What activity was on the critical path for building Disney's Animal Kingdom theme park

nine

What is the PERT weighted average based on an optimistic estimate of six days, a most likely estimate of eight days, and a pessimistic time of sixteen days?

guiding project execution

What is the first step in planning a project schedule?

finish-to-start

What is the most common type of dependency between activities?

parametric modeling

Which cost estimating technique would you be using if you estimate the cost of materials based on the number of square feet?

optimistic time

Which number should be shortest when creating a three-point estimate?

time-phased

A cost baseline is a(n) ____ budget that project managers use to measure and monitor cost performance

sequence activities

A project schedule network diagram is an output of the ___________ time management planning process.

optimistic

A three-point estimate is an estimate that includes a(n) ____, most likely, and pessimistic estimate, such as three weeks, four weeks, and five weeks, respectively

critical

A(n) ____ path for a project is the series of activities that determine the earliest time by which the project can be completed.

attributes

Activity ____ provide schedule-related information about each activity, such as predecessors, successors, logical relationships, leads and lags, resource requirements, constraints, imposed dates, and assumptions related to the activity

true

Activity sequencing involves reviewing the activity list and attributes, project scope statement, and milestone list to determine the relationships or dependencies between activities

true

After you determine the reason for a dependency between activities, you must determine the type of dependency (TF)

budgeting

Cost ____ involves allocating the overall cost estimate to individual tasks over time to establish a baseline for measuring performance

buffers

Critical chain scheduling considers limited resources when creating a project schedule and includes _________ to protect the project completion date.

true

Discretionary dependencies are defined by the project team

true

Duration relates to the time estimate, not the effort estimate

false

Every item on a WBS needs to be on the network diagram (TF)

30 weeks

If you have only two paths through a project network diagram where path 1 has a length of 20 weeks and path 2 has a length of 30 weeks, what is the estimated duration of the project?

bursts

In an AOA network diagram, ____ occur when two or more activities follow a single node.

merge

In an AOA network diagram, a(n) ____ occurs when two or more nodes precede a single node

false

It is poor practice to use more than one approach for creating a cost estimate

true

Lag time is a gap in time, such as waiting. (TF)

false

Most project teams use the most pessimistic time to estimate activity durations. (TF)

milestone list

Project teams often create a ____________ to ensure that all major activities are accounted for.

float

Slack or ____ is the amount of time an activity may be delayed without delaying a succeeding activity or the project finish date

true

The WBS is a required input to the cost budgeting process

WBS 100%

The _________ rule is that all work required for a deliverable is included in its sub-deliverables when defining activities

WBS

The ___________ must be the basis for a project cost estimate if you plan to create a cost baseline and use earned value management as part of monitoring and controlling costs

critical path

The ____________ method is a network diagramming technique used to predict total project duration

false

The critical path is the shortest path through the network diagram (TF)

fast tracking

The main disadvantage of ____ is that it can end up lengthening the project schedule, because starting some tasks too soon often increases project risk and results in rework.

schedule

The project team begins to develop a ____ by first clearly defining all the activities it needs to perform

true

There can be more than one critical path on a project

true

There is usually no cost or duration associated with a milestone (TF)

madatory

____ dependencies are inherent in the nature of the work being performed on a project.

analogous

____ estimates, also called top-down estimates, use the actual cost of a previous, similar project as the basis for estimating the cost of the current project

duration

____ includes the actual amount of time spent working on an activity plus elapsed time.

crashing

____ is a technique for making cost and schedule trade-offs to obtain the greatest amount of schedule compression for the least incremental cost
