6 Project Schedule Management

Question 1

The primary output of breaking down the

WBS work packages.

Answer 1

Activity list

Question 2

The identification of more than one
solution. Consider roles, materials, tools,
and approaches to the project work.

Answer 2

Alternative analysis

Question 3

A somewhat unreliable estimating approach that relies on historical information to predict what current activity
durations should be. It’s more reliable, however, than
team member recollections. It’s also known as top-down
estimating and is a form of expert judgment.

Answer 3

Analogous estimating

Question 4

The most accurate time-and-cost
estimating approach a project manager
can use. This estimating approach starts
considering every activity, its predecessor
and successor activities, and the exact
amount of resources needed to complete
each activity.

Answer 4

Bottom-up estimating

Question 5

A WBS entry that considers the time,
cost, and scope measurements for that
deliverable within the WBS. The
estimated performance is compared
against the actual performance to
measure overall performance for the
deliverables within .

Answer 5

Control account

Question 6

A predetermined range of acceptable
variances, such as +/–10 percent off
schedule. If the variance exceed, then project
control processes and corrected actions will be
enacted.

Answer 6

Control threshold

Question 7

A schedule compression approach that
adds more resources to activities on the
critical path to complete the project
earlier. Costs are added because the associated
labor and other resources cause costs to increase.

Answer 7

Crashing

Question 8

The path in the project network diagram
that cannot be delayed, otherwise the
project completion date will be late. There
can be more than one.
Activities have no float.

Answer 8

Critical path

Question 9

These dependencies are the preferred
order of activities. Project managers
should use these relationships at their
discretion and should document the logic
behind the decision. Allow activities to happen
in a preferred order because of best
practices, conditions unique to the project
work, or external events.

Answer 9

Discretionary dependencies / Soft Logic

Question 10

The earliest a project activity can finish.
Used in the forward pass procedure to
discover the critical path and the project
float.

Answer 10

Early finish

Question 11

The earliest a project activity can begin.
Used in the forward pass procedure to
discover the critical path and the project
float.

Answer 11

Early start

Question 12

As the name implies, these are
dependencies outside of the project’s
control. Examples include the delivery of
equipment from a vendor, the deliverable
of another project, or the decision of a
committee, lawsuit, or expected new law.

Answer 12

External dependencies

Question 13

A schedule compression method that
changes the relationship of activities.
Activities that would normally be done in
sequence are allowed to be done in parallel or
with some overlap. It can be
accomplished by changing the relation of
activities from FS to SS or even FF or by
adding lead time to downstream
activities. However, it does
add risk to the project.

Answer 13

Fast tracking

Question 14

An activity relationship type that requires
the current activity to be finished before
its successor can finish.

Answer 14

Finish-to-finish

Question 15

An activity relationship type that requires
the current activity to be finished before
its successor can start.

Answer 15

Finish-to-start

Question 16

A representation of a project network
diagram that is often used for outsourced
portions of a project, repetitive work
within a project, or a subproject. Also
called a subnet.

Answer 16

Fragnet

Question 17

This is the total time a single activity can
be delayed without affecting the early
start of its immediately following
successor activities.

Answer 17

Free float

Question 18

Logic that describes activities that must
happen in a particular order. For
example, the dirt must be excavated
before the foundation can be built. The
foundation must be in place before the
framing can begin.

Answer 18

Mandatory dependency / Hard logic

Question 19

Internal relationships to the project or the
organization. For example, the project
team must create the software as part of
the project’s deliverable before the
software can be tested for quality control.

Answer 19

Internal dependencies

Question 20

Positive time that moves two or more

activities further apart.

Answer 20

Lag time

Question 21

The latest a project activity can finish.
Used in the backward pass procedure to
discover the critical path and the project
float.

Answer 21

Late finish

Question 22

The latest a project activity can begin.
Used in the backward pass procedure to
discover the critical path and the project
float.

Answer 22

Late start

Question 23

Negative time that allows two or more
activities to overlap where ordinarily
these activities would be sequential.

Answer 23

Lead time

Question 24

A percentage of the project duration to
combat Parkinson’s Law. When project
activities become late, their lateness is
subtracted from the:

Answer 24

Management reserve

Question 25

These dependencies are the natural order of activities. For example, you can’t begin building your house until your foundation is in place.

Answer 25

Mandatory dependencies / Hard Logic

Question 26

A project simulation approach, predicts how scenarios may work out, given any number of variables. The process doesn’t actually churn out a specific answer, but a range of possible answers. It can examine, for example, the optimistic completion date, the pessimistic completion date, and the most likely completion date for each activity in the project and then predict a mean for the project schedule.

Answer 26

Monte Carlo analysis

Question 27

``` A quantitatively based duration estimate that uses mathematical formulas to predict how long an activity will take based on the quantities of work to be completed. ```

Answer 27

Parametric estimate

Question 28

``` A theory that states: “Work expands so as to fill the time available for its completion.” It is considered with time estimating, because bloated or padded activity estimates will fill the amount of time allotted to the activity. ```

Answer 28

Parkinson’s Law

Question 29

A WBS entry located below a control account and above the work packages. Signifies that there is more planning that needs to be completed for this specific deliverable.

Answer 29

Planning package

Question 30

``` A network diagram that shows activities in nodes and the relationship between each activity. Predecessors come before the current activity, and successors come after the current activity. ```

Answer 30

Precedence diagramming method

Question 31

Calendars that identify when the project | work will occur.

Answer 31

Project calendars

Question 32

This is the total time the project can be | delayed without passing the customer expected completion date.

Answer 32

Project float

Question 33

A diagram that visualizes the flow of the project activities and their relationships to other project activities.

Answer 33

Project network diagram

Question 34

An update to the work breakdown | structure.

Answer 34

Refinement

Question 35

``` This is a hierarchical breakdown of the project resources by category and resource type. For example, you could have a category of equipment, a category of human resources, and a category of materials. Within each category, you could identify the types of equipment your project will use, the types of human resources, and the types of materials. ```

Answer 35

Resource breakdown structure (RBS)

Question 36

Calendars that identify when project resources are available for the project work.

Answer 36

Resource calendars

Question 37

``` A method to flatten the schedule when resources are overallocated. It can be applied using different methods to accomplish different goals. One of the most common methods is to ensure that workers are not overextended on activities. ```

Answer 37

Resource-leveling heuristic

Question 38

The imminent work is planned in detail, while the work in the future is planned at a high level. This is a form of progressive elaboration.

Answer 38

Rolling wave planning

Question 39

A subsidiary plan in the project management plan. It defines how the project schedule will be created, estimated, controlled, and managed.

Answer 39

Schedule management plan

Question 40

The activities don’t necessarily have to happen in a specific order. For example, you could install the light fixtures first, then the carpet, and then paint the room. The project manager could use it to change the order of the activities if so desired.

Answer 40

Soft logic / Discretionary Dependencies
