Merits of Precedence Diagrams - 2
Disadvantages
- Requires a lot of precise data
- Difficult to show time scale
- You can put the nodes on an approximate time scale
- Or stretch the node boxes like a bar chart
- But this confuses presentation of the node data
Bottom line
- The best method for establishing and calculating the network
- In the hands of a competent scheduler
- This method is used by most computer programs
- When done, present it as a bar chart anyway!
