The "9 screens" matrix is a representation on a flat surface (sheet of paper, Excel® table, chart...) organized along two axes. The horizontal axis is a temporal axis, generally comprising three periods: past, present and future. The vertical axis is a systemic axis, also divided into three parts:
description of your midline system;
description of the subsystems that make it up on the low line ;
description of one (or more) "super-systems" on the top line.
Nine boxes are defined.
