Question 1

The benefits of reuse grow as more corporate experience is gained from it.

Accepted Answer

The benefits of reuse grow as more corporate experience is gained from it, but so do the costs and the amount of resources necessary for reuse to work well.

Question 2

Research has found that reuse of object class libraries resulted in decreased productivity.

Accepted Answer

Some evidence suggests that reuse can be effective, especially for object classes. For example, one laboratory study found that reuse of object class libraries resulted in increased productivity, reduced defect density, and reduced rework.

Question 3

In many instances, off-the-shelf software can meet up to ________ percent of an organization's needs.

Accepted Answer

C) A reasonable estimate is that off-the-shelf software can at best meet 70 percent of an organization's needs.

Question 4

The provision of computing resources over the Internet so that customers do not need to invest in infrastructure is called:

Accepted Answer

A) Cloud computing refers to the provision of applications over the Internet, where customers do not have to invest in the hardware and software resources needed to run and maintain the applications.

Question 5

All of the following are benefits of enterprise solutions, EXCEPT:

Accepted Answer

D) The purpose of ERP systems is not to change business processes but rather to provide solutions for individual business functions.

Question 6

All of the following are reasons to go with cloud computing EXCEPT:

Accepted Answer

C) There is no guarantee that cloud computing will result in reduced development time. It depends on the application.

Question 7

Rework can be reduced by reusing object class libraries.

Accepted Answer

Some evidence suggests that reuse can be effective, especially for object classes. For example, one laboratory study found that reuse of object class libraries resulted in increased productivity, reduced defect density, and reduced rework.

Question 8

The reuse of object class libraries has been found to reduce defect density.

Accepted Answer

Some evidence suggests that reuse can be effective, especially for object classes. For example, one laboratory study found that reuse of object class libraries resulted in increased productivity, reduced defect density, and reduced rework.

Question 9

A system that integrates individual traditional business functions into a series of modules so that a single transaction occurs seamlessly within a single information system rather than several separate systems best describes:

Accepted Answer

A) Enterprise resource planning systems consist of a series of modules for various business functions.

Question 10

Storage refers to making software assets available for others to use.

Accepted Answer

Storage involves making software assets available for others to use.

Question 11

The practice of turning over responsibility of some or all of an organization's information systems applications and operations to an outside firm is referred to as:

Accepted Answer

C) Outsourcing is defined as the turning over responsibility for IS functions to an outside firm. The only other choice that is even remotely close is time sharing, the idea that one would share resources (such as a mainframe) with another organization.

Question 12

The primary concern about cloud computing is:

Accepted Answer

B) Reliability is a major concern for corporations since the entire application is dependent upon an outside vendor.

Question 13

Due to the low cost of developing a reusable component, most organizations can compete economically with established commercial organizations that focus on selling components as their main line of business.

Accepted Answer

Because of the considerable costs of developing a reusable component, most organizations cannot compete economically with established commercial organizations that focus on selling components as their main line of business.

Question 14

Component-based development's focus is on creating specific pieces of software that can only be used once.

Accepted Answer

Component-based development is similar to object-oriented development in that the focus is on creating general-purpose pieces of software that can be used interchangeably in many different programs.

Question 15

As more corporate experience is gained from reuse, costs and the amount of resources necessary for reuse to work will increase also.

Accepted Answer

The benefits of reuse grow as more corporate experience is gained from it, but so do the costs and the amount of resources necessary for reuse to work well.

Question 16

Because existing pieces of software have already been tested, reusing them tends to result in higher-quality software with lower defect rates, decreasing maintenance costs.

Accepted Answer

This question deals with software reuse. Reusing software increases programmer productivity as well as cuts testing time.

Question 17

When developing information systems, an organization could use all of the following EXCEPT:

Accepted Answer

E) All choices except for E make sense, since, according to the text, all are possible ways to develop software.

Question 18

One type of cloud computing service that allows companies to order server capacity and storage on demand is called:

Accepted Answer

C) Cloud computing includes hardware as a service, the ability for an organization to order server capacity and storage on demand.

Question 19

Strategic business goals of the organization must be matched to the organizations approach to off-the-shelf software.

Accepted Answer

When an organization's management decides to pursue reuse as a strategy, it is important for the organization to match its approach to reuse with its strategic business goals.

Question 20

Packaged software producers create software such as:

Accepted Answer

B) Packaged software is off-the-shelf software.
