Choosing a client is one of the most strategic decisions in the IB Design Technology design project. A strong client can make justification, testing, and evaluation clear and manageable. A weak client, however, can quietly limit marks across the entire IA, even if the final solution looks impressive.

In IB Design Technology, the client is not just a name on a page. The client defines who the design is for, how decisions are justified, and how success is evaluated.

What Is a Client in IB Design Technology?

A client is the specific person or organisation experiencing the problem you are designing a solution for. The client provides:

• Real needs and constraints
• Feedback during testing
• Evidence for evaluation

The stronger and more realistic the client, the easier it becomes to demonstrate user-centred design and design thinking.

Why Client Choice Matters for IA Marks

Your client affects:

• The quality of your problem statement
• The relevance of your research
• The effectiveness of testing
• The strength of your evaluation

IB examiners reward projects where the client is clearly involved throughout the process. If the client feels artificial or vague, justification becomes weak and marks suffer.

Characteristics of a Good Client

The Client Is Specific and Real

Strong clients are real people or realistic organisations, not general groups.

Weak:

• “Students”
• “Gym users”
• “Office workers”

Strong:

• “A Year 10 student who cycles to school and struggles to carry books”
• “A teacher who frequently moves between classrooms with limited storage”

Specific clients lead to specific design decisions, which earn marks.

The Client Is Accessible

You should be able to communicate with your client easily.

A good client:

• Can answer questions
• Can provide feedback during testing
• Is available throughout the project

Clients who are unavailable or difficult to contact make user-centred design harder to demonstrate.

The Client Has Clear Needs

Strong clients experience genuine problems, not minor inconveniences.

IB examiners look for:

• Problems that affect usability, safety, comfort, or efficiency
• Needs that can be explored through research
• Issues that allow multiple possible solutions

Avoid choosing problems that are trivial or purely aesthetic.

The Client Is Appropriate for the Project Scope

The client’s problem should be:

• Manageable within the project timeframe
• Realistic with available resources
• Suitable for design investigation

Overly complex clients often lead to rushed solutions and weak evaluation.

Who Makes a Good Client?

Good clients often include:

• Teachers
• Family members
• School staff
• Students with specific needs
• Community members

These clients are usually accessible and willing to provide feedback, which strengthens testing and evaluation.

Who Makes a Poor Client?

Clients that often cause problems include:

• Yourself (unless carefully justified)
• Large, abstract groups
• Companies with no access to real feedback
• Hypothetical users with no evidence

While self-design is sometimes allowed, it is harder to prove objectivity and user feedback.

How Client Choice Affects Testing and Evaluation

Testing is one of the highest-impact parts of the IA. A strong client allows you to:

• Gather meaningful feedback
• Test against real needs
• Justify improvements clearly

Evaluation becomes far easier when you can refer directly to client responses rather than assumptions.

Common Client-Selection Mistakes

Students often lose marks by:

• Choosing clients that are too broad
• Selecting clients they cannot access
• Changing clients midway through the project
• Choosing a client to fit a solution rather than a problem

These issues weaken consistency and justification.

How to Check If Your Client Is a Good Choice

Before committing, ask:

• Can I communicate with this client regularly?
• Does this client have clear, real needs?
• Will this client allow meaningful testing?
• Can I justify design decisions using this client’s feedback?

If the answer is no to any of these, reconsider early.

Frequently Asked Questions

Can you use yourself as the client?

Sometimes, but it is risky. You must provide strong evidence and avoid bias. External clients are usually easier to justify and evaluate.

Does the client need to be an adult?

No. The client simply needs to be specific, accessible, and relevant to the problem.

Can changing clients lower marks?

Yes. Changing clients often causes inconsistency across the project and weakens justification.

Final Thoughts

Choosing the right client sets the foundation for a high-scoring IB Design Technology IA. A strong client makes research clearer, testing more meaningful, and evaluation far stronger.
