The main launch of the study took place on 22 April 2010; 2.4 million UK mobile phone users were invited to participate. As of August 2010, 67,987 people were taking part in the UK arm of the study.

The first stage of the SCOT research methodology is to reconstruct the alternative interpretations of the technology, analyze the problems and conflicts these interpretations give rise to, and connect them to the design features of the technological artifacts. The relations between groups, problems, and designs can be visualized in diagrams.
