Livework recently presented some great evidencing of the AT-ONE project in our monthly researchers meeting. Evidencing stands for tangible evidence, and is a means of rapidly producing service experiences at a very early stage of a project. Another term for evidencing is to produce archeology of the future, a means of looking back at something that hasn’t yet been created. More information about evidencing can be found here. Evidencing is related to paper prototyping but has several important differences. Firstly, evidencing has to look finished and convincing, whereas often a paper prototype is designed to look like a rough first draft. This is because the aim is to provide a convincing example of something ‘in the future’. Secondly, evidencing aims to give the experience of how the service will be experienced when completed. It is therefore strong on contextual information regarding its use. Thirdly, evidencing aims to lead by example, or pull a project, by making tangible the end point of the process. Finally, evidencing presents a solution in a holistic way, including branding elements, design elements, interaction elements and behavioural elements. A paper prototype is often product-focussed and therefore deliberately does not include non product elements.The photo above evidences the input to the Actor workshop and the output from the workshop. In addition, it shows similar document structures for the other letters of the AT-ONE method. Together they form the structure of the whole AT-ONE workshop process and show how they relate together.In a project consisting of multiple stake-holders, each focussed upon a different discipline, the evidencing gave us all a target to work towards, and was a great success.Sometimes it helps to start at the end!
