Question 1

Match each of the following SDLC phases with its corresponding definition.
-The phase of the SDLC in which the current system is studied and alternative replacement systems are proposed

Accepted Answer

The Systems Analysis phase involves studying the current system and proposing alternative systems for replacement.

Question 2

Which of the following is NOT an approach to systems development?

Accepted Answer

Prototyping, joint application design, agile methodologies, and rapid application development are all approaches to systems development. Reengineering analysis is not considered an approach to systems development; rather, it is a method for analyzing and redesigning existing business processes.

Question 3

Current approaches to systems development that focus on adaptive methodologies, people instead of roles, and an overall self-adaptive development process best defines:

Accepted Answer

The given approaches of focusing on adaptive methodologies, people instead of roles, and an overall self-adaptive development process are the core principles of Agile Methodologies. Participatory Design, Rapid Application Development, Joint Application Design, and CASE do not fully address these principles.

Question 4

In which SDLC phase is the information system coded, tested, and installed in the organization?

Accepted Answer

The implementation and operation phase is where the system is actually built and installed in the organization. This includes coding, testing, and deployment of the information system.

Question 5

Management skills:

Accepted Answer

C) Management skills are most helpful when managing projects, resources and risks.

Question 6

A centralized database that contains all diagrams, forms and report definitions, data structure, data definitions, process flows and logic, and definitions of other organizational and system components best describes:

Accepted Answer

A repository is a centralized database that contains all the information about the diagrams, forms, report definitions, data structure, data definitions, process flows and logic, and definitions of other organizational and system components. It provides a single source of truth for the various components and ensures consistency and accuracy across the organization.

Question 7

Match each of the following SDLC phases with its corresponding definition.
-The phase of the SDLC in which the system chosen for development in systems analysis is first described independently of any computer platform and is then transformed into technology-specific details from which all programming and system construction can be accomplished

Accepted Answer

Systems Design is the phase of the SDLC that involves transforming the system identified during systems analysis into a technology-specific design from which all programming and system construction can be accomplished.

Question 8

Analytical skills:

Accepted Answer

D) Analytical skills are most useful for the systems analyst in terms of understanding a project and how it fits into an organization.

Question 9

Interpersonal skills:

Accepted Answer

A) Of all the choices above, the logical one is the first one since interpersonal skills are most beneficial for working with all constituencies.

Question 10

Which of the following allows hardware and software from different vendors to work together in an application?

Accepted Answer

Systems integration is the process of connecting hardware and software from different vendors to work together in an application. Systems coupling is the degree to which software components depend on each other, systems decomposition involves breaking down a complex system into smaller, more manageable parts, participatory design involves involving end-users in the design process, and joint application design involves bringing together stakeholders to design a new system or application.

Question 11

The need for a new or enhanced system is identified during:

Accepted Answer

The need for a new or enhanced system is generally identified during the systems planning and selection phase, as this is the first stage in the systems development life cycle where the organization assesses its current systems and identifies areas for improvement or new systems that may be needed to address business needs or opportunities. The other phases of the SDLC (systems analysis, design, coding, implementation and operation) involve further development and implementation of the new or enhanced system to meet the identified need.

Question 12

A systems development approach that originated in northern Europe, in which users and the improvement of their work lives are the central focus, best defines:

Accepted Answer

The description of the systems development approach as centering around users and the improvement of their work lives is a key characteristic of Participatory Design (PD), which originated in northern Europe. Rapid application development, joint application design, CASE, and Agile Methodologies may also involve user input, but do not prioritize the improvement of user work lives as explicitly as PD.

Question 13

The three key principles shared by the Agile Methodologies include:

Accepted Answer

The Agile Methodologies share a focus on self-adaptive processes, which is the ability to adapt and respond to changes throughout the project. This is achieved through continuous feedback and iteration, as well as collaboration and communication within the project team. The other options, a focus on predictive methodologies and a focus on roles, are not principles shared by Agile Methodologies.

Question 14

In which phase will the systems analyst convert the description of the recommended alternative solution into logical and then physical system specifications?

Accepted Answer

The phase where the systems analyst converts the description of the recommended alternative solution into logical and then physical system specifications is the systems design phase.

Question 15

A systems development methodology created to radically decrease the time needed to design and implement information systems best describes:

Accepted Answer

The description provided matches the characteristics of Rapid Application Development (RAD) methodology which emphasizes on short development cycles and focuses on user involvement in the design process.

Question 16

Building a scaled-down version of the desired system best describes:

Accepted Answer

Prototyping involves building a scaled-down version of the system in order to quickly test and evaluate its functionality and design. This approach allows for quicker and more efficient development and can help identify any issues or improvements early on in the process.

Question 17

A description of the alternative solution recommended by the analysis team is provided during the:

Accepted Answer

C) During the analysis phase any alternative solutions are recommended and included in analysis documents.

Question 18

Priorities for systems and projects are deliverables for the:

Accepted Answer

Priorities for systems and projects are typically determined during the systems planning and selection phase, where the organization evaluates different options and decides which system or project to pursue based on factors such as cost, feasibility, and strategic alignment. This decision then influences the direction of subsequent phases such as systems analysis and design. Therefore, A is the best answer.

Question 19

In which SDLC phase will the analyst study the organization's current procedures and the information systems used to perform tasks?

Accepted Answer

The analyst will study the current procedures and information systems used to perform tasks in the Systems Analysis phase of the SDLC. This is important so that the analyst can identify any inefficiencies or areas for improvement in the current system and determine the requirements for the new system.

Question 20

Technical skills:

Accepted Answer

Technical skills help individuals understand the potential and limitations of information technology, which is critical in making informed decisions about its application in organizations. The other choices (A, C, D, and E) are important skills needed by information systems professionals, but do not relate specifically to technical skills.
