Question 1

Throw-away prototyping preserves the prototype that has been developed.

Accepted Answer

Throw-away prototyping is a type of prototyping where the prototype developed is not preserved. It is used to quickly create and test ideas without investing too much time and resources in creating a final product. Once the prototype serves its purpose, it is discarded, and the development team begins work on creating a more refined solution.

Question 2

During JAD,the group interaction process is typically not well supported by computing.

Accepted Answer

During JAD, group interactions involve face-to-face discussions and brainstorming sessions which cannot be fully supported by computing. While some technology such as whiteboards, projectors, and collaboration software can be used to aid the process, the interaction is mainly driven by human communication and collaboration.

Question 3

A first step in any BPR effort is to understand what processes need to change.

Accepted Answer

Before any changes can be made, it is essential to identify the processes that need to be improved, streamlined or eliminated. This requires a thorough understanding of the current processes, their shortcomings, and the desired outcomes. Only then can appropriate changes be made to achieve the desired results.

Question 4

Informal systems develop because of inadequacies of formal procedures,individual work habits and preferences,and resistance to control.

Accepted Answer

Informal systems typically arise due to factors such as these, rather than being intentionally designed or formally established.

Question 5

The primary purpose of using JAD in the analysis phase is to collect systems requirements simultaneously from the key people involved with the system.

Accepted Answer

JAD (Joint Application Development) is a collaborative approach used in the analysis phase to gather requirements from key stakeholders, including users, business analysts, and technical specialists simultaneously. Therefore, the primary purpose of using JAD is to collect systems requirements from key people involved with the system.

Question 6

If you encounter contradictory information about procedures from interviews,questionnaires,or observations,you should reconcile the contradictions before proceeding to other analysis tasks.

Accepted Answer

The answer of If you encounter contradictory information about procedures...

Question 7

In documents you can find information about special information processing circumstances that occur irregularly.

Accepted Answer

Documents can contain information about unusual circumstances or exceptions to regular procedures.

Question 8

When comparing observations and document analysis,the expense of observations is rated moderate.

Accepted Answer

The answer of When comparing observations and document analysis,the expense...

Question 9

As observations are unbiased,they are preferable to other requirements determination techniques.

Accepted Answer

Observations can be biased due to the observer's perspective or interpretation, and they may not capture all necessary requirements compared to other techniques like interviews or surveys.

Question 10

While being observed,employees may follow exact procedures more carefully than they typically do.

Accepted Answer

This phenomenon is known as the Hawthorne effect, where individuals modify their behavior when they are being observed or studied. They may perform better or differently than they typically would in order to meet expectations, which can impact the accuracy of the data or observations gathered.

Question 11

Referencing a JAD session,the sponsor is the individual responsible for organizing and running a JAD session.

Accepted Answer

The facilitator, not the sponsor, is responsible for organizing and running a JAD session. The sponsor typically provides support and resources.

Question 12

When performing observations,it is best to select typical people and sites as opposed to atypical people and sites.

Accepted Answer

The answer of When performing observations,it is best to select...

Question 13

When gathering system requirements,document analysis and observation are used the least.

Accepted Answer

Document analysis and observation are commonly used in gathering system requirements as they provide valuable information that can help identify user needs and system features. Both methods can help identify requirements that may not be apparent through interviews or questionnaires. Therefore, the statement that they are used the least is false.

Question 14

A JAD is an inexpensive,popular requirements determination technique.

Accepted Answer

Joint Application Development (JAD) can be costly due to the need for facilitated workshops, involving multiple stakeholders and resources, although it is popular for its collaborative approach.

Question 15

The goal with using prototyping to support requirements determination is to build the ultimate system from prototyping.

Accepted Answer

The goal of using prototyping to support requirements determination is to gather feedback and refine the requirements, not necessarily to build the ultimate system from the prototype. The ultimate system may be developed later using the refined requirements.

Question 16

As a systems analyst,it is part of your job to create a document for a missing work procedure.

Accepted Answer

The answer of As a systems analyst,it is part of...

Question 17

When comparing observations and document analysis,the chances for follow-up and probing with document analysis are rated high to excellent.

Accepted Answer

Document analysis is a static method that does not allow for follow-up or probing, unlike observations which can be interactive and allow for real-time questioning and clarification.

Question 18

In documents you can find information about the values of the organization or individuals who can help determine priorities for different capabilities desired by different users.

Accepted Answer

Yes, values of the organization or individuals can provide insight into what capabilities are most important to different users and help determine priorities accordingly.

Question 19

The idea behind BPR is to reorganize the complete flow of data in major sections of an organization to eliminate unnecessary steps,achieve synergies among previously separate steps,and become more responsive to future changes.

Accepted Answer

This statement accurately describes the concept of Business Process Reengineering (BPR). BPR involves redesigning and reorganizing an organization's core business processes to improve efficiency, reduce waste, and increase customer satisfaction. The goal is to achieve a fundamental rethinking and radical redesign of business processes to achieve dramatic improvements in critical measures of performance, such as cost, quality, service, and speed.

Question 20

When comparing observations and document analysis,the time required for document analysis is rated as low to moderate.

Accepted Answer

Document analysis is generally considered less time-consuming than making observations, as documents can be reviewed and analyzed at a faster pace than in-person observation. However, the time required for document analysis can vary depending on the number and length of documents that need to be reviewed, the complexity of the information in the documents, and the level of detail required in the analysis. Therefore, it is rated as low to moderate.
