Question 1

Which prototyping step is not the responsibility of the system builders?
A) develop initial prototype
B) use prototype and note desired changes
C) revise and enhance prototype
D) assist with converting the prototype to an operational system

Accepted Answer

The responsibility of using the prototype and noting desired changes typically falls to the users or stakeholders, not the system builders. The system builders focus on developing, revising, and enhancing the prototype, as well as assisting in its conversion to an operational system.

Question 2

Which of the following best describes a common prototyping goal when it is used as part of a prototyping/piloting approach?
A) to establish and demonstrate basic concepts of the new system and to get buy-in from key stakeholders
B) to demonstrate the technical feasibility of the new system
C) to test a complex system
D) both A and B

Accepted Answer

A common prototyping goal when used as part of a prototyping/piloting approach is to establish and demonstrate basic concepts of the new system and to get buy-in from key stakeholders (option A). However, it is also important to demonstrate the technical feasibility of the new system (option B). Therefore, option D is the best choice as it includes both A and B. Option C is not specific enough and may not always be a goal of prototyping.

Question 3

The SDLC phase that typically requires the greatest percentage of the total cost for a custom development project is the ________ phase.
A) definition
B) construction
C) implementation
D) final

Accepted Answer

The construction phase, also known as development, involves actually building and coding the software. This phase typically requires the most resources (including time, money, and personnel) as it involves turning the requirements and design into a functional product.

Question 4

Who usually takes primary responsibility for establishing the custom development costs for an SDLC project?
A) end user
B) business manager
C) IS analyst
D) both B and C

Accepted Answer

Question 5

When prototyping is incorporated into a traditional SDLC approach,it is most commonly included as part of which of the following steps?
A) requirements definition
B) feasibility analysis
C) system design
D) system building

Accepted Answer

Prototyping is commonly used during the requirements definition stage to help stakeholders better understand and visualize the system being developed. By creating a prototype, developers can receive feedback on the functionality and design of the system, which can inform and refine the requirements definition. Integrating prototyping into this stage can also help to identify potential issues or misunderstandings early on, before development has progressed too far.

Question 6

The percentage of resources devoted to the maintenance of a system:
A) generally increases over time.
B) generally decreases over time.
C) generally stays about the same over time.
D) is variable depending on the system.

Accepted Answer

Generally, as a system ages, the maintenance and upkeep required to keep it functioning properly will increase. This is often due to wear and tear, changes in technology or user needs, and other factors that can impact the system's performance. While some maintenance activities may be able to extend the life of the system or prevent major problems, there will still be a long-term trend towards increased resource dedication to keep it operational.

Question 7

Which of the following is a technique where a team of users and IS specialists engage in an intensive session to minimize the total time required for gathering information from multiple participants?
A) RAD
B) Piloting
C) JAD
D) CASE

Accepted Answer

JAD (Joint Application Development) is a technique where users and IS specialists engage in an intensive session to minimize the total time required for gathering information from multiple participants. RAD (Rapid Application Development) focuses more on rapid prototyping and iterative development, while CASE (Computer-Aided Software Engineering) refers to software tools and methods to support software development. Piloting is a technique where a limited version of the system is tested in a real-time or simulated environment.

Question 8

Which of the following is not typically the responsibility of an IT project manager?
A) approve funds for the project
B) oversee multiple project phases
C) determine how long each development task will take
D) form a project team with appropriate knowledge and skills

Accepted Answer

While an IT project manager may provide input on budgeting, it is typically not their sole responsibility to approve funds for the project. This is usually the responsibility of higher-level management or a finance department.

Question 9

Deciding what hardware and systems software will be used to operate the system and defining the processing modules that will comprise the system are part of which SDLC step?
A) system building
B) requirements definition
C) system design
D) feasibility analysis

Accepted Answer

The step in the SDLC that involves deciding what hardware and systems software will be used and defining the processing modules that will comprise the system is system design. This step involves creating a detailed plan for the development of the system and determining the technical specifications required for its implementation. The requirements definition step comes before system design and involves gathering and analyzing user needs and defining the scope of the system. Feasibility analysis is the initial step in the SDLC and involves determining whether a proposed system is practical and viable. System building is the implementation phase of the SDLC where the system is constructed, tested, and installed.

Question 10

Testing a new custom system before implementation is the responsibility of:
A) both users and IS analysts.
B) users only.
C) IS analysts only.
D) independent third parties.

