Question 1

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

Accepted Answer

Agile methodologies prioritize customer satisfaction by continuously involving users in the development process and incorporating their feedback. This approach helps ensure that the software being developed meets the needs and expectations of its intended users.

Question 2

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 3

While DFDs are easy to learn and use,they have shortcomings-like any diagramming method-and cannot describe a system completely.

Accepted Answer

DFDs only depict the flow of data and processes within a system and do not include details such as timing, data storage structures, and complex decision-making processes. Therefore, they have limitations and cannot describe a system completely.

Question 4

By some estimates more than ninety percent of all BI projects are never completed or fail to deliver all the expected features and benefits.

Accepted Answer

The answer of By some estimates more than ninety percent...

Question 5

SDLC stands for systems development life cycle.

Accepted Answer

SDLC stands for systems development life cycle.

Question 6

The IS mission includes the ideal combination of hardware,software,and networking to support the overarching vision.

Accepted Answer

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

Question 7

Excellent Programming (EXP)includes the following principle: produce the initial software within weeks (rather than months)to receive rapid feedback from users.

Accepted Answer

The answer of Excellent Programming (EXP)includes the following principle: produce...

Question 8

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

Accepted Answer

Software development competence involves a wide range of skills and knowledge, including programming languages, development methodologies, problem-solving ability, communication skills, and more. There is no standardized way to measure all of these factors, making it difficult to create a comprehensive measurement of software development competence. While certain metrics can be used to evaluate specific aspects of software development, such as code quality or productivity, they do not provide a complete picture of an individual's overall competence.

Question 9

In recent years,a growing number of corporations have implemented enterprise ISs such as ERP systems,____ and CRM systems,or other systems that serve the entire organization or many of its units.
A) SCM
B) CAD
C) CAM
D) CMS

Accepted Answer

Enterprise ISs such as ERP systems, SCM, and CRM systems serve the entire organization or many of its units. CAD and CAM systems are typically used by specific departments or units within an organization, while CMS systems are used primarily for managing website content. Therefore, the best choice is A) SCM, as it is often included in enterprise ISs and serves the entire organization.

Question 10

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 11

XP is by far the most documented and best known of agile methods.

Accepted Answer

XP, or Extreme Programming, has been around since the late 1990s and has been extensively documented and studied. It is considered one of the most well-known and widely used agile methods.

Question 12

Physical diagrams represent highly active states that are triggered by completion of the actions of other states; therefore,they focus on internal processing.

Accepted Answer

Physical diagrams, such as state diagrams, represent the states of a system and the transitions between them, focusing on external events and conditions rather than internal processing.

Question 13

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

Accepted Answer

The SDLC approach is recommended for systems that are complex and consist of many modules as it ensures that the development process is organized and follows a logical sequence of steps that lead to the successful completion of the project.

Question 14

If the ROI is negative,the system is economically feasible,or cost justified.

Accepted Answer

If the ROI (return on investment) is negative, it means that the investment has not generated enough profit to cover its initial cost, making it economically unfeasible or not cost justified. Therefore, the statement is false.

Question 15

A data store is any event or sequence of events in which data are either changed or acted on,such as the processing of data into information or the application of data to decision making.

Accepted Answer

A data store is a repository for storing data, not an event or sequence of events. It is where data is kept for future use or retrieval.

Question 16

Legal 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

The term "legacy systems" refers to older systems that organizations continue to use for reasons such as cost of replacement or unique advantages, not "legal systems."

Question 17

Systems modeling looks at the information needs of an entire organization,or at least of a major division of it.

Accepted Answer

The answer of Systems modeling looks at the information needs...

Question 18

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 is true. Organizational culture encompasses various aspects such as communication patterns, teamwork, and innovation values.

Question 19

Usually,members of the original ad hoc team are included in an augmented analysis team to conduct feasibility studies.

Accepted Answer

This statement is true as the original ad hoc team has already worked on the initial analysis and their expertise and experience can be utilized in the feasibility study as well.

Question 20

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

Accepted Answer

This ensures that the IS strategies are supporting the overall goals and objectives of the organization, and can help to prioritize technology investments and initiatives. Failure to align IS strategies can result in wasted resources and a lack of cohesion between business and technology strategies.
