- The Pert chart is a tool of the competent and experienced manager
- that allows him to visualize the potential bottlenecks in his
- schedule, and to track his project's progress to make sure he
- isn't slipping badly because of a subassembly with development
- problems. Competent managers don't have to use this tool any more
- than they have to use spreadsheets, but it does make the job
- easier to use the proper tool. Really competent management, like
- the Japanese with their just in time methods, depend on Pert
- charts, or their equivalents, to spot potential trouble in their
- programs before it impacts their schedule. Trying to carry the
- schedule of a complex project in your head almost always results
- in some tiny but vital part of the program being overlooked until
- it's too late.

- be getting paid for this. :-)
