Technical feasibility refers to the likelihood that existing technology will be able to meet the needs of the system.

Question 20

Systems analysis and design is the process of creating and maintaining information systems.

Question 21

The easiest and cheapest time to alter the information system is in the component design phase.

Question 23

Beta testing is the first stage of testing.

Question 24

With plunge installation,the organization shuts off the old system and starts the new system.

Question 25

Developers can reduce the labor cost of testing by writing programs that invoke system features automatically.

Question 26

The data model is constructed on the basis of user interviews and must be validated by those users.

Question 27

Question 34

Beta testing is the process of allowing future system users to try out the new system on their own.

Question 35

Creating the database and testing the data occurs in the maintenance phase of the SDLC.

Question 36

Question 39

With pilot installation,the organization implements the entire system across the entire business.

Question 40

Existing systems are the only source to determine requirements.

Question 41

Diseconomies of scale is the process by which users agree to one set of requirements,then add a bit more,then add a bit more,until,over time,they have described a completely new project.

Question 42

Patches typically involve fixes to hundreds or thousands of problems.

Question 43

Projects that spend too little time documenting requirements are sometimes said to be in analysis paralysis.

Question 44

Configuration control refers to a set of management policies,practices,and tools that developers use to maintain control over the project's resources.

Question 45

You can trade off project requirements against both time and cost.

Question 46

The initial WBS plan is denoted as the baseline WBS.

Question 47

One of the ways in which companies address the difficulties of scheduling a large-scale project is to avoid the major schedule risks and never develop software in-house.

Question 48

Small scale projects seldom have professional IT support.

Question 49

A Gantt chart is a hierarchy of the tasks required to complete a project.

Question 50

Each task in a project should culminate in one or more results or deliverables.

Question 51

Small scale projects usually involve experienced personnel who can work independently with minimal supervision.

Question 52

In an SDLC,adding more people creates diseconomies of scale.

Question 53

A function point is the sequence of activities that determines the earliest date by which the project can be completed.

Question 54

The maintenance phase usually starts another cycle of the SDLC process.

Question 55

Large scale projects tend to be informal and loose.

Question 56

Any task not on the critical path can run late without ever delaying the project.

Question 57

A baseline shows the final time and cost budget for a project.

Question 58

One of the problems of the waterfall nature of the SDLC is that the team needs to do more requirements work,even after a phase is supposedly finished.

Question 59

Vendors bundle fixes of low-priority problems into large groups called service packs.

Question 60

One of the trade-offs of project management is to take resources from tasks not on the critical path and assign them to tasks on the critical path.
