Which type of network diagram allows you to depict four types of dependencies (Finish-to-start, finish-to-finsih, start-to-start, and start-to-finish)?

A.
Precedence Diagramming Method (PDM)

B.
Gant Chart Diagram (GCD)

C.
Dependencie Diagram Method (DDM)

D.
Arrow Diagramming Method (ADM)

Explanation:
Precedence Diagramming Method The PDM shows nodes, representing activities, connected by arrows that represent dependencies. To represent that activity B is dependent on activity A. (in other words, activity A must be complete before activity B starts), simply draw an arrow from A to B. PDM diagrams are also referred to as activityon-node (AON) diagrams because the nodes contain the activity duration information. (You dont have enough information yet to complete all the
information presented here. Youll fill in the duration information during activity duration estimating.) In fact, nodes generally contain several pieces of information, including:

?Early startThe earliest date the activity can start
? DurationThe duration of the activity
? Early finishThe earliest date the activity can finish
? Late startThe latest date the activity can start
? Late finishThe latest date the activity can finish
? SlackDifference between the early start and the late start dates

You can represent four types of dependencies with a PDM diagram:

? Finish-to-start (the most common dependency type)The successor activitys start depends on the completions of the successor activity.
? Finish-to-finishThe completion of the successor activity depends on the completion of the predecessor activity.
? Start-to-startThe start of the successor activity depends on the start of the predecessor activity.
? Start-to-finishThe completion of the successor activity depends on the start of the predecessor activity

The PDM diagram in Figure shows eight activities, labeled AH. The arrows show how some activities are dependent on other activities. For example, activity B cannot start until activities A and C are complete. To show this dual dependency, you draw an arrow from A to B and another arrow from C to B.

Arrow Diagramming Method The arrow diagramming method (ADM) is similar to the PDM, except that all dependencies are finish-to-start. Also, durations are generally depicted on the arrows. For this reason, the ADM diagram is also called the activity-onarrow (AOA) diagram.
Dependencies are noted in a similar fashion to the PDM diagram, but there is another type of activity in ADM diagrams. Look at the dependency between node 3 and node 2. The arrow has a dotted line, which means the activity has no duration and is called a dummy activity. The purpose of dummy activities is simply to allow you to depict dependencies.

Gantt chart GCD is a type of bar chart, developed by Henry Gantt, that illustrates a project schedule. Gantt charts illustrate the start and finish dates of the terminal elements and summary elements of a project. Terminal elements and summary elements comprise the work breakdown structure of the project. Some Gantt charts also show the dependency (i.e., precedence network) relationships between activities
