Ask E.T.: Project Management Graphics (or Gantt Charts) – came across this forum from a newsletter email from brucemaudesign. A fantastic forum discussion thread still active after 4 years!! Lots of posts from large civil projects to novels to movies to F1 teams regarding how to visualise the many interdependencies in managing multivariant projects – did they use a Gannt chart for the great wall of china.
From one of the posts a link to good PM resource from ex Columbia uni prof: http://www.projectreference.com/
