System modeling is used to implement findings and start over to ensure the system is understood. System modeling is an iterative process because information gathering is not a perfect process.

System modeling is used to implement findings and start over to ensure the system is understood. (Page 57)

Corporations are constantly evaluating their processes, changing or upgrading their management information systems, or implementing a new strategic initiative. These initiatives can sometimes be designed or deployed using information systems. Why is it important to use systems analysis in these circumstances?

Systems analysis is the process of analyzing organizational programs that can be solved with an information system. It is critical to understand the problem as a whole by defining the problem, looking at the underlying causes, and identifying a possible solution along with system requirements. The requirements will involve process development, information technology, and possible changes to the organization's management. (Page 55)

Which of the following best describes systems analysis as a general term? Systems analysis is a feasibility study. Systems analysis is used to analyze organizational problems. Systems analysis is defined by Systems Development Life Cycle.

Systems analysis is used to analyze organizational problems. (Page 55)

As previously discussed, corporations are always taking on new initiatives to remain competitive or gain a competitive advantage. When taking on an information system development project, it is necessary to evaluate the program. Describe why it is important to perform a feasibility study during the systems analysis phase.

Systems analysis necessitates the performance of a feasibility study to determine whether the solution is financially, technologically, or organizationally feasible. The objective is to determine whether the proposed system is a good investment, whether the necessary technology is available, and whether the organization can adapt to the changes introduced by the new system. (Page 57)

Complex corporate initiatives, such as software development or information system development, are managed as projects. Project management and the SDLC method are essential strengths in systems development. One way to manage a complex project is to evaluate and understand the project's critical path. Describe the benefits of applying critical path method (CPM) to complex projects.

The benefit of applying critical path analysis is that it defines the longest paths for each task, as well as calculates the earliest and latest dates each task. This process identifies tasks that are critical and those that cannot be delayed; it also identifies the tasks that can incur delays without adversely affecting the project. (Page 57)

In organizational management, two management models have influenced our understanding of the decision-making process. These models are called classical and behavioral. Describe the differences between these two models and provide examples where they can be applied.

The classical model of management describes the role of management within the context of four functions: planning, organizing, leading, and controlling. An example of the application of this model is the action of budgeting. Budgeting is part of planning. On the other hand, the behavioral model of management recognizes that actual management behavior is less systematic or predictable than classical management. Behavioral models can be applied in unstructured decisions. (Page 63)

The offering of product samples and trial versions is not a new concept, although with a digital market and digital goods, product quality and available features can be tightly controlled so that when a customer wishes to expand their usage of a product, they need merely pay a fee and the new features may be immediately available. Often with --------- pricing strategies, the core service might be free, but additional features and services may be available for a charge. Mobile phone apps and games are an example of this concept, where limited versions of software are available for free, but often charge a fee for full versions, additional features, or related digital goods.

User support after implementation is important because user adoption is critical for the success of any information system. Users often fail to adopt the new system because they were not properly trained, or because the system is different from the previous system. There are six methods to increase user adoption and lower post-implementation costs. What are the six methods, and which one do you think is the most important for driving user adoption?

The six methods include benchmarking, usability testing, user communication, forming an internal user group, planning, and leveraging existing resources. Benchmarking is critical because it teaches best practices. Usability testing is critical because there can never be enough testing. Communication among the users is most critical because communication is key for driving change acceptance. Forming user communities builds a support infrastructure. Finally, leveraging existing resources drives down cost. (Page 59)

The waterfall model is a type of systems development life cycle model. Which of the following is true about the waterfall model? The waterfall model is a non-sequential development process. The waterfall model is most appropriate when system requirements are clear, well-documented, and unlikely to change. The waterfall model is easy to manage due to the rigidity of the model. The waterfall model consists of five stages that follow the criteria of the SDLC model.

The waterfall model is most appropriate when system requirements are clear, well-documented, and unlikely to change. (Page 56)

When corporations embark on an information system development project, it is necessary to evaluate the program, its objectives, and how to approach development. There are methods to keep control and monitor project schedules, effectiveness, and cost. One of these methods is the waterfall model. Can you describe a scenario in which the waterfall model would be most appropriate?

The waterfall model is most appropriate when system requirements are clear, well-documented, and unlikely to change. This model is also useful when the technology is understood and will not change, when the project is relatively short term, and when sufficient resources and expertise are available to support the process. The waterfall model includes stages that must be completed prior to moving forward to the next stage, moving in a flow that is similar to a waterfall. (Page 56)

Analytics would affect the database performance

Why is it not good practice to perform analytics on a online transaction processing database?

Computer-aided software engineering (CASE) is the use of computer methods to organize and manage software development in information systems. CASE software can be classified into three categories or hierarchies: tools, workbenches, and environments. Please describe the types of tools in each category.

There are six types of CASE tools and CASE workbenches: business analysis or graphic modeling; development; verification and validation; configuration management; metrics and measurement; and project management. There are five categories of CASE environments: toolkits, fourth-generation, language-centered, integrated, and process centered. (Page 61)

When designing an information system, it is imperative that security is planned and addressed at the system level. System level security consists of the architecture, policy, and processes that establish the security on computer systems. No matter how much time is spent analyzing and designing security protection, the system will always have a risk of being breached. Describe the three levels of risk when performing risk management analysis.

There are three levels of risk for system security: low, moderate, and high. Low-level risks have a noticeable impact and possible damage. Low-level risks can affect the short-term performance of a business. A moderate-level risk is very serious and would result in severe impairment, adversely impacting the organization's operations. A high-level risk would result in complete loss of capabilities. The resulting damage from a high-level threat could threaten public safety or economic stability. (Page 59)
