[Venkat]

Hi,

Could you please give explain the difference between PDM Method and the critical path method?

Thanks,
Venkat

Ok, let's try to understand this..

PDM is used to create schedule and sequencing activities, putting its dependencies and coming up with schedule network diagram. This is a perquisite to really go deeper and apply CPM to determine minimum project duration.

This is the reason PDM is a T&T for sequence activity process whereas CPM is a T&T for develop schedule. Without network diagram (using PDM as technique) we can't calculate critical path of the project and eventually can't estimate minimum project duration

Thanks a lot !
