A Gantt chart is a graphical representation of a project schedule that shows the start and finish dates of the project, as well as the completion time of specific activities. It allows the systems analyst to monitor the progress of the project and identify any delays or issues that need to be addressed. A work breakdown structure (A) is a hierarchical decomposition of the project into smaller, more manageable components. An event chain diagram (B) is a visual representation of the possible events that could impact the project's schedule. A risk register (D) is a document that identifies and assesses risks and outlines risk response strategies. "Select" (E) is not a valid option.

Question 5

With the _____ approach, an organization chooses an outsourcing company in any part of the world, as long as it can provide the needed services.
A) onshore outsourcing
B) nearshore outsourcing
C) offshore outsourcing
D) inshore outsourcing

Accepted Answer

Offshore outsourcing allows for the selection of outsourcing companies from any part of the world, which provides a wider range of options and potentially lower costs. Onshore outsourcing narrows the options to domestic companies, while nearshore outsourcing limits the selection to companies in nearby countries. Inshore outsourcing is not a commonly used term in the outsourcing industry.

Question 6

In the context of prototyping during the design phase of the systems development life cycle (SDLC), a _____ shows users how a particular task that was not technically feasible or appears to be unfeasible can be done.
A) proof-of-concept prototype
B) computer-aided prototype
C) requirements-based prototype
D) phased-in-phased-out prototype

Accepted Answer

A proof-of-concept prototype is designed to show users how a particular task that was thought to be technically unfeasible can be achieved. It demonstrates the basic functionality of the proposed system, and examines whether the desired outcomes can be achieved through the proposed technology.

Question 7

Which of the following is a common cost-effectiveness analysis method?
A) Consolidated rate of return
B) External rate of return
C) Corporate rate of return
D) Internal rate of return

Accepted Answer

Internal rate of return is a common cost-effectiveness analysis method that measures the profitability of an investment by calculating the discount rate at which the net present value of an investment equals zero. It is a widely used financial metric in investment analysis and is often used to compare the profitability of different investment opportunities. The other options listed (consolidated rate of return, external rate of return, and corporate rate of return) are not commonly used in cost-effectiveness analysis.

Question 8

In _____ of the implementation phase of the systems development life cycle (SDLC), as each module of a new system is converted, the corresponding part of an old system is retired.
A) parallel conversion
B) phased-in-phased-out conversion
C) plunge conversion
D) pilot conversion

Accepted Answer

Phased-in-phased-out conversion involves retiring parts of the old system in phases as corresponding modules of the new system are implemented, making it the appropriate option for the scenario described. Parallel conversion involves running both the old and new systems simultaneously for a period of time, plunge conversion involves immediately replacing the old system with the new one, and pilot conversion involves testing the new system in a small, controlled environment before rolling it out to the entire organization.

Question 9

The fundamental principle behind__________is that the self-contained blocks of codes can be reused in a variety of different applications, allowing new business processes to be created from a pool of existing services.
A) rapid prototyping
B) joint application design
C) service-oriented architecture
D) computer-aided systems engineering
E) Select

Accepted Answer

The principle described in the statement is the fundamental principle behind service-oriented architecture (SOA). SOA is a software design and architecture that emphasizes the creation of loosely coupled, reusable software services that can be used by multiple applications and business processes. Rapid prototyping, joint application design, and computer-aided systems engineering are all software development methodologies and processes, but do not specifically relate to the reusability of code blocks in the same way that SOA does.

Question 10

In _____ of the implementation phase of the systems development life cycle (SDLC), the old and new systems run simultaneously for a short time to ensure the new system works correctly.
A) parallel conversion
B) phased-in-phased-out conversion
C) plunge conversion
D) pilot conversion

Accepted Answer

Parallel conversion involves running the old and new systems simultaneously for a short period of time to ensure that the new system works correctly. This helps to minimize any potential disruption or downtime that may occur during the transition from the old system to the new system.

Question 11

Which of the following approaches for developing information systems increases the risk of leaking confidential information to competitors?
A) Insourcing
B) Outsourcing
C) Self-sourcing
D) Venture sourcing

Accepted Answer

Outsourcing involves the transfer of responsibility for system development and maintenance to a third-party vendor. In this process, data and confidential information may be exposed to the vendor's staff, which increases the risk of leaking confidential information to competitors.

Question 12

In the design phase of the systems development life cycle (SDLC), the _____ is an overview of the system and does not include hardware or software choices.
A) virtual design
B) physical design
C) conceptual design
D) logical design

Accepted Answer

The conceptual design is the initial stage of the design phase which identifies the main requirements and goals of the system. It does not involve hardware or software decisions and is only concerned with the overall concept of the system. Therefore, option C is the correct choice.

Question 13

__________is the approach where an organization's team develops an information system internally.
A) Insourcing
B) Outsourcing
C) Self-sourcing
D) Crowdsourcing
E) Select

Accepted Answer

Insourcing refers to the approach where an organization's team develops an information system internally. Therefore, option A is the correct answer. Option B (outsourcing) refers to the approach where an organization hires external vendors to develop their information system. Option C (self-sourcing) refers to the approach where individual departments or employees within an organization develop their own IT solutions without involving the IT department. Option D (crowdsourcing) is a process where an organization outsources the problem-solving process to the public or a community of users. Option E (Select) doesn't make sense in this context as it is not a relevant answer option.

__________is a series of well-defined phases performed in sequence that serves as a framework for developing an information system or project.
A) Rapid Application Development
B) Extreme Programming
C) The maintenance process model
D) The systems development life cycle
E) Select

Accepted Answer

The Systems Development Life Cycle (SDLC) is a series of well-defined phases (planning, analysis, design, implementation, and maintenance) performed in sequence that serves as a framework for developing an information system or project. The other options (A, B, C, E) are software development methodologies or models but not a set of phases or framework like SDLC.

Question 15

Which of the following statements is true of extreme programming (XP)?
A) Developers are allowed to go to the next phase before the completion of the current phase.
B) This method does not allow changes to a system after its delivery to the users.
C) Two programmers perform activities different from the other at different workstations.
D) A system's quality is improved by addressing major issues that have not been examined before.

Accepted Answer

Extreme programming (XP) aims to improve software quality and responsiveness to changing customer requirements by addressing major issues that have not been addressed in traditional methodologies. The other options are not true of XP. Option A goes against the XP principle of completing one phase before moving onto the next. Option B goes against the XP principle of embracing change. Option C goes against the XP principle of pair programming, where two programmers work together on the same workstation.

Question 16

Which of the following is categorized as a tangible benefit of an information system?
A) Improved employee morale
B) Better customer satisfaction
C) Increased company profits
D) Increased flexibility in business operations

Accepted Answer

Increased company profits are a tangible benefit as they can be measured in financial terms through an increase in revenue, cost savings, or other monetary gains. Improved employee morale, better customer satisfaction, and increased flexibility are intangible benefits as they are difficult to quantify in monetary terms.
