Question 1

It is often considered simple to integrate disparate legacy systems of several companies.

Accepted Answer

Integrating disparate legacy systems of several companies is a complex and challenging task that requires careful planning and execution. The systems may have different data structures, programming languages, and platforms, and may not be designed to communicate with each other. In addition, there may be legal and security issues to consider when sharing data across organizational boundaries. Therefore, integrating legacy systems requires technical expertise, collaboration, and patience to overcome these challenges.

Question 2

A small ad hoc team usually performs a quick preliminary investigation to determine the need for a new system.

Accepted Answer

A small ad hoc team is typically formed to conduct a preliminary investigation to determine whether a new system is required. This type of investigation may involve identifying the problems or opportunities that a new system could address, assessing the feasibility of a new system, and establishing the initial requirements for the system.

Question 3

If the return on investment (ROI) of an economic analysis is negative,the system is economically feasible,or cost justified.

Accepted Answer

A negative ROI indicates that the costs of the project outweigh its returns or benefits. Therefore, the system is not economically feasible or cost justified.

Question 4

The systems analysis phase is a three-step process.

Accepted Answer

The systems analysis phase is typically a multi-step process that involves various activities, such as understanding the user needs, defining system requirements, creating system designs, and evaluating alternative solutions.

Question 5

State charts represent highly active states that are triggered by completion of the actions of other states.

Accepted Answer

State charts represent states and transitions in a system, but highly active states are not specifically defined by the completion of actions in other states. Instead, state charts show how states change in response to events.

Question 6

While data flow diagrams are easy to learn and use,they cannot describe a system completely.

Accepted Answer

Data flow diagrams are a graphical representation of a system's flow of data, but they do not capture all the details of the system, such as the physical layout, hardware components, and programming logic. Therefore, they cannot describe a system completely.

Question 7

In Extreme Programming (XP),the initial software is developed over a period of several months with intense research and preparation.

Accepted Answer

In Extreme Programming, the initial software is developed in a short time frame, usually in weeks or even days, through iterations and continuous feedback from the customer. This approach emphasizes rapid delivery of functional software rather than extensive upfront planning and preparation.

Question 8

A data store is any event or sequence of events in which data is either changed or acted on.

Accepted Answer

A data store is a repository for persistently storing and managing collections of data, not an event or sequence of events.

Question 9

Systems integration deals with the analysis and development of a stand-alone information system.

Accepted Answer

Systems integration deals with the combination and coordination of multiple information systems into a cohesive and functional whole, rather than the development of a single stand-alone system.

Question 10

A___________ is a paragraph that communicates the most important overarching goal of the organization for the next few years.
A)mission statement
B)corporate value
C)financial statement
D)scenario plan

Accepted Answer

A mission statement communicates the fundamental purpose and goal of an organization. It typically outlines the organization's values, focus, and objectives. The overarching goal for the next few years is a common component of a mission statement. Corporate values refer to the beliefs and principles that guide the organization's decisions and actions, while a financial statement communicates the organization's financial performance. A scenario plan is a tool for exploring and preparing for potential future events and their impacts.

Question 11

Cut-over conversion reduces risks because it confines any problems to fewer units.

Accepted Answer

Cut-over conversion, also known as direct or big bang conversion, involves switching over from the old system to the new system in one operation. This approach can actually increase risks because it affects all units at once, leaving no room for gradual adjustment or troubleshooting on a smaller scale.

Question 12

Legacy systems are older systems that organizations decide to continue to use because the investment in a new system would not justify the improved features or because the old systems have some advantage that cannot be obtained from newer systems.

Accepted Answer

Legacy systems are commonly kept in use by organizations due to cost or functional reasons, making the statement true.

Question 13

Organizational culture includes issues such as tendency to share or not to share information among units and people,willingness to team-play,and the proclivity of employees to experiment with new ideas and technologies.

Accepted Answer

This statement accurately describes some of the components included in organizational culture.

Question 14

Agile methods treat software development as a series of contacts with users.

Accepted Answer

Agile methods emphasize iterative development and frequent communication with users and stakeholders to gather feedback and refine requirements. This approach helps ensure that the final product meets users' needs and expectations.

Question 15

The systematic approach of the SDLC is recommended if the system is complex and consists of many modules.

Accepted Answer

The phases of the SDLC help ensure that the entire system is carefully designed, tested, and implemented. This is especially important in complex systems with multiple modules to ensure that all components work together seamlessly.

Question 16

When planning,it is important to align IT strategies with the overall strategies of the organization.

Accepted Answer

IT strategies must align with the overall strategies of the organization to ensure that technology is being leveraged to support business objectives and contribute to the overall success of the organization.

Question 17

SDLC stands for systems development life cycle.

Accepted Answer

SDLC or systems development life cycle refers to the process of planning, designing, developing, testing, deploying, and maintaining information systems or software applications.

Question 18

The IT mission includes the ideal combination of hardware,software,and networking to support the corporation.

Accepted Answer

The answer of The IT mission includes the ideal combination...

Question 19

It is difficult,if not impossible,to devise a way to measure software development competence.

Accepted Answer

Unlike other fields where certifications, degrees, and standardized exams can be used to measure competence, software development involves a wide range of skills, experiences, and methodologies that cannot be easily measured. Additionally, what works for one project might not work for another, and a developer's effectiveness may only become apparent over time. Therefore, measuring software development competence is difficult if not impossible.

Question 20

Agile methods make extensive use of iterative programming.

Accepted Answer

Agile methods emphasize on iterative and incremental development, where the software is developed in short cycles called iterations or sprints. This enables the team to receive feedback at regular intervals and make necessary adjustments to the product.
