Which dependencies involve relationships between project and non-project activities?

TRUE/FALSE:

An activity or task is an element of work, normally found on the WBS, that has no fixed duration, no cost, and resource requirements.

TRUE/FALSE:

Activity duration estimating involves estimating the number of work periods that are needed to complete individual activities.

TRUE/FALSE:

Activity definition usually results in the project team developing a more detailed WBS and supporting explanations.

TRUE/FALSE:

In activity sequencing, hard logic refers to discretionary dependencies.

TRUE/FALSE:

In activity sequencing, soft logic refers to mandatory dependencies.

TRUE/FALSE:

In activity sequencing, external dependencies involve relationships between project and non project activities.

TRUE/FALSE:

The precedence diagramming method (PDM) is a network diagramming technique in which nodes represent activities.

The Program Evaluation and Review Technique (PERT) method of scheduling differs from the Critical Path Method (CPM) because the PERT method _____________________.

Uses weighted averages of activity durations to calculate project duration.

1. Project completion date
2. Contract date
3. Key event completion date

A Gantt chart is useful in determining ___________________.

When a task starts and stops.

The critical path is calculated by establishing the following dates: (4).

1. Early start
2. Early finish
3. Late start
4. Late finish

A(n) __________________ is an element of work, normally found on the WBS, that has an expected duration, a cost, and resource requirements.

Schedule ______________ involves controlling and managing changes to the project schedule.

Activity ______________ involves identifying and documenting the relationships between project activities.

Activity ____________ estimation involves estimating the number of work periods that are needed to complete individual activities.

________________ dependencies involve relationships between project and non-project activities.

________________ dependencies are defined by the project team.

_____________ dependencies are inherent in the nature of the work being done on a project.

A __________ occurs when two or more nodes precede a single node.

A __________ occurs when a single node is followed by two or more activities.

_____________________ activities have no duration and no resources but are needed to show logical relationships between activities.

What is the most common type of task dependency?

What is the critical path on a project?

The critical path is the series of activities in a project network diagram that determines the earliest completion date of the project.

PERT is a network analysis technique used to estimate project duration when there is a high degree of uncertainty about the individual activity duration estimates.

What is the first step in project time management?

Project time management involves the following 5 processes.

1. Activity definition
2. Activity sequencing
3. Activity duration estimating
4. Schedule development
5. Schedule control

What is activity definition?

Activity definition involves developing a more detailed WBS and supporting explanations to understand all the work to be done.

What is activity sequencing?

Involves reviewing activities and determining dependencies.

What are the 3 types of dependencies?

1. Mandatory dependencies - inherent in the nature of the work, hard logic
2. Discretionary dependencies - defined by the project team, soft logic
3. External dependencies - involve relationships between project and non-project activities.

What is a project network diagram?

A project network diagram is a schematic display of the logical relationships among, or sequencing of, project activities.

• Activities are represented by arrows
• Nodes or circles are the starting and ending points of activities
• Can only show finish-to-start dependencies

Precedence Diagramming Method.

• Activities are represented by boxes
• Arrows show relationships between activities
• More popular than ADM method and used by project management software.
• Better at showing different types of dependencies.

Which is better, ADM or PDM?

What is the activity duration?

Duration includes the actual amount of time worked on an activity PLUS elapsed time.

What are the important tools and techniques used in schedule development? (4)

1. Gantt charts
2. PERT analysis
3. critical path analysis
4. critical chain scheduling

Gantt charts provide a standard format for displaying project schedule information by listing project activities and their corresponding start and finish dates in a calendar format.

What is the Critical Path Method?

A project network analysis technique used to predict total project duration.

What is the critical path for a project?

The series of activities that determines the earliest time by which the project can be completed.

• The critical path is the LONGEST PATH through the network diagram and has the least amount of slack or float.

What is free slack or free float?

Is the amount of time an activity can be delayed without delaying the early start of any immediately following activities.

What is total slack or total float?

Is the amount of time an activity may be delayed from its early start without delaying planned project finish date.

What is Critical Chain Scheduling?

Is a method of scheduling that takes limited resources into account when creating a project schedule and includes buffers to protect the project completion date.

A buffer is additional time to complete a task.

What is a project buffer?

Additional time added before the project's due date.

What is a feeding buffers?

Additional time added before tasks on the critical path.

What does PERT stand for?

Program Evaluation and Review Technique.

PERT is a network analysis technique used to estimate project duration when there is a high degree of uncertainty about the individual activity duration estimates.

What is the formula for PERT?

PERT weighted average formula:

( optimistic time + 4X most likely time + pessimistic time ) / 6

Which type of dependencies are inherent in the nature of work being performed on a project?

Which types of dependencies are most common is project schedule?

Which is a similarity between project scope control and project schedule control?

Which of the following processes of project time management involves identifying and documenting the relationships between project activities?
