Design strategies
Introduction to design strategies
Designing is a complex process that requires creativity, innovation, and imagination. To create successful designs, you need to understand and apply different strategic approaches. There are four main design strategies that can help you develop effective solutions to design problems.
Each strategy offers a different way of approaching the design process, and understanding when and how to use them will make you a more effective designer. These strategies can be used individually or combined together depending on your specific design challenge.
The most effective designers often combine multiple strategies within a single project, adapting their approach as the design develops and new challenges emerge.
The four main design strategies
Collaboration
Collaboration is about working with others and drawing on their experience and specialist knowledge. This approach recognises that no single person has all the answers and that better solutions often emerge when different perspectives are combined.
You can collaborate with various people throughout your design process:
- Your client or the end users of your product
- Experts or professionals who specialise in your chosen materials or technologies
- Other designers or team members who bring different skills
The great thing about collaboration is that it can happen at any point in your design journey. You might collaborate during initial research to understand the problem better, when reviewing design ideas and prototypes, during manufacturing, or when evaluating your final design.
Professional Design Teams
In professional design environments, designers typically work in teams. This teamwork approach brings together a wider range of contributions and skills, and team members often inspire each other to think differently and more creatively.
User-centred design
User-centred design puts the end user at the heart of everything you do. This strategy focuses on gaining a deep understanding of who will actually use your product and what they really need from it. Rather than designing what you think looks good, you design what works best for the user.
This approach involves the user throughout the entire design and development process. You might collaborate with users during initial research to understand their needs, ask them to review your design ideas and prototypes, get their feedback during manufacturing, or involve them in evaluating your final design.
The key principle is that feedback from users should continue even after your product has been launched. User-centred design recognises that understanding user needs is an ongoing process, and successful products often evolve based on how people actually use them in real life.
A systems approach
A systems approach breaks the design process down into clear, manageable stages that follow a logical sequence. This methodical approach helps ensure that nothing important gets missed and that each stage builds properly on the previous one.
The process typically flows from developing the design brief and specification, through various design stages, and finally to evaluation at the end. However, this isn't just a straight line - feedback loops are built into the system so that testing or user feedback can inform and improve earlier stages of the design.
This systematic approach is particularly useful for complex projects because it helps you stay organised and ensures that each stage gets proper attention. The feedback loops mean you can constantly refine and improve your design based on what you learn at each stage.
Iterative design
Iterative design takes a cyclical approach where you continuously move through cycles of designing, prototyping, testing, and evaluating. Each cycle moves your solution forwards and helps resolve problems until you reach a finished design that works well.
This approach includes several key activities at each stage:
- Using client feedback on sketches, models, and prototypes
- Testing and field trials to see how your design performs in real conditions
- Evaluating each version of your design
The power of iterative design is that each iteration builds on what you learned from the previous one. Problems identified in testing lead to improvements in the next version. This continuous refinement process helps ensure your final design is as effective as possible.
Avoiding design fixation
Design fixation happens when you become too attached to your original design idea and can't see other possibilities. This can be a real problem because your first idea might not work exactly as you anticipated, but you become so focused on making it work that you miss better solutions.
Designing should be an imaginative, innovative, and creative process, but it doesn't always run smoothly. Sometimes your prototype doesn't work as expected, or testing reveals problems you hadn't considered. When this happens, it's important to stay flexible and open to different approaches.
Strategies to Avoid Design Fixation:
- Use a collaborative approach and actively seek advice from others who might see things differently
- Start with modelling or prototyping rather than detailed drawings, as this can help you spot problems earlier
- When you hit obstacles, go back to the original problem and try a completely fresh approach that might be more experimental
- Be willing to try different shapes, materials, or approaches rather than forcing your original idea to work
The key is maintaining flexibility throughout your design process and being willing to adapt when you discover new information or encounter unexpected challenges.
Key Points to Remember:
- Know your four strategies: Collaboration draws on others' expertise, user-centred design focuses on end-user needs, systems approach breaks design into logical stages, and iterative design uses continuous cycles of improvement.
- Collaboration can happen anywhere: You can work with clients, users, experts, or other designers at any stage of your design process.
- Users should be involved throughout: User-centred design means getting feedback from real users during research, development, testing, and even after launch.
- Stay flexible to avoid fixation: When your original idea isn't working, step back, seek fresh perspectives, and be willing to try completely different approaches.
- Combine strategies effectively: These four approaches work well together - you might use a systems approach with iterative cycles while collaborating with users throughout the process.
