What is a graphical network model that depicts a project’s tasks and the relationships between them?

Question

BlackTom AI · Accepted Answer

The prompt asks for a graphical network model that shows a project’s tasks and how they relate to one another. 
Option 1: Gantt chart. This is primarily a horizontal bar chart illustrating task duration and schedule over time, not a network of task relationships, so it does not depict the interdependencies in a network sense. 
Option 2: Critical path. While the critical path concept identifies the longest sequence of tasks determining project duration, it is not itself a graphical network model; it is a method used within scheduling analysis. 
Option 3: Dependency. This term refers to relationships or prerequisites between tasks, but it is not a named graphical representation or diagram type; it describes the concept more than a specific model that visually encodes the tasks and their links. 
Option 4: PERT chart. This is indeed a graphical network model (Program Evaluation and Review Technique) that maps tasks as nodes and their precedence relationships as directed edges, illustrating the sequence and dependencies among activities. 
Thus, the option that best matches the description of a graphical network model depicting tasks and their relationships is the PERT chart.

An activity with positive slack can be delayed without impacting the overall project completion time.

Assume that an activity can begin only after two other activities are completed. If the earliest completion time of one predecessor is twenty days, and the earliest completion time of the other predecessor is seventeen days, then the earliest start time of this activity must be twenty days.

Why do network diagrams typically precede Gantt charts in complex projects?

As a project manager of a construction project, you need to use a tool to routinely monitor project timeline against the baseline, update WBS and track schedule. Which of the following is the most appropriate?
