In practise a design specification is a specific list of performance criteria that the final product must achieve in order to be successful.
It is not an accurate description of what the product must look like or be made of or how it works,
In schools this has traditionally been done under the headings of the acronym ACCESS FM (see bottom of page)
This has functioned very well for previous courses in product design, graphic products, and resistant materials since introduction in 1999. CHanges in courses post 2017 need take into account the need for Human Centred Design and global issues such as Sustainable Development Goals, the creation of a Circular Economy, new disciplines such as UX and UI design. So below is All DESIGN's first iteration of a new specification for The Great Recovery.
To ensure your specification is as thorough as possible you must create statements that state how the product must function, justify why you have said that by referring back to research, and then also say how you will test this at the prototyping stage.
