insights for design improvement.
Specification Writing

Now letโs discuss specification writing. Why is this document important in design projects?
It outlines user needs and requirements for the design.
Spot on! A good spec provides a comprehensive view of the project. What elements should this specification include?
User personas, user stories, and prioritized requirements.
Exactly! Linking requirements to specific research data is key. It shows the rationale behind each design choice. Letโs summarize: a well-written specification is crucial for guiding the design process effectively.
Introduction & Overview

Quick Overview
Standard
In this section, students engage in various expanded exercises that deepen their understanding of design processes. Activities are structured to develop critical skills such as root cause analysis, research planning, heuristic evaluations, affinity theming, and specification writing. Each exercise is designed to consolidate learning objectives from the chapter, ensuring students can effectively interpret briefs and synthesize user feedback.
Detailed
Skills Development (Expanded Exercises)
In this section, students will engage in comprehensive exercises that foster their analytical and research skills within the context of design and inquiry. These exercises are designed to reinforce the concepts covered in the chapter, promoting a deeper understanding of how to approach design briefs and effectively gather and analyze data.
Key Exercises:
- Root Cause Analysis: In this exercise, students will apply the Five Whys method and fishbone diagrams to explore a local school-provided design brief, documenting their findings in a formatted diagram and a narrative. This skill enhances their ability to identify underlying issues in any design context.
- Research Planning: Students will develop a two-page research plan comparing three methods (surveys, interviews, and observations), including a Gantt chart for scheduling data collection and detailing ethical approval steps. This promotes a structured approach to planning research, considering time and methodology.
- Heuristic Evaluation: Students will evaluate a public website using Nielsenโs heuristics, assigning severity ratings and proposing redesigns. This fosters an understanding of usability principles and how they apply to iterative design.
- Affinity Theming: By clustering user feedback quotes and writing thematic summaries, students will learn to distill qualitative data into actionable insights, proposing design changes based on their findings.
- Specification Writing: Finally, students will draft user personas, user stories, and prioritized requirements, ensuring that all elements are linked to specific research data which reinforces the importance of evidence-based design.
These exercises not only enhance students' critical thinking but also prepare them for real-world scenarios in design thinking and user-centered design.
