Design is at the heart of technology. this is why most technology courses include design. look at any
manufactured product, and you can see that someone has designed it: they have tried to make it look
good and work well.
the design process has several stages. it starts when someone notices a need or problem. it ends
when a product which meets that need or solves that problem is manufactured.
these are the stages of the design process:
• notice a need or a problem for example, when a cooking pot is heated, the handle becomes too
hot to touch. the designer may have to design a new product or change the product to improve it.
• write a design brief this is a simple, clear statement of what is needed. for example, design a
handle that stays cool when the pot is heated.
• investigate and research the designer asks questions and looks for information: who will use this
product? what will it do? how will it look? what materials can i use? what will the materials cost?
do they have the right properties (such as light weight and durability)? how will the product be
made? will it be safe?
• develop alternative solutions the designer thinks of various different ideas. he or she will then
draw sketches (simple drawings), of these different designs.
• choose the best solution the designer chooses the best design. he or she also considers cost, time
and whether it can be manufactured easily.
• make a model or prototype (also called the realization stage, when a design is made into a real
object) first, a detailed drawing is made, probably using cad software. then a prototype (a first
working model) is produced. or a computer simulation may be used.
• test and evaluate the prototype is physically tested to make sure it works and that it is strong
enough. then it is evaluated: how well does it meet the design brief? can it be improved?
• decide whether to manufacture if the final evaluation is positive, the company may decide to
manufacture the product.
