This type of analysis helps to determine the skeleton of the product or system in question. It does not deal with the form elements such as aesthetics, dimensions or materials. Its place is particularly relevant with a product that is radical and new in its invention. The designer must distance themselves from the problem The key question to ask when using this system is:
What is the new product to do and how could it do this?
It is a method that allows a designer to take a “Blue sky project” and create a brief that is much more manageable and focussed. It’s an energy saver of sorts.
