Internal-External Matrix

Internal-External Matrix (IE Matrix) is a nine quadrant, strategic planning analytical tool that places an organization's various divisions as circles in a display (similar to the BCG Matrix) based on two key dimensions: 1) the segment's IFE total weighted scores on the x-axis and 2) the segment's EFE total weighted scores on the y-axis. The diagram is divided into three major regions that have different strategy implications: 1) grow and build or 2) hold and maintain, or 3) harvest or divest.
