Prototyping is an approach to developing, testing and improving an idea at an early stage before you commit a lot of resources to it. The prototyping process outlined in this toolkit was developed by Nesta and thinkpublic.
It should be useful for any organisation or individual with a new untested idea. It will provide some background information on why to use prototyping, when, what and how to do it, and who to do it with.
Depending on what you are prototyping, you may find stages of this process are more relevant than others, but the diagram provides a framework which will allow you structure your approach.
