Question 1

The description of fixes and new requirements is the input to a system maintenance phase of a systems development life cycle.

Accepted Answer

The system maintenance phase of a systems development life cycle involves updating and maintaining existing systems. The input to this phase includes descriptions of fixes and new requirements which guide the maintenance process.

Question 2

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

Accepted Answer

Assessing the project feasibility aims to determine whether a project is financially, technically, and operationally feasible. This includes determining if a project is achievable and practical, and whether it aligns with the organization's objectives. Eliminating obviously nonsensible projects would fall under this step. The other steps do not specifically address the elimination of nonsensible projects.

Question 3

The third phase of the systems development life cycle is the component design phase.

Accepted Answer

The component design phase is indeed the third phase of the systems development life cycle. This phase involves breaking down the system into smaller components and designing the specific details for each component.

Question 4

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

Accepted Answer

Organisational feasibility concerns the alignment of the new information system with the company's internal structure, culture, and legal requirements. It aims to ensure that the system will be accepted and adopted by employees and other stakeholders. Schedule feasibility relates to the project timeline, technical feasibility concerns the infrastructure and resources required, and cost feasibility pertains to the financial resources needed to implement the system.

Question 5

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 requirements analysis, if the new system involves a new database or substantial changes to an existing database, the development team will create a data model, which is a visual representation of the data's structure and relationships within the system. A test plan is a document outlining the testing process, while an archetype is a generic model or template that can be used to create similar systems. A prototype is an early version of the system used to gather feedback and make improvements. However, none of these options specifically relate to database design and modeling like a data model does.

Question 6

Explain the tasks performed during the system definition phase of the systems development life cycle.

Accepted Answer

The answer of Explain the tasks performed during the system...

Question 7

Who are the members of a systems project team? Explain the roles of business analysts and systems analysts.

Accepted Answer

The answer of Who are the members of a systems...

Question 8

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 phases, the team will be augmented with business users because they will help in testing and training. During requirements definition, the team will be heavy with business analysts who will gather requirements, and during design and implementation, the team will be heavy with developers, designers and architects who will work on designing and developing the system. During conversion, the team will be heavy with project managers and technical specialists who will oversee the conversion process. Therefore, option A is the correct answer.

Question 9

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

Accepted Answer

Defining the goals and scope of the project is typically the first step in defining a new information system. This helps to ensure that the system will meet the needs of the organization and its stakeholders. Forming the project team, assessing feasibility, and determining schedule and budget usually follow this initial step.

Question 10

Business analysts integrate the work of the programmers,testers,and users.

Accepted Answer

The answer of Business analysts integrate the work of the...

Question 11

A development team's composition changes over time.

Accepted Answer

As projects progress, developers may join or leave the team, and the roles and responsibilities of team members may shift or expand. This can cause the team's composition to change over time.

Question 12

Define the terms technical feasibility and organisational feasibility.

Accepted Answer

The answer of Define the terms technical feasibility and organisational...

Question 13

What are the five phases of the systems development life cycle (SDLC)?

Accepted Answer

The answer of What are the five phases of the...

Question 14

Organisational feasibility refers to estimating the time it will take to complete a project.

Accepted Answer

Organisational feasibility refers to assessing whether a project fits within the overall goals, strategy, and resources of an organization. It does not specifically relate to estimating time.

Question 15

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

Accepted Answer

Determining the system's requirements is the most important phase in the systems development process because it sets the foundation for the entire project. Without a clear understanding of what the system needs to do and how it should function, the project can easily become derailed or fail to meet the business needs. Once requirements are defined, the other phases can build upon that foundation to create a successful information system.

Question 16

The cost feasibility of a systems development project depends on the scope of the project.

Accepted Answer

The scope of the project directly influences the cost feasibility of a systems development project. The larger the scope, the higher the cost of the project will be.

Question 17

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

Accepted Answer

During requirements definition, a development team's composition should be heavy with systems analysts who are responsible for analyzing user needs, documenting requirements, and translating those requirements into functional specifications for the development team. Programmers may not be involved as heavily in this phase, and beta testers and business users may only get involved later in the development process.

Question 18

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

During the requirement analysis phase, developers identify the particular features and functions of a new system by interacting with stakeholders to understand their needs and requirements. This phase is crucial as it sets the foundation for the entire development process.

Question 19

The goals and scope of a new information system are determined during the requirements analysis phase of the systems development life cycle.

Accepted Answer

The answer of The goals and scope of a new...

Question 20

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

Accepted Answer

The requirements analysis phase is focused on determining and documenting the specific features and functions of the new system. This involves understanding the goals and objectives of the project, as well as gathering information from stakeholders and users to identify their needs and requirements. The other options listed may also be important considerations, but they are not the primary purpose of the requirements analysis phase.
