4C - Identify the Relationships Between Activities

Question 1

A logical relationship that exists between two project activities.

Answer 1

activity dependency

Question 2

Inherent to the work itself. It is usually affected by physical constraints. Activities must be performed in a specific sequence for the work to be successful.

Answer 2

mandatory dependency (hard logic)

Question 3

Defined by the project and the project management team at their discretion. It is defined based on the best practices followed in a specific application area or on specific requirements. If there is no mandatory or external dependency between two activities, the team has some flexibility in activity sequencing.

Answer 3

discretionary dependency (soft logic) (preferential logic) (preferred logic)

Question 4

Contingent on inputs from outside the project activities.

Answer 4

external dependency

Question 5

Contingent on inputs from within the organization.

Answer 5

internal dependency

Question 6

The logical relationship between two activities that describes the sequence in which the activities should be carried out.

Answer 6

precedence relationship

Question 7

When sequencing two activities, the activity that must take place prior to the other.

Answer 7

predecessor activity

Question 8

When sequencing two activities, the activity that must take place after to the other and is driven by the relationship.

Answer 8

successor activity

Question 9

The identification of the dependencies of one activity over the other. It involves establishing the precedence relationships among activities and creating logical sequences.

Answer 9

dependency determination

Question 10

The precedence relationship between two activities where the predecessor activity must finish before the successor activity can start. It can be expressed as, “Activity A must finish before Activity B can begin.”

Answer 10

FS

Question 11

What does FS stand for?

Answer 11

Finish-to-Start

Question 12

The precedence relationship between two activities where the predecessor activity must finish before the successor activity can finish. It can be expressed as, “Activity A must finish before Activity B can finish.”

Answer 12

FF

Question 13

What does FF stand for?

Answer 13

Finish-to-Finish

Question 14

The precedence relationship between two activities where the predecessor activity must start before the successor activity can start. It can be expressed as, “Activity A must start before Activity B can start.”

Answer 14

SS

Question 15

What does SS stand for?

Answer 15

Start-to-Start

Question 16

The precedence relationship between two activities where the predecessor activity must start before the successor activity can finish. It can be expressed as, “Activity A must start before Activity B can finish.”

Answer 16

SF

Question 17

What does SF stand for?

Answer 17

Start-to-Finish

Question 18

A delay in the start of a successor activity.

Answer 18

lag

Question 19

A change in a logical relationship that allows the successor activity to start before the predecessor activity ends in an FS relationship.

Answer 19

lead

Question 20

A graphical representation of the sequence of project activities and the dependencies among them.

Answer 20

project schedule network diagram

Question 21

A project schedule network diagramming method that produces a type of project schedule network diagram that uses rectangular or circular nodes to represent activities and arrows to represent precedence relationships between activities.

Answer 21

PDM

Question 22

What does PDM stand for?

Answer 22

Precedence Diagramming Method

Question 23

A group of related activities that are reported as an aggregate activity.

Answer 23

summary activity (hammock activity)

Question 24

Activity sequences that must be revisited or repeated.

Answer 24

loop

Question 25

Activities that will be implemented only under specific conditions.

Answer 25

conditional branch

Question 26

A network diagramming method that allows for non-sequential activities such as loops or conditional branches.

Answer 26

conditional diagramming method

Question 27

An analysis method that provides a graphical display of the conditional and probabilistic treatment of logical relationships; it illustrates that not all the activities may ultimately be performed.

Answer 27

GERT

Question 28

What does GERT stand for?

Answer 28

Graphical Evaluation Review Technique
