An Iterative Design Challenge
• To recognise user needs and identify potential gaps in the market.
• To understand how designers create solutions to user needs.
• To understand how designers evaluate the success of their designs and how they use this information to develop their designs.
To understand the different stages of the iterative design process.

The Iterative Design Process
Iterative design is a rigorous, reflective process, based on
evaluation and analysis. It is the step-by-step process by which a product is prepared
for manufacture.

The Iterative Design Process
Key Terms
Process - An ordered, systematic approach to a task.Iterative - Something that is done again and again, in order to improve it.Evaluate - To sum up and reflect on the effectiveness of a product.Analysis - To look at a product, or part of a problem, in detail or against criteria to find out more information.

Stages of the Iterative Design Process
A good designer can identify gaps in the market. They might spot that people are struggling with a particular task that could be solved through design of a new product. This understanding is called the context.
Explore: Recognising a Need
What is the problem here?What is the need?
Key TermsContext - The setting and nature of the design problem.Market - The intended user group that the designer is basing their research on.
The designer investigates the needs of the end user, understanding his or her life and considering how a solution to the problem would impact on them. Through careful analysis of the needs of the user and of existing products, a designer can begin to form an idea of what the solution should, or should not, be.
Explore: Understanding the User
Why do so many students experience this problem?
What other needs might the boy have?
What impact will the
solution have?
Why does he do that?
Who is he?
Where does he go?
When does he need it?
Through analysis of their research, designers understand what the solution needs to be or do to be successful. They can use this knowledge to form criteria to begin designing.
This design student has thought of thefollowing criteria to solve the boy’s problem:
• It must be lightweight
• It must be small enough for an 11-year-old to carry easily
• It must hold pens and pencils securely
Explore: Developing a Specification
Can you think of any other criteria for the solution?
Has this designer forgotten anything?
Designers often think ‘outside the box’. They look at the world around them, including nature, as a source of inspiration for their work.
Create: Initial Design Ideas
Why/how are these images relevant to this design problem?
Designers seek to come up with original, effective solutions – even if they are sometimes radical, or impossible! Any idea is a good idea at this stage. Some of the world’s best innovations have come from seemingly crazy ideas.
Create: Developing Ideas
Why should a designer not be afraid to record all of their ideas, no matter how strange?
Key TermsInnovation - an advancement or improvement on an existingproduct or way of doing something
Books
Lunch
P.E. Kit
Pens
Designers use drawing and modelling techniques to begin to test their ideas. They can try their ideas out through computer and three-dimensional modelling. These tests involve the user.
Create: Putting Together a Design Proposal
Why are paper and card models used at this stage of the design process?
A functioning prototype is expensive. How might the cost of this be recovered later?
Sports Kit
Reinforced area for books
Reflective Strip
Single strap school bag
Pencil case
Designers evaluate their findings. They question the purpose and the effectiveness of their proposal. They feed their findings back into the creative process and refine and test their ideas until the design meets all of the user’s needs.
Evaluate: Testing the Design Proposal
How many times should the iterative design process be repeated?Does evaluation only take place at the end of the cycle?
They use their findings to influence their designs as they repeat the design process.
Was the bag comfortable?
Did it carry all the items successfully?
Did my user like it?
Did their lunch get
wet?
How can it be improved?
