Critical Path Method

A network analysis technique used to predict project duration by

forward pass using a specified start date.

Arrow Diagramming Method

Category: Knowledge base > Dictionary

A network diagramming technique in which activities
are represented by arrows. The tail of the arrow represents the start and the head
represents the finish of the activity (the length of the arrow does not represent the
expected duration of the activity). Activities are connected at points called nodes
(usually drawn as small circles).

S-Curve

Category: Knowledge base > Dictionary

and end, steeper in the middle) produced on a project that starts slowly, accelerates,
and then tails off.
