[9-HI™ Dictionary] Quad Chart

A quad chart is a form of technical documentation used to briefly describe an invention or other innovation through writing, illustration and/or photographs. Such documents are described as "quad" charts because they are divided into four quadrants laid out on a landscape perspective. They are typically one-page only; their succinctness facilitates rapid decision-making. Though shorter, quad charts often serve in a similar capacity to white papers and the two documents are often requested alongside one another.
