REQUIREMENTS
Now you need to specify what you want your product to do.
Return to The Design Process
Functionality
Make a list of all the things your device must do. This is the minimum that will result in a viable product. Think about the intended use, and what product lifetime would be appropriate. Be realistic, do not over-specify the device, as this is likely to make it too difficult or too expensive to make. The result is called a Functional Specification. The more detail you can include the better.
Wish-list
It's a good idea to make a separate list of the non-essential, but desirable, things the device might do. At the design stage, the practicality of these will be considered, and if they can be incorporated economically, they may enhance the resulting product's sale-ability.
Requirements
This is where all the things the product needs to do are drawn up into a formal specification.
If necessary, this will include a detailed description of the functionality and any special mechanical or environmental requirements. The Requirements Specification needs to be as comprehensive as possible, to avoid problems and delays at the design stage.
If you are not able to draw up a Functional Specification, we can discuss this at the consultation stage.
