PDM question

Your company is designing the website. You have your activity list in hand and are ready to diagram the activity dependencies using the PDM technique. Which of the following statements is true?

  1. PDM is also the AON diagramming method and it uses one time estimate.

  2. PDM is also the AOA diagramming method and uses logical relationships.

  3. PDM is also the ADM diagramming method and its most common logical relationship is finishtostart.

  4. PDM is also the GERT method, which allows for conditions, branches, and loops

  5.  

The answer is A. I am confused if it uses  one time estimate

 

Like PERT - 3point (one activity have 3 time durations) 

or

Like Monte Carlo - Multitime iterative (repetitive)

 

PDM does not apply any such repetation. Only one duration per one activity.

That's it.

 Thanks Ji
