Delay to any of the activities sitting on the primary critical path will delay the finish date of the whole project. Any activity sitting on the path is critical even if its duration is only one day or one second.

Note however that for many years now, the introduction of the terms, secondary critical path, tertiary critical path, up to the nth path forces one to be clear when using the term. Suffice it to say, in this write up, we refer to the primary path when talking about critical path unless specifically described as another.

Identifying activities belonging to the primary critical path using the Primavera tool has three general setting; i.e. 1) Longest path, 2) Total float equal or less than zero, 3) Path with the lowest Total Float (maybe positive, zero or negative), or 4) whatever the contract defines it to be. The fourth one depends on how the governing contract defines critical. If the agreement says that all activities with Total Float less than 10 days are critical, then it is. All parties must respect that. The definition of Near Critical activities follows the same gist.
