The precedence diagramming method $($PDM$)$ is a technique used for constructing a schedule model in which activities are represented by nodes, and are graphically linked by one or more logical relationships to show the sequence in which the activities are to be performed. PDM includes four types of dependencies or logical relationships.

Match the concept to its appropriate definition.

Question $5$ options:

A logical relationship in which a successor activity cannot start until a predecessor activity has started. For example, level concrete $($successor$)$ cannot begin until pour foundation $($predecessor$)$ begins.

A logical relationship in which a successor activity cannot finish until a predecessor activity has finished. For example, writing a document $($predecessor$)$ is required to finish before editing the document $($successor$)$ can finish.

A logical relationship in which a predecessor activity cannot finish until a successor activity has started. For example, a new accounts payable system $($successor$)$ has to start before the old accounts payable system can be shut down $($predecessor$).$

A logical relationship in which a successor activity cannot start until a predecessor activity has finished. For example, installing the operating system on a PC $($successor$)$ cannot start until the PC hardware is assembled $($predecessor$).$
