Question 1

Which of the following statements is true of the composition of a development team over the different phases of the systems development life cycle?

Accepted Answer

During integrated testing and conversion, the team will be augmented with business users to ensure that the system operates correctly in its actual business environment. In other stages, such as requirements definition or design and implementation, the team may not need as many business users.

Question 2

Which is the most important phase in the systems development process?

Accepted Answer

Determining the system's requirements is crucial as it lays the foundation for the entire development process, ensuring that the system meets the needs of users and stakeholders.

Question 3

The ________ approach is the classical process used to develop information systems.

Accepted Answer

The systems development life cycle (SDLC) is the traditional and classical process used in the development of information systems. It involves a series of phases that must be completed in order to design, develop, and implement an effective information system. RAD, OOD, and XP are all alternative development approaches that focus on faster and more iterative processes compared to SDLC.

Question 4

When compared to program development,systems development is ________.

Accepted Answer

Systems development is broader in scope than program development. While program development focuses on developing a single software program or application, systems development involves the development of entire systems that may include multiple programs, hardware components, and other elements that work together to achieve specific goals or objectives. Systems development may also involve a range of different technical and non-technical tasks, including requirements analysis, design, testing, implementation, and ongoing maintenance and support.

Question 5

The primary purpose of the requirements analysis phase is to ________.

Accepted Answer

The requirements analysis phase is focused on identifying and documenting the specific features and functions that the new system must have to meet the needs of its users. This stage helps ensure that the project team has a clear understanding of project requirements before development begins.

Question 6

Developers in the ________ phase of the systems development life cycle use management's statement of the system needs in order to begin developing a new information system.

Accepted Answer

In the system definition phase, developers use management's statement of system needs to outline the scope and purpose of the new information system, setting the foundation for further development stages.

Question 7

Which of the following is a typical concern for developers while using prototypes?

Accepted Answer

The answer of Which of the following is a typical...

Question 8

Which of the following is the first phase of the systems development life cycle process?

Accepted Answer

The first phase of the systems development life cycle process is the system definition phase. In this phase, the objectives and scope of the project are established, and the feasibility of the project is determined. It is followed by the requirements analysis phase, where the specific needs and requirements of the proposed system are identified.

Question 9

Which of the following is true with regards to bigger and longer projects?

Accepted Answer

As projects become bigger and longer, the changes in requirements are more likely to increase. This is because the longer a project runs, the more time stakeholders have to change their mind, introduce new requirements, or alter existing ones. Therefore, keeping track of requirements becomes more complex in longer projects. Diseconomies of scale can also become more significant as a project grows, with costs and time increasing as the project gets larger. Average contribution per worker may or may not increase depending on the complexity of the project, and project budgeting and scheduling can become more complex, not easier.

Question 10

According to Brooks' Law,which of the following is a likely consequence of adding more people to late projects?

Accepted Answer

Brooks' Law states that adding more people to a late project will actually delay it further due to the time it takes to train and integrate the new team members. This means that the costs of training new people can overwhelm the benefits of their contribution, therefore choice B is the most likely consequence.

Question 11

Which of the following steps in the systems definition process aims to eliminate obviously nonsensible projects?

Accepted Answer

Assessing project feasibility includes evaluating whether the project is practical, economic, and technically feasible. This step helps to eliminate unviable projects. Defining the system goals and scope establishes the objectives and boundaries of the system. Forming the project team involves selecting individuals with the requisite skills and knowledge to execute the project. Planning the project involves developing a detailed roadmap for the system development project. None of these steps specifically aim to eliminate nonsensible projects.

Question 12

________ feasibility concerns whether the new information system fits within a company's customs,culture,charter,or legal requirements.

Accepted Answer

Organizational feasibility concerns whether the new information system is compatible with the organization's customs, culture, charter, or legal requirements. It assesses whether the organization has the necessary resources and capabilities to implement and maintain the new system. Technical feasibility concerns whether the system can be developed and implemented using existing technology and infrastructure. Cost feasibility concerns whether the system can be developed within a specified budget. Schedule feasibility concerns whether the system can be developed and implemented within a specified timeframe.

Question 13

The first step in defining a new information system is to ________.

Accepted Answer

Defining the goals and scope of the project is the first step in the systems development life cycle (SDLC). This helps to establish the purpose of the system and what it is meant to achieve before moving onto assessing feasibility, determining the schedule and budget, and forming the project team.

Question 14

During the requirements analysis phase of the systems development life cycle,the development team will create a(n)________ if the new system involves a new database or substantial changes to an existing database.

Accepted Answer

During the requirements analysis phase, if the new system involves a new database or substantial changes to an existing database, the development team will create a data model. A data model represents the organization of data and its relationships in a conceptual way, and it helps to ensure that the system's data is accurate, complete, and consistent.

Question 15

During requirements definition,a development team's composition would be typically heavy with ________.

Accepted Answer

During requirements definition, the development team would typically require more systems analysts to analyze and document the requirements, create process flows, wireframes, and use cases. While programmers are important for development, they come into play after the requirements have been defined. Business users may provide input but are not typically a part of the development team, and beta testers come into play later in the development cycle.

Question 16

In which of the following phases of the systems development life cycle do developers identify the particular features and functions of a new system?

Accepted Answer

In the requirements analysis phase, developers identify the particular features and functions of a new system by analyzing and gathering information about the system's requirements from users and stakeholders. This phase helps to define the scope of the project and lays the foundation for the design and development phases. The other phases focus on defining the system, designing its components, and implementing the system.

Question 17

According to Brooks' Law,adding more people to a late project ________.

Accepted Answer

Brooks' Law states that adding more people to a late project will make the project later. This is due to the fact that communication and coordination among the increasing number of team members leads to inefficiencies and increased overhead, thereby slowing down the project further.

Question 18

Which of the following is true of information systems?

Accepted Answer

Information systems can be adapted or customized to fit the specific needs of a business. Off-the-shelf software may be used as a starting point, but it can be modified to meet the requirements of the organization. Therefore, option B is the correct answer. Options A, C, and D are incorrect because they state that information systems cannot be adapted, purchased as off-the-shelf software or tailor-made respectively, which is not true.

Question 19

The process of creating and maintaining information systems is called ________.

Accepted Answer

The term "systems development" refers to the entire process of creating, designing, implementing, and maintaining information systems. This process includes tasks such as defining system requirements, designing system architecture, developing and testing software, and training end-users.
