The fourth and final part of my "Reinventing..." series (see links at end of article) concentrates on a project portfolio rollup chart. Since this charting technique also includes and tracks business priority, I call this communication tool the "Project Barometer".
As with the previous articles, the chart attempts to maximize the amount of information a single diagram can communicate, without overwhelming the reader. However, unlike the previous techniques, which required the use of Visio, the barometer takes advantage of the simplicity of Excel.
