Question 1

When designing a questionnaire, arrange questions in a random order, intermixing simple and more complex topics.

Accepted Answer

Questions should be arranged in a logical and coherent order, ensuring that respondents can understand the context and meaning of each question. Simple questions should precede more complex ones, and related questions should be grouped together. Randomizing questions can create confusion and reduce the quality of the data collected.

Question 2

_____ enable a systems analyst to identify a problem, evaluate the key elements, and develop a useful solution.​

Accepted Answer

Analytical skills involve breaking down complex problems into smaller components and evaluating them methodically. This is a critical skill for a systems analyst in identifying problems and developing effective solutions. Artistic skills, interpersonal skills, and confrontational skills may be useful in other situations, but they are not as directly relevant to the work of a systems analyst.

Question 3

In a sequence diagram, vertical arrows represent messages from one object to another.

Accepted Answer

horizontal

Question 4

The main objective of a sample is to ensure that it represents the overall population accurately.

Accepted Answer

The main objective of a sample is to accurately represent the overall population, as it is often infeasible or impractical to study an entire population.

Question 5

Before publishing a form on the Internet or a company intranet, a systems analyst should protect it so users can change the layout or design but cannot fill it in.

Accepted Answer

Before publishing a form on the Internet or a company intranet, a systems analyst should protect it so that users can fill it in but cannot change the layout or design.

Question 6

In the rapid application development (RAD) model in the accompanying figure, during the _____ phase, users interact with systems analysts and develop models and prototypes that represent all system processes, outputs, and inputs.

Accepted Answer

In the RAD model, during the user design phase, users interact with systems analysts to develop models and prototypes that represent all system processes, outputs, and inputs. This phase focuses on user experience and involves frequent iterations to improve the design of the system. The other phases of the RAD model are requirements planning, construction, and cutover.

Question 7

The personal interview usually is the least expensive fact-finding technique.

Accepted Answer

most

Question 8

_____ are important to a systems analyst who must work with people at all organizational levels, balance conflicting needs of users, and communicate effectively.

Accepted Answer

Interpersonal skills are crucial for a systems analyst as they need to communicate effectively, collaborate with people at different levels, and manage conflicts while addressing the needs of users. Problem-solving skills may also be important, but they are not exclusive to systems analysts and are required in many other professions. Artistic skills and confrontational skills are not relevant to the role of systems analyst.

Question 9

In the rapid application development (RAD) model in the accompanying figure, the _____ phase focuses on program and application development tasks similar to the SDLC.

Accepted Answer

In the RAD model, the construction phase is where the program and application development tasks are completed, similar to the SDLC's implementation stage. The requirements planning and user design phases in RAD are focused on rapidly prototyping and iterating on the solution based on user feedback. The cutover phase is focused on transitioning the solution into production.

Question 10

A graphic modeling program is used to manage details of a complex project, create queries to retrieve specific information, and generate custom reports.

Accepted Answer

database

Question 11

A single site visit usually gives true pictures, so it is unnecessary to visit more than one installation.

Accepted Answer

Visiting multiple installations can provide a more comprehensive understanding of a particular operation and can help identify patterns and trends. Additionally, there may be variations in equipment, practices, or policies between different installations, which can impact observations and conclusions. Therefore, it is beneficial to visit more than one installation for a robust assessment.

Question 12

Joint application development (JAD) provides a fast-track approach to a full spectrum of system development tasks, including planning, design, construction, and implementation.

Accepted Answer

RAD, Rapid application development, Rapid application development (RAD), RAD (Rapid application development)

Question 13

Rapid application development (RAD) relies heavily on _____.

Accepted Answer

Rapid application development (RAD) relies heavily on prototyping, where developers quickly create and test prototypes of the software to gather feedback and iterate on design changes. Management direction, agile methods, and scrum may also be used in RAD, but prototyping is the key factor.

Question 14

An agile approach emphasizes continuous feedback, and each incremental step is affected by what was learned in the prior steps.

Accepted Answer

An agile approach is characterized by continuous feedback and adaptation based on what is learned in each iteration or increment. This iterative, incremental process is what allows for flexibility and responsiveness to changing requirements or stakeholder needs.

Question 15

In addition to joint application development, another popular user-oriented method is _____, which resembles a condensed version of the entire SDLC with users involved every step of the way.

Accepted Answer

Rapid application development (RAD) involves users in every step of the development process, similar to joint application development. However, RAD is a more condensed version of the SDLC, with an emphasis on prototyping and iterative development. Neither agile method, sampling, nor brainstorming are complete SDLC methodologies with continuous user involvement.

Question 16

In the rapid application development (RAD) model, the _____ phase resembles the final tasks in the SDLC implementation phase.

Accepted Answer

In the RAD model, the cutover phase is the final phase, which is similar to the implementation phase in the SDLC. This phase involves the deployment and transition of the system from the development environment to the production environment, which is the final step in the implementation phase of the SDLC.

Question 17

The ability to manage information is the mark of a successful systems analyst and an important skill for all IT professionals.

Accepted Answer

Managing information is a key aspect of IT and systems analysis, as professionals need to be able to gather, organize, analyze, and communicate data effectively to support business goals and decision-making processes. Without strong information management skills, IT professionals may struggle to provide valuable insights or recommendations based on available data. Therefore, the ability to manage information is an important skill for all IT professionals.

Question 18

The _____ phase of the SDLC includes four main activities: requirements modeling, data and process modeling, object modeling, and consideration of development strategies.

Accepted Answer

The systems analysis phase of the SDLC involves analyzing the current system and determining what needs to be improved or developed. This includes identifying requirements, modeling data and processes, creating object models, and considering possible development strategies. Therefore, option B is the correct choice. The other phases (systems planning, systems design, and systems implementation) occur before and after the systems analysis phase.

Question 19

One of the main activities in the systems analysis phase is _____, which involves fact-finding to describe the current system and identification of the specifications for the new system.

Accepted Answer

The main activity in the systems analysis phase is requirements modeling, which involves fact-finding to describe the current system and identification of the specifications for the new system. Objective modeling, goal-based modeling, and user-based modeling are all types of modeling techniques that can be used during the requirements modeling phase but are not the main activity.

Question 20

Greater user involvement in the system development process usually results in _____.

Accepted Answer

When users are more involved in the system development process, they are more likely to get a system that meets their specific needs and requirements. This results in more satisfied users.
