Liaising with Clients and Target Audiences

Introduction: Why communication matters in design

When students starts a design project in IB Design Technology SL, the best ideas do not come from guessing what people want. They come from listening carefully to the client, understanding the target audience, and checking whether the final product really solves the problem. 🤝 In design, a beautiful product is not enough. It must also be useful, suitable, and realistic for the people who will use it.

In this lesson, you will learn how liaising with clients and target audiences fits into the design project and practical programme. You will explore key terms such as $client$, $target audience$, and $end-user$, and you will see how designers use interviews, questionnaires, observations, and feedback to improve a product. You will also learn how this communication supports modelling, testing, development, and final evaluation.

By the end of this lesson, students should be able to:

• explain the main ideas and terminology connected to liaising with clients and target audiences,
• apply IB Design Technology SL reasoning to real design situations,
• connect this topic to the wider design project process,
• summarize why client and audience communication is essential,
• use examples and evidence to support design decisions.

Understanding the key people in a design project

A design project often involves several different groups of people. These groups do not all mean the same thing.

A $client$ is the person, organization, or group that asks for a design solution. The client may be paying for the product or may simply be the person who has requested it. For example, a school might be the client for a new storage system in a classroom.

A $target audience$ is the group of people the product is designed for. This group may be defined by age, ability, interests, lifestyle, or situation. For example, a water bottle designed for teenage athletes has a different target audience from one designed for elderly people with limited grip strength.

An $end-user$ is the person who actually uses the final product. Sometimes the client and the end-user are the same person, but not always. A parent may be the client buying a toy, while the child is the end-user.

This distinction matters because a design can only be successful if it meets the needs of the right people. A product that is attractive to the client but difficult for the end-user to use is not fully successful. 🎯

How designers liaise with clients and audiences

To $liaise$ means to communicate and cooperate with another person or group. In design technology, liaising with clients and target audiences means gathering useful information, checking ideas, and keeping communication open throughout the project.

This usually happens in several stages:

1. Identifying the need: The client explains the problem or opportunity.
2. Researching users: The designer studies the target audience and any end-user needs.
3. Developing ideas: Initial ideas are shared and discussed.
4. Gathering feedback: The client or users react to sketches, models, or prototypes.
5. Refining the design: The design is changed based on evidence.
6. Evaluating the result: The final product is checked against the original brief and user needs.

Good liaison is not just one conversation at the start. It is an ongoing process. If a designer only asks questions once and never checks again, the product may move away from what the client actually needs.

Common ways to liaise include:

• interviews,
• questionnaires,
• meetings,
• observation of users,
• surveys,
• focus groups,
• test sessions,
• feedback forms.

Each method gives different kinds of information. For example, a questionnaire may show what many users prefer, while an interview may explain why they prefer it.

Using evidence to understand needs

Strong design decisions depend on evidence, not guesswork. Evidence can come from direct user feedback, measurements, testing results, and observations.

For example, imagine students is designing a desk organizer for students. The client wants something compact, low-cost, and easy to produce. The target audience is secondary school students who carry many pens, chargers, and notes. If the designer only asks the client, they might miss important user needs such as space for large textbooks or compartments for cables.

To avoid this problem, a designer might ask students questions like:

• What items do you keep on your desk?
• Which storage problems do you experience most often?
• Do you prefer open storage or divided compartments?
• What size would fit your desk space?

This information helps create a design specification. A design specification is a clear list of requirements the final product should meet. It can include dimensions, materials, functions, safety needs, appearance, and cost limits.

For instance, the specification might include requirements such as:

• the organizer must fit within a desk space of $300\,\text{mm} \times 200\,\text{mm}$,
• it must hold at least $8$ pens,
• it must be made from sustainable materials where possible,
• it must be safe with no sharp edges.

Using evidence makes the design more accurate and more useful. 📊

Modelling, testing, and developing with client input

Client and audience liaison is closely linked to modelling, testing, and development. A model or prototype is a simplified version of the final design used to explore ideas and check performance.

In IB Design Technology SL, testing should not be random. It should be linked to the specification and to user needs. For example, if a chair is designed for a library, a test might check whether the seat height is comfortable for the target audience. If a lunch container is designed for younger students, a test might check whether the lid is easy to open and close.

During development, feedback from clients and target users can lead to improvements such as:

• changing the size,
• altering the shape,
• selecting a different material,
• improving the colour scheme,
• making controls easier to understand.

A simple example is a phone stand. The first prototype may hold a phone securely, but users might say the viewing angle is too steep. The designer then adjusts the angle and tests again. This cycle of $design \rightarrow test \rightarrow improve$ is a core part of the process.

This method is especially important because users often notice problems that the designer has missed. A product may look fine on paper but fail in real use. Testing with the correct audience helps find these issues early, when changes are cheaper and easier.

Communicating clearly in the design project

Communication in design is not only about speaking. It also includes sketches, annotated drawings, charts, specifications, prototypes, and evaluation notes. Clear communication helps the client understand what is being proposed and helps the designer record changes accurately.

Good documentation might include:

• a design brief,
• a list of user requirements,
• interview notes,
• survey results,
• annotated sketches,
• testing records,
• final evaluation.

When presenting ideas, it is important to use language that the client and audience can understand. Technical terms are useful, but they should be explained when necessary. For example, if a designer says a surface is $non-slip$, that should be shown with evidence such as material choice or test results.

Miscommunication can cause serious problems. If the client wants a product for outdoor use and the designer assumes indoor use, the final product may fail quickly in rain or sunlight. Good liaison reduces this risk by confirming requirements throughout the project.

This is why documentation matters so much. It creates a record of what was asked, what was changed, and why decisions were made. That record helps the designer justify the final outcome in the portfolio and final evaluation.

Conclusion

Liaising with clients and target audiences is a central part of IB Design Technology SL because design is about meeting real needs. students should remember that the $client$ is not always the same as the $end-user$, and that the $target audience$ may have different needs from both. Through interviews, surveys, observation, modelling, testing, and feedback, designers gather evidence that guides better decisions.

This process supports the entire design project and practical programme. It improves the quality of the design brief, makes the specification more realistic, strengthens development work, and leads to more successful final products. When designers listen carefully and respond to evidence, they create products that are more usable, more appropriate, and more likely to succeed in the real world. ✅
