Arrow Diagram Example: Order Processing

The best way to understand Arrow Diagram is to look at some examples of Arrow Diagram and start drawing your own. You can now modify the Arrow Diagram example below using Visual Paradigm's online Arrow Diagram tool.

Time Estimation: Optimistic vs Pessimistic vs Most Likely

  • The optimistic estimate is based on everything that is associated with the project activity lining up correctly with absolutely nothing going wrong.
  • The pessimistic estimate assumes that everything that can go wrong will go wrong. This is also considered the worst-case scenario.
  • The most likely (or empirical) estimate is generally accepted as what a reasonable person would think the project activity would entail. This estimate assumes that there will be some obstacles to overcome but nothing that would completely derail the project.

This method can be very helpful when working with a person that is uncomfortable provided a single value for effort or costs, but is more comfortable with providing a range of optimist time, most likely time, and the pessimistic time.
