There are two kinds of PERT diagrams. One is the sort shown in the article, which has nodes denoting stages of the project and arrows denoting tasks. The other sort, which I did at college, has nodes denoting tasks and arrows denoting the dependencies between them. The nodes tend to be shown as boxes with task information in them - there are various formats, one of which is like this
| 14 | 3 | 17 |
| Do something | ||
|---|---|---|
| 19 | 5 | 22 |
where the boxes are
| early start | duration | early finish |
| Task description | ||
|---|---|---|
| late start | slack | late finish |
(I'm not sure if the "early finish" and "late start" boxes were this or the other way round.) -- Smjg 16:14, 31 Mar 2005 (UTC)
