Flashcards in Chapter 3 Deck (47):
1

define work breakdown structure (WBS)

a hierarchical description of a project into more and more detailed components

2

define Gantt charts

planning charts used to schedule resources and allocate time

3

define program evaluation and review technique (PERT)

a project management technique that employs three time estimates for each activity

4

define critical path method (CPM)

a project management technique that uses only one time factor per activity

5

define critical path

the computed longest time path(s) through a network

6

define activity-on-node (AON)

a network diagram in which nodes designate activities

7

define activity-on-arrow (AOA)

a network diagram in which arrows designate activities

8

define critical path analysis

a process that helps determine a project schedule

9

define forward pass

a process that identifies all the early times

10

define backward pass

an activity that finds all the late start and late finish times

11

define slack time

free time for an activity. also referred to as free float or free slack

12

define optimistic time

the "best" activity completion time that could be obtained in a PERT network

13

define pessimistic time

the "worst" activity time that could be expected in a PERT network

14

define most likely time

the most probably time to complete an activity in a PERT network

15

define crashing

shortening activity time in a network to reduce time on the critical path so total completion time is reduced

16

one of the current technology trends in services is

the shift away from time-dependent transactions

17

integration of design and production of a product through the use of a computer is known as

computer-aided design and manufacturing system

18

programmable machines that can perform multiple functions are known as

industrial robots

19

which of the following is used to improve organizational performance by providing the information required for effective decision making?

decision support system

20

to properly integrate new technology into their organization, a firm should realize that

customer training in the use of the technology will may be necessary

21

manufacturing equipment that is directly controlled by a computer is known as

numerically controlled machines

22

time-independent communications or transactions are usually called

aynchronous

23

an operation where machine tools are changed automatically are known as

a machine center

24

One of the criticisms of ERP systems is that

ERP systems are inflexible once designed or a particular business

25

Organizations that provide services as a supplement to previously purchased goods and services are best described as

customer support

26

ERP is an outgrowth of

MRP

27

Integration of all aspects of manufacturing through computers is known as

computer integrated manufacturing

28

The elimination of mid-process steps or mid-channel organizations is called

disintermediation

29

A software system that focuses on the interface between the customer and the firm is called

customer relationship management

30

Which of the following manages a firm's technology assets by making the right data available on demand?

management information system

31

A manufacturing facility that is automated to some extent and produces a wide variety of products is known as

flexible manufacturing system

32

Prior to the introduction of ERP

each functional area had their own software and database

33

Organizations that provide remote services to customers are best described as

Application Service Providers

34

Which of the following statements about self-service operations is TRUE?

many firms use discounts to entice customers to use self-service channels

35

Which of the following statements about EDI is TRUE?

EDI is very fast

36

Which of the following had the fewest restrictions in terms of access?

internet

37

Time-dependent communications or transactions are usually called:

synchronous

38

A software system providing a common software infrastructure and database is called

enterprise resource planning

39

In which of the following ways does technology help to improve service performance?

reducing the need for customers to wait in line

40

The management of projects involves three phases:

1. planning
2. scheduling
3. controlling

41

Define project organization

an organization formed to ensure that programs (prjects) receive the proper management and attentio

42

Which of the following statements regarding Gantt charts is true?

Gantt charts are visual devices that show the duration of activities in a project.

43

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.

44

Slack time equals:

latest start - earliest start

45

The critical path of a network is the:

longest-time path through the network

46

PERT analysis computes the variance of the total project completion time as:

the sum of the variances of all activities on the critical path.

47

The crash cost per period:

1. is the difference in costs divided by the difference in times (crash and normal)
2. is considered to be linear in the range between normal and crash
3. needs to be determined so that the smallest cost values on the critical path can be considered for time reduction first
