Liaising with Clients and Target Audiences

Design projects work best when they solve a real need for real people. In IB Design Technology HL, liaising with clients and target audiences is the process of communicating with the people who will use, buy, request, or be affected by a product. students, this matters because a design that looks exciting on paper may fail if it does not match the client’s brief or the users’ needs. 📘

Objectives for this lesson:

Explain the main ideas and terminology behind liaising with clients and target audiences.
Apply IB Design Technology HL reasoning to client communication and user research.
Connect client liaison to the wider design project and practical programme.
Summarize why communication supports better modelling, testing, development, and documentation.
Use examples to show how client and audience feedback improves design outcomes.

A strong designer does not guess what people want. Instead, they ask questions, collect evidence, test ideas, and improve the product step by step. This is especially important in the individual design project, where the final solution must be justified with research and evaluation.

Understanding the Client, Target Audience, and End-User

The words client, target audience, and end-user are related, but they are not always the same. A client is the person, group, or organization that commissions the design or has the authority to approve it. The target audience is the broader group of people the product is intended for. The end-user is the person who actually uses the product.

For example, imagine a school asks a student designer to create a portable reading lamp for younger learners. The school may be the client because it sets the brief and approves the solution. The target audience may be students aged 11 to 14. The end-users are the students who will actually use the lamp at home or in class. If the lamp is too heavy, too expensive, or too complicated, it may fail even if the client likes the appearance.

To liaise effectively, students must understand all three roles. A product should satisfy the client’s requirements, suit the audience’s preferences and abilities, and work well for the end-user in real conditions. This is why design decisions are based on evidence rather than assumption.

Why Liaising Matters in the Design Project

Liaising means maintaining communication and cooperation. In design technology, it includes interviews, questionnaires, observations, meetings, emails, feedback sessions, and product reviews. These interactions are not extra tasks; they are part of the design process itself.

The most important reason for liaison is to make sure the problem is correctly defined. A brief may initially be vague, such as “design a storage solution for a classroom.” Through discussion, the designer may discover that the client needs something stackable, low-cost, easy to clean, and safe for younger students. Without liaison, the project might solve the wrong problem.

Good communication also helps the designer manage changes. During development, a client may request a smaller size, a different material, or a new feature. Target audiences may respond differently than expected when they test a prototype. This feedback helps the designer refine the solution. In IB Design Technology HL, this supports iterative development, where ideas are improved through repeated cycles of modelling, testing, and evaluation.

Real-world example: a student designing a phone holder for a study desk might discover through a short survey that users want cable management and adjustable angles. That information changes the design from a simple stand into a more useful study aid. 📱

Methods of Gathering Information from Clients and Audiences

Designers use different methods depending on the type of information needed. Each method has strengths and limitations, so students should choose carefully.

Interviews allow detailed answers. A designer can ask follow-up questions and clarify the client’s priorities. For example, an interview with a sports coach might reveal that a new equipment trolley must fit through narrow doors.

Questionnaires and surveys collect data from larger groups quickly. These are useful when the target audience is broad. Closed questions produce easier-to-analyze results, while open questions can reveal unexpected opinions. For example, a questionnaire about a lunchbox design may show that most users prefer lightweight materials and bright colors.

Observations show how people behave in real situations. Users may say one thing but do another. For instance, students may claim they want many compartments in a pencil case, but observation may show they actually prefer fast access and simple organization.

Focus groups are useful for comparing ideas. Several users discuss concepts together and react to visuals, models, or prototypes. This can reveal shared preferences and problems.

Testing and feedback sessions are especially valuable once prototypes exist. Users can try a model and report what works and what does not. For example, a chair prototype may feel stable in a sketch, but a user test may show that the seat height is uncomfortable.

In each case, designers should record evidence carefully. Useful data might include quotes, ratings, counts, photos, or notes. Good documentation makes it easier to justify decisions later in the final presentation.

Turning Feedback into Design Decisions

Collecting feedback is only useful if it changes the design. In IB Design Technology HL, designers must interpret information and turn it into clear design actions. This means looking for patterns, identifying priorities, and balancing competing needs.

Suppose a client wants a water bottle that is stylish, durable, and affordable. The target audience says they want a bottle that fits in a school bag and is easy to clean. These requirements may conflict slightly. A glass bottle may look attractive, but it can be heavy and fragile. A metal bottle may be durable but more expensive. A designer must compare options and explain choices using evidence.

This is where evaluation criteria become useful. Criteria might include size, cost, ergonomics, sustainability, safety, and appearance. If a prototype fails user testing because the lid is hard to open, the designer may adjust the threading, handle shape, or grip texture. If the client says the product is too large, the dimensions may be reduced. These changes should be documented so that the final solution can be traced back to user feedback.

A key IB idea is justification. It is not enough to say, “I changed it because people liked it better.” The designer should explain why the change improves performance, usability, or suitability. For example, “I reduced the handle width because several users with smaller hands reported discomfort during testing.” That statement uses evidence and links directly to a design decision.

Communication, Documentation, and Ethical Practice

Liaising is closely connected to documentation and communication. Designers need to present information clearly using sketches, annotated drawings, tables, charts, models, and digital presentations. Clear communication helps clients understand proposals and helps audiences respond accurately.

Documentation should show the design journey, not just the final product. Useful records include the original brief, research notes, survey results, meeting summaries, prototype photos, test results, and evaluation comments. This evidence demonstrates that decisions were informed by user needs.

Ethical practice is also important. When collecting information from clients or audiences, designers should respect privacy and be honest about how data will be used. If the audience includes children, the questions should be age-appropriate and not misleading. A designer should avoid manipulating feedback or only showing results that support a preferred idea. Accurate reporting is part of professional design behavior.

Communication must also be appropriate for the audience. A technical drawing may be useful for a manufacturer, but a client may understand a simple rendering better. Likewise, a younger end-user may respond better to a physical model than to a written specification. Choosing the right communication method is part of effective liaison. ✍️

How Liaison Fits the Wider Design Cycle

Liaising with clients and target audiences is not limited to one stage of the project. It appears throughout the design cycle.

At the research stage, liaison helps define the problem and identify user needs. At the idea generation stage, feedback helps choose the most promising concepts. During development, users test models and suggest improvements. In the final evaluation stage, the designer checks whether the completed product meets the brief and satisfies the client and audience.

In the practical programme, students often build skills through modelling, making, and testing. Liaison gives these activities purpose. A prototype is not just a model; it is a way to learn from users. A test is not just a classroom exercise; it is evidence that supports design decisions.

For example, if a student designs a modular desk organizer, early discussions with the client may establish the required number of compartments. Later, user testing may show that one compartment is too small for standard pens. The designer can revise the dimensions and document the improvement. This shows the full relationship between liaison, development, and final evaluation.

Conclusion

Liaising with clients and target audiences is essential in IB Design Technology HL because it connects design work to real human needs. By asking questions, gathering evidence, testing ideas, and documenting changes, students can produce solutions that are more useful, safer, and better matched to the brief. Effective liaison improves every stage of the design project, from research to final evaluation. It also strengthens communication, supports justified decision-making, and helps the designer work professionally and ethically. In short, good design begins and ends with people. ✅
