The Sophi Heads-up Display (HUD) is an analytics tool developed for editors at Canada's The Globe and Mail newspaper that overlays relevant data about articles' performances onto The Globe and Mail website. We describe the motivation for our research, our design process (which includes initial needs assessment through semi-structured interviews with editors, and job shadowing), and the validation of features with users. We then discuss the ongoing iterations of the Sophi HUD and how its design was informed through collaboration with The Globe and Mail employees.
