Links, Lags and Ladders - the Subtleties of Overlapping Tasks

"Links, Lags and Ladders - the subtleties of overlapping tasks" by Patrick Weaver

Abstract:

This paper is designed to help explain the subtleties of overlapping tasks.

Logic in a Precedence Network Precedence diagrams use boxes to represent the basic network elements - the task (or activity).

Tasks have durations giving the period of time required to perform the work they represent and may have other descriptive data attached to them.

The other key element of precedence networks is the dependency (or link), which defines the logical relationship between the tasks. A link is shown in a precedence network diagram as a line.
