What Is User-Centred Design in IB Design Technology?

Weak examples:

• “Teenagers”
• “Students”
• “People who exercise”

Stronger examples:

• “A Year 10 student with limited hand strength”
• “An elderly user with reduced mobility”
• “A teacher working in a crowded classroom”

Specific users allow for meaningful design decisions.

Conducting Effective User Research

User-centred research should be relevant and purposeful, not excessive.

Effective research includes:

• Interviews or conversations with users
• Observations of users in context
• Targeted surveys focused on needs and limitations

Research should always inform design decisions. If research is not used later, it adds little value.

Translating Needs into Design Requirements

User needs should be turned into clear, measurable requirements.

For example:

• A need for comfort becomes an ergonomic requirement
• A need for accessibility becomes an inclusive design feature

This step is essential for linking research to design choices in both exams and coursework.

Testing with Users

Testing is a key part of user-centred design.

Effective testing:

• Involves real users whenever possible
• Focuses on functionality and usability
• Produces feedback that leads to improvement

Testing without acting on feedback is one of the most common reasons students lose marks.

Evaluating from the User’s Perspective

Evaluation should always return to the user.

Strong evaluation:

• Refers directly to user needs
• Uses feedback as evidence
• Acknowledges limitations honestly

Statements like “the product works well” are weak unless supported by user evidence.

User-Centred Design in Exams

In exams, user-centred design appears through scenario-based questions.

High-scoring answers:

• Identify relevant user needs quickly
• Justify decisions using those needs
• Evaluate trade-offs clearly

Ignoring the user in exam responses almost always limits marks.

Common User-Centred Design Mistakes

Students often lose marks by:

• Choosing users that are too broad
• Adding research without using it
• Designing based on personal preference
• Evaluating success without user feedback

IB rewards consistency, not volume.

Frequently Asked Questions

Do you always need a real user?

For the design project, real users are strongly recommended. In exams, hypothetical users are acceptable as long as needs are realistic and justified.

Is user-centred design more important than creativity?

Yes. Creativity supports user-centred design, but marks are awarded for how well a solution meets user needs, not how original it looks.

Can poor user-centred design cap your grade?

Absolutely. Weak user focus limits marks across multiple criteria, especially in evaluation and justification.

Final Thoughts

User-centred design is the backbone of IB Design Technology. Students who keep the user central at every stage write stronger exam answers, produce clearer design projects, and avoid common assessment pitfalls.

RevisionDojo Tip

RevisionDojo is the best platform for IB Design Technology students who want step-by-step guidance on applying user-centred design correctly in both exams and coursework. With the right structure and feedback, user-centred design becomes a strength rather than a source of lost marks.
