Question 1

Identifying mandatory features by surveying users and other stakeholders who have been involved in requirements determination would occur:
A) near the end of the analysis phase, after all requirements have been structured and analyzed.
B) near the end of the project identification and selection phase, after a formal request to conduct a project to design and develop an information systems solution has been approved.

Question 3

The minimum requirements for the new system are called:
A) essential features.
B) desired features.
C) minimum features.
D) mandatory features.
E) designated features.

The term "minimum requirements" implies that these features are mandatory or indispensable for the new system to function properly. Therefore, the best choice is D, mandatory features.

Question 4

Shaping alternative system design strategies involves:
A) enumerating different potential implementation environments.
B) proposing different ways to source or acquire the various sets of capabilities for the different implementation environments.
C) dividing requirements into different sets of capabilities.
D) all of the above.
E) none of the above.

Accepted Answer

Shaping alternative system design strategies involves all three options, i.e., enumerating different potential implementation environments, proposing different ways to source or acquire the various sets of capabilities for the different implementation environments, and dividing requirements into different sets of capabilities. By doing so, organizations can assess different options and choose the best approach to deliver the system as per the requirements.

Question 5

Which of the following types of alternatives represent compromise solutions?
A) Low-end alternatives
B) High-end alternatives
C) Midrange alternatives

Midrange alternatives represent compromise solutions as they typically balance factors such as cost, performance, and features to provide a solution that meets the needs and expectations of most stakeholders. Low-end alternatives sacrifice performance or features for cost savings, while high-end alternatives prioritize performance or features over cost. Requirements-dependent and constraints-dependent alternatives may not always result in a compromise solution as they may prioritize specific requirements or constraints over other factors.

C) testing step of the implementation and operation phase.
D) project initiation and planning step of the planning and selection phase.
E) designing the human interface step of the design phase.

Accepted Answer

All of the listed factors are common constraints on systems development. Available financial and human resources can limit the scope of what is possible, elements of the current system that cannot change may need to be accommodated, legal and contractual restrictions must be adhered to, and there may be a deadline by which the current system needs to be replaced.

C) Mandatory features screen out possible solutions; essential features are those that users could live without.
D) Essential features screen out possible solutions; mandatory features are those that users could live without.
E) Desired features screen out possible solutions; mandatory features are the important capabilities of a system that will serve as the primary basis for comparison of different design strategies.

Accepted Answer

Mandatory features are non-negotiable and must be present, thus they screen out solutions that don't meet these criteria. Essential features are important for comparing different design strategies.

Question 15

The most conservative solutions in terms of the effort, cost, and technology involved in developing a new system are the:
A) low-end solutions.
B) high-end solutions.
C) mid-range solutions.
D) constraint-dependent solutions.
E) requirements-dependent solutions.

Accepted Answer

Low-end solutions typically involve using simple and well-established technology to develop a basic system that meets the minimum requirements. These solutions require less effort and are often cost-effective, making them the most conservative option. High-end solutions involve using advanced and expensive technology to create a system with advanced features, making them less conservative. Mid-range solutions are in between low-end and high-end and may require more effort and cost. Constraint-dependent and requirements-dependent solutions are not specific categories of solutions and do not indicate the level of conservatism.

Question 16

System features might include:
A) data kept in system files.
B) system outputs.
C) analyses to generate the information in system outputs.
D) expectations on accessibility, response time, or turn-around time for system functions.
E) all of the above.

Accepted Answer

System features encompass all of the listed options. Data kept in system files is a crucial component of the system which helps generate the desired system outputs. These outputs are the results of analyses conducted on the data to generate information. The system features are designed around certain expectations on accessibility, response time, and turn-around time for system functions, to ensure that the system meets the requirements of its users.

Question 18

The alternative that goes beyond simply solving the problem in question and focuses instead on systems that contain many extra features users may desire is referred to as a:
A) low-end alternative.
B) high-end alternative.
C) quality-focused alternative.
D) requirements-dependent alternative.
E) constraints-dependent alternative.

Accepted Answer

A high-end alternative goes beyond just solving the problem and offers additional features or capabilities that may be desirable to users. Low-end alternatives, on the other hand, are stripped-down versions that provide only the bare necessities to solve the problem. Quality-focused alternatives are more about ensuring that the product or solution meets certain standards, rather than offering added features. Requirements-dependent and constraints-dependent alternatives are not relevant in this context.
