By now the general principle for creating a Network Diagram should be clear. There are however additional rules for creating this sequence of activities. These are outlined below:
- Networks typically flow from left to right
- An activity cannot begin until all of its preceding activities are complete (the most basic relationship is the so called "Finish to Start" relationship)
- Arrows indicate precedence and flow
- Looping is not allowed- a Network Diagram is not a process flow
- Conditional statements are not allowed
- Use distinct start and finish tasks - start with one task, finish with one task (the general rule is, if you do not have a logical start and finish task, then create one)
The next blog will take the case example and create a coherent Network Diagra upon which the Critical Path calculation lessons will be based.
