After defining project activities, the next step in project time management is activity ____.

What is a Network Diagram in Project Management?

Whether you’re a project manager or a project team member, you should familiarize yourself with network diagrams — also known as the project schedule network diagram. A project network diagram is an important tool because it helps teams visualize the activities that need to be completed over the duration of a project. It also gives crucial context like task duration, sequence, and dependency.

What is a project network?

A project network is a graph that shows the activities, duration, and interdependencies of tasks within your project.

What is a project schedule network diagram in project management?

A project schedule network diagram visualizes the sequential and logical relationship between tasks in a project setting. This visualization relies on the clear expression of the chronology of tasks and events.

Most often, a project network diagram is depicted as a chart with a series of boxes and arrows. This network diagram tool is used to map out the schedule and work sequence for the project, as well as track its progress through each stage — up to and including completion. Because it encompasses the large tasks that need to occur over the project’s duration, a network diagram is also useful in illustrating the scope of the project.

Benefits of the project management network diagram

A network diagram allows a project manager to track each element of a project and quickly share its status with others. Its other benefits include:

• Visual representation of progress for stakeholders
• Establishing project workflows
• Tracking dependencies and potential bottlenecks

Research also shows that depicting data in a visual way can improve comprehension and enhance retention — meaning that a network diagram can boost performance and productivity while reducing stress among your team members.

Many information technology projects are failures in terms of meeting scope, time, and cost projections. True Managers often cite cost issues during the end phase of a project as one of their biggest challenges and the main cause of conflict. False Schedule performance can be estimated by subtracting the original time estimate from how long it really took to complete the project. True Individual work styles and cultural differences may cause schedule conflicts. True Different cultures may have different perceptions of work ethic. True The outputs to schedule development include activity duration estimates and project document updates. False The main outputs of estimating activity resources includes the activity list and attributes, project scope statement, milestone list, and organizational process assets. False Most managers are unfamiliar with any forms of scheduling. False Project schedules grow out of the basic documents that initiate a project. True It only takes one activity to complete a milestone. False Activity information is not a required input to the other time management processes. False After defining project activities, the next step in project time management is sequencing them or determining their dependencies. True Even though the delivery of new hardware may not be in the scope of a project, you should add an external dependency to it. True Network diagrams are the preferred technique for showing activity discretionary dependencies. False The arrows in a network diagram represent the activity sequencing or relationships between tasks. True It is not necessary to complete all of the activities on the network diagram in order for the project to finish. False Every item on the WBS needs to be on the network diagram. False Start-to-finish relationships are the most common type of relationships. False It is important that the people who help determine what resources are necessary include people who have experience and expertise in similar projects and with the organization performing the project. True

Duration only includes the actual amount of time worked on an activity. False In a Gantt chart created in Microsoft Project, a black diamond symbol represents a milestone. True A Tracking Gantt chart is based on the percentage of work completed for project tasks or the actual start and finish dates. True Most projects have one path through a network diagram. False The critical path always includes the most critical activities. False A fast and easy way to determine early and late start and finish dates and free and total slack amounts for activities is by using project management software. True Fast tracking can end up lengthening the project schedule. True By using the PERT weighted average for each activity duration estimate, the total project duration estimate does not account for the risk or uncertainty in the individual activity estimates. False One of PERT's main disadvantages is that it involves more work than CPM. True Many projects, especially in information technology, have very unrealistic schedule expectations. True Project management software does not have the capacity to automatically generate network diagrams and calculate the critical path(s) for the project. False There are ____ main processes involved in project time management. six ____ involves identifying the specific activities that the project team members and stakeholders must perform to produce the project deliverables. a.

Mandatory c. External b. Discretionary d. Internal Mandatory ____ dependencies are sometimes referred to as soft logic and should be used with care since they may limit later scheduling options. a. Mandatory c. External b. Discretionary d. Internal Discretionary ____ dependencies involve relationships between project and non-project activities. a. Mandatory c. External b. Discretionary d. Internal External ____ occur when two or more activities follow a single node. a. Combinations c. Merges b. Conflicts d. Bursts Bursts On a network diagram, all arrowheads should face toward the ____. a. top c. right b. left d. bottom right The ____ is a network diagramming technique in which boxes represent activities. a. PDM c. ADM b. AOA d. POA PDM