Accepted Answer

Testing a new custom system before implementation involves both the users and IS analysts as they need to work collaboratively to ensure that the system meets the requirements and needs of the users. The IS analysts are responsible for developing and testing the system while the users are responsible for providing feedback and testing the system to ensure that it meets their needs. Additionally, involving independent third parties can provide an objective perspective and further ensure that the system is fully tested and ready for implementation.

Question 11

Which of the following is typical for a pure prototyping approach?
A) Firms use the approach to explore the use of newer technologies.
B) Documentation is less complete than with traditional systems development approaches.
C) Less security and control features are incorporated than with traditional SDLC approach.
D) all of the above

Accepted Answer

A pure prototyping approach typically involves exploring newer technologies, and has less complete documentation and less security and control features than traditional SDLC approaches. All of the options presented are typical characteristics of a pure prototyping approach.

Question 12

Which of the following is not an advantage of prototyping?
A) Only basic system requirements are needed at the front-end of the project.
B) End-prototype typically has more security and control features than a system developed with an SDLC process.
C) Strong top-down commitment may be less necessary at the outset of the project.
D) User acceptance is likely to be higher than with a system developed using an SDLC process.

Accepted Answer

This statement is not true. Prototyping is not necessarily more secure than a system developed using an SDLC process. In fact, since prototyping is often used to quickly create a working model of a system, security features may be overlooked or not given enough attention.

Question 13

Which of the following best describes a responsibility of a systems analyst?
A) ensure the promised benefits of a system are achieved
B) develop detailed system requirements
C) train users
D) all of the above

Accepted Answer

Question 14

A conversion strategy whereby an organization continues to operate the old system together with the new one for one or more cycles,until the new system is working properly and the old system can be discontinued,is called a:
A) pilot strategy.
B) phased strategy.
C) cutover strategy.
D) parallel strategy.

Accepted Answer

A parallel strategy involves running the old and new systems alongside each other for a period of time until it can be ensured that the new system is working effectively before discontinuing the old system. This approach allows for a controlled transition and reduces the risk of disrupting business processes.

Question 15

The ________ approach to systems development has often been referred to as the "waterfall" model.
A) SDLC
B) prototyping
C) RAD
D) XP

Accepted Answer

The term "waterfall" model is often used to describe the traditional or sequential approach to systems development, which is part of the SDLC (Systems Development Life Cycle) methodology. This approach entails completing each stage of the development cycle (planning, analysis, design, implementation, and maintenance) before moving on to the next one.

Question 16

Which of the following accurately describes the order in which a system is tested?
A) module testing, subsystem testing, integration testing, acceptance testing
B) subsystem testing, acceptance testing, integration testing, module testing
C) acceptance testing, integration testing, subsystem testing, module testing
D) module testing, integration testing, subsystem testing, acceptance testing

Accepted Answer

The correct order of testing is module testing, then subsystem testing, integration testing, and finally acceptance testing. This ensures that each individual component (module) works correctly, then they are tested together in subsystems, then integrated into the larger system and tested as a whole, before finally being tested by the user in acceptance testing.

Question 17

The following diagram depicts a cutover conversion strategy.Which of the following best characterizes this type of conversion strategies? 
A) costly
B) time consuming
C) risky
D) all of the above

Question 18

During the feasibility analysis phase of the SDLC,which of the following types of feasibility is not assessed?
A) economic
B) operational
C) time-driven
D) technical

Accepted Answer

Time-driven feasibility is not a standard category assessed during the feasibility analysis phase of the System Development Life Cycle (SDLC). The common types of feasibility include economic, operational, and technical.

Question 19

A conversion strategy whereby the new system is first implemented in only part of the organization to solve any problems before implemented in the rest of the organization is called a:
A) pilot strategy.
B) phased strategy.
C) cutover strategy.
D) parallel strategy.

Accepted Answer

A pilot strategy is a conversion strategy where the new system is first implemented in only a part of the organization to identify any potential problems before it is implemented in the rest of the organization. This approach allows for a trial period to test the new system, identify any issues, and ensure that the system is working effectively before broad implementation. This can save time, resources, and potential problems in the long run. Therefore, the correct answer is A) pilot strategy.

Question 20

The following diagram depicts which of the following conversion strategies? 
A) parallel strategy
B) phased strategy
C) pilot strategy
D) entrepreneurial strategy

Accepted Answer

The diagram shows a phased strategy, where the conversion process is broken down into smaller phases or stages. Each phase is completed before moving on to the next one, allowing for a more controlled and manageable process. The diagram shows the four phases of the strategy: analysis, design, development/implementation, and evaluation.
