A data flow diagram is a graphical representation of the flow of data within a system. It shows how data is input, processed, and outputted in a system. This diagram is used to model and understand the processes and data flows within a system. Therefore, it can be considered as an example of a process model because it illustrates the various processes involved in the system and how they interact with each other.

Divide and conquer is indeed one of the underlying principles of systems development. This approach involves breaking down a complex problem into smaller, more manageable sub-problems, solving them individually, and then combining the solutions to solve the overall problem. It helps in simplifying the development process, improving efficiency, and promoting modular design. Therefore, the statement "Divide and conquer is one of the underlying principles of systems development" is true.

An information systems development project can help in correcting or improving the efficiency of people and processes. By analyzing current systems and identifying areas of improvement, the project can implement solutions that streamline processes, automate tasks, and enhance productivity. This can lead to more efficient use of resources, reduced errors, and improved overall performance. Therefore, the statement "Correcting or improving the efficiency of people and processes is one of the potential problems that may be addressed by an information systems development project" is true.

Cost-benefit analysis does not ensure that an information system is developed at a minimum cost. Instead, it is a technique used to evaluate the potential costs and benefits of a project or investment. It helps in determining whether the benefits of implementing the system outweigh the costs involved. The analysis takes into account various factors such as financial, social, and environmental impacts to make informed decisions about the project's viability. Therefore, the statement that cost-benefit analysis ensures minimum cost for system development is false.

The statement of work is not one of the deliverables of the problem analysis phase. The statement of work is typically a deliverable of the planning phase or the initiation phase in project management. During the problem analysis phase, the focus is on identifying and understanding the problem, gathering information, and conducting analysis to determine the root cause of the problem. The statement of work is usually developed after the problem has been analyzed and a solution has been determined.

A steering committee is typically composed of key stakeholders and decision-makers who oversee and guide a project or initiative. They are responsible for making strategic decisions, providing direction, and ensuring the successful implementation of projects. However, the given statement is false because a steering committee does not solely determine which requests and projects get approved and scheduled. While they may have influence and input in the decision-making process, final approval and scheduling typically involve other factors such as budget, resources, and organizational priorities.

The Capability Maturity Model (CMM) is not specifically focused on project management processes but rather on the overall maturity and capability of an organization's processes. While it can be applied to project management, its scope is much broader and encompasses various areas such as software development, systems engineering, and quality management. Therefore, the statement that CMM is solely intended to improve project management processes is false.
