4 Tony Doyle - University of Glasgow Questions from Science Committee 1.What has been achieved in the first year? See Oversight Committee (3): Executive Summary 2.How are the finances being spent? Broken down into 5 areas 3.Development in the medium-long term and resources required? GridPP I (09/01-08/04)Prototypeshort GridPP II (09/04-08/07)Productionmedium (09/07-) Exploitationlong-term
