Question 1

The sequential development approach has lost favor with most system developers..

Accepted Answer

The sequential development approach, often referred to as the Waterfall model, has lost favor because it is inflexible and does not accommodate changes well, unlike more iterative and agile methodologies that allow for continuous feedback and adaptation.

Question 2

Timeboxing is the imposition of a nonextendable period of time, usually 6 to 9 days.

Accepted Answer

Timeboxing is the practice of setting a fixed, nonextendable period of time for an activity, but it is not limited to 6 to 9 days; it can be any duration depending on the context and needs.

Question 3

Data modeling is a process-centered technique popularized .by the structured analysis and design methodology.

Accepted Answer

The answer of Data modeling is a process-centered technique popularized...

Question 4

Time-boxing fits with the iterative approach.

Accepted Answer

Time-boxing is a technique used in iterative approaches to limit the time spent on a task or iteration, ensuring regular progress and review.

Question 5

An advantage of the model-driven approach is that it makes it easier to identify, conceptualize, and analyze alternative technical solutions.

Accepted Answer

The model-driven approach uses abstract models to represent systems, which helps in visualizing and exploring different technical solutions and their implications.

Question 6

Object-oriented analysis and design attempts to merge the data and process concerns into singular constructs called objects. A system is documented in terms of its objects and their interactions.

Accepted Answer

Object-oriented analysis and design focuses on encapsulating data and behavior into objects, which represent real-world entities and their interactions within a system.

Question 7

Object-oriented analysis and design is an object-centered, data-sensitive technique used to model business requirements in terms of objects and entities using entity relationship diagrams to prototype an information system.

Accepted Answer

Object-oriented analysis and design (OOAD) focuses on modeling systems using objects and classes, not entity relationship diagrams, which are used in relational database design. OOAD uses UML diagrams like class diagrams to represent the system.

Question 8

Commercial off-the-shelf software is a software package or solution that is purchased to support one or more business functions and information systems.

Accepted Answer

Commercial off-the-shelf (COTS) software refers to ready-made software solutions that are available for purchase to fulfill specific business needs, rather than being custom-developed for a particular organization.

Question 9

An enterprise resource planning (ERP) software product is a fully integrated collection of information systems that span most basic business functions required by a major corporation.

Accepted Answer

ERP software integrates various business processes and functions into a single system to streamline operations and information across an organization.

Question 10

When using a COTS solution a gap analysis is often performed.

Accepted Answer

A gap analysis is performed to identify the differences between the capabilities of the COTS solution and the specific needs of the organization, ensuring the solution meets the required objectives.

Question 11

Computer aided systems engineering (CASE) tools are software programs that automate or support the drawing and analysis of system models and provide for the translation of system models into application programs.

Accepted Answer

CASE tools are designed to assist in the software development process by automating tasks such as drawing system models, analyzing them, and translating these models into code, thus enhancing productivity and accuracy.

Question 12

Forward engineering allows a CASE tool to read existing program code and transform that code into a representative system model that can be edited and refined by the systems analyst.

Accepted Answer

Forward engineering involves creating code from a model, not the other way around. Transforming code into a model is reverse engineering.

Question 13

Reverse engineering requires the systems analyst to draw system models, either from scratch or from templates. The resulting models are subsequently transformed into program code.

Accepted Answer

Reverse engineering involves analyzing existing systems to identify their components and interrelationships, often to recreate or understand the system, not to create new models or program code from scratch.

Question 14

Which of the following is NOT one of the principles of Systems Development?
A) Use a problem-solving approach
B) Divide and conquer
C) Establish phases and activities
D) Establish standards for consistent development and documentation
E) Leave the users alone until you have a product they can use.

Accepted Answer

Leaving users alone until a product is ready contradicts the principles of systems development, which emphasize user involvement and feedback throughout the process.

Question 15

RAD stands for:
A) Readily available deliveries
B) Rapid Application Data
C) Rapid Application Development
D) Real Analogy Data
E) None of these

Accepted Answer

RAD stands for Rapid Application Development, which is a software development methodology that focuses on quick development and iteration of prototypes.

Question 16

Which one is NOT an ongoing activity of systems support?
A) Assisting users
B) Continuing analysis of the system
C) Recovering the system
D) Fixing software bugs
E) Adapting the system to new requirements

Accepted Answer

The answer of Which one is NOT an ongoing activity...

Question 17

Which one is NOT one of the common facilities of CASE tools?
A) diagramming tools
B) dictionary tools
C) quality management tools
D) application development environment (ADE) tools
E) testing tools

Accepted Answer

Application development environment (ADE) tools are not typically considered a common facility of CASE tools, which focus more on diagramming, dictionary, quality management, and testing tools.

Question 18

The definition of feasibility is:
A) An ongoing activity by which an analyst plans an acceptable system
B) Measure of how beneficial the development of an information system would be to an organization
C) An activity of measuring and analyzing developer productivity
D) An activity of approximating the time, effort, costs, and benefits of developing systems.
E) None of these

Accepted Answer

Feasibility refers to the measure of how beneficial or practical the development of an information system would be to an organization, assessing its potential success and value.

Question 19

The first CMM level at which consistent project management is practiced is:
A) Level 1
B) Level 2
C) Level 3
D) Level 4
E) Level 5

Accepted Answer

The answer of The first CMM level at which consistent...

Question 20

Which of the following accurately identifies the categories of problems represented by the PIECES framework?
A) Performance, information, economics, control, efficiency, and service
B) Performance, information, economics, cost, efficiency and security
C) Performance, information, efficiency, costs, effectiveness, and services
D) Performance, information, economy, control, efficiency, and security
E) People, information, economy, costs, efficiency, and service

Accepted Answer

The PIECES framework stands for Performance, Information, Economics, Control, Efficiency, and Service, which are categories used to identify problems in information systems.
