OPMA Chapter 5 HW & LearnSmart

A firm should have a mix of projects that best support

a company's strategic strategy

Earned value management, when properly applied, provides:

a method for evaluating the success of a project.

The time-cost model attempts to

control expenditures,develop a minimum-cost schedule.

In the __ process of a project, the duration of an activity is reduced.

crashing

A schedule that lists all activities by their early start times is a(n)?

early start

Which of the following is not a direct activity cost?

penalty

The benefits of using project management software are

producing presentation ready reports and graphs,scheduling tasks and allocating resources,controlling costs.

The variance of an activity's completion time requires knowledge of

the optimistic time (a),the pessimistic time (b).

If the optimistic estimate of an activity's completion is 3 days and the pessimistic estimate is 15 days, what is the estimated variance (σ2σ2) of the activity's completion time?

4

When calculating the expected completion time, the most likely time is weighted ____ times more than the optimistic and pessimistic times.

4

You have estimated the following times for an activity a (optimistic time) = 2 days b (pessimistic time) = 12 days m (most likely time) = 4 days What is the expected time (ET) for this activity?

5

A statement of work (SOW) should include:

Completion steps or milestones,Work to be completed and proposed schedule,Budget performance measures

A work package includes which of the following elements?

Description of what is to be done,Performance measures,Starting and completion times for a group of activities

Which technique combines measures of scope, schedule and cost for evaluating project progress?

Earned value management

When calculating the critical path for a three time estimate project, you use the ______________ as the activity duration time.

Expected

When three time estimates are used to estimate the activity time, critical path calculation should use the __completion time for each activity.

Expected

True or false: Typically, a task is performed by multiple groups or organizations.

F

Slack activity time is the difference between the early start and the late finish of a project activity time.

False

True or false: There are relatively few project management software options for practitioners.

False

In a __ project structure, team members do not report to a dedicated manager, but remain part of their functional units.

Functional

When a project is housed within a functional division, such as manufacturing, it is called a ________ project.

Functional

To show the amount of time associated with an activity, as well as the sequence of activities, a project manager could use a __ chart

Gantt

In a network diagram, the activities that need to be completed directly before another activity are known as __ predecessors.

Immediate

The costs associated with sustaining a project are referred to as

Indirect

A schedule that delays each activity as long as possible without delaying the overall project completion is known as _____.

Late Start

A schedule that delays each activity as long as possible without delaying the overall project completion is known as _____.

Late Start Schedule

Which of the following is not a form of a matrix project?

Major

Which project organization structure uses team members who are assigned from the functional units and has a dedicated project manager?

Matrix

In CPM analysis it is generally expected that the relationship between activity direct costs and project indirect costs will be which of the following?

Negatively Related

The number of companies offering project management software is

Over 100

When breaking down a project into smaller elements, what terms are used to describe the subdivisions?

Task and subtasks

If a delay of an activity delays the entire project, then this activity

is on critical

The __ project structure minimizes the duplication of resources?

matrix

Which project organizational structure blends properties of functional and pure strategies?

matrix

When a single time estimate of an activity completion time is not reliable, you should use

Three Time Estimates

In a Gantt chart the horizontal axis is usually which of the following?

Time

A matrix project attempts to blend properties of functional and pure project structures.

True

Earned Value Management (EVM) has the capability to combine measurements of scope, schedule, and cost in a project.

True

The critical path in a project is that sequence of activities that consume the longest amount of time in a project network of activities.

True

Extending the critical path model to consider the trade-off between activity time and activity cost is known as the

time-cost model.

What term describes the group of activities assigned to a single organizational unit?

work package

Which of the following is needed to calculate the expected time (ET) of an activity?

Pessimistic time (b),Most likely time (m),Optimistic time (a)

Identify the type of project that primarily involves fundamental improvements to existing products.

Platform

Which of the following is a general type of project?

Platform,Derivative,Breakthrough

Which of the following is not a motivation for using a late start schedule?

Postponing the start of the entire project

All of the following are types of project organization structures except:

Process

A project where all members of the team work on the project full time is an example of which project organizational structure?

Pure

If you are part of a self-contained project team working full time on a project, you are most likely experiencing the ___ project structure.

Pure

Which project organization structure uses a self-contained team working full time on a single project?

Pure

You have been placed in charge of a large project. Shortened communication lines are required to ensure quick resolution of problems as they arise. You recognize that the project is going to take a lot of time and require a lot of team pride, motivation, and commitment by all members. Which project management structure should you use in this situation?

Pure Project

What term best describes the written description of the objectives to be achieved in a project?
