This chart allows projects to be plotted in bubble format based on parameters that are selected for the x-axis, y-axis and bubble size. The purpose of this chart is to assess balance in the portfolio as shown in this product development example.  In this case the top left quadrant represents low risk, low financial return which is representative of typical product enhancement projects.  The bottom right represents high risk, high return projects which is representative of typical next generation product development projects that incorporate new technology.  The bottom left quadrant is high risk, low reward projects (which should be killed) and the top right represents low risk, high reward projects (clear winners).
