Also: Big Visible Charts
In Agile Software Development, the preferred way of displaying data visualizations is to post them on the wall in the team’s common workspace (i.e., rather than logging them in a spreadsheet). Examples of information radiators include a burn down chart, a burn up chart, and a task board, although other types of chart are possible. These may also be referred to as Big Visible Charts.
Keeping information visible at all times promotes transparency (one of the three legs of Scrum).
Alistair Cockburn coined the term “information radiator” in 2000, and introduced it in his 2001 book, Agile Software Development.
