Flashcards in Chapter 3 Deck (47):
define work breakdown structure (WBS)
a hierarchical description of a project into more and more detailed components
define Gantt charts
planning charts used to schedule resources and allocate time
define program evaluation and review technique (PERT)
a project management technique that employs three time estimates for each activity
define critical path method (CPM)
a project management technique that uses only one time factor per activity
define critical path
the computed longest time path(s) through a network
define activity-on-node (AON)
a network diagram in which nodes designate activities
define activity-on-arrow (AOA)
a network diagram in which arrows designate activities
define critical path analysis
a process that helps determine a project schedule
define forward pass
a process that identifies all the early times
define backward pass
an activity that finds all the late start and late finish times
define slack time
free time for an activity. also referred to as free float or free slack
define optimistic time
the "best" activity completion time that could be obtained in a PERT network
define pessimistic time
the "worst" activity time that could be expected in a PERT network
define most likely time
the most probably time to complete an activity in a PERT network
shortening activity time in a network to reduce time on the critical path so total completion time is reduced
one of the current technology trends in services is

numerically controlled machines
time-independent communications or transactions are usually called
an operation where machine tools are changed automatically are known as
a machine center
One of the criticisms of ERP systems is that
ERP systems are inflexible once designed or a particular business
Organizations that provide services as a supplement to previously purchased goods and services are best described as
ERP is an outgrowth of
Integration of all aspects of manufacturing through computers is known as
computer integrated manufacturing
The elimination of mid-process steps or mid-channel organizations is called

The management of projects involves three phases:
Define project organization
an organization formed to ensure that programs (prjects) receive the proper management and attentio
Which of the following statements regarding Gantt charts is true?
Gantt charts are visual devices that show the duration of activities in a project.
Which of the following is true about AOA and AON networks?
1. In AOA, arrows represent activities.
2. In AON, nodes represent activities.
3. Activities consume time and resources.
4. Nodes are also called events in AO.
Slack time equals:
latest start - earliest start
The critical path of a network is the:
longest-time path through the network
PERT analysis computes the variance of the total project completion time as:
the sum of the variances of all activities on the critical path.
