What kind of requirements do models typically focus on?

Models typically focus on features or functions of an enterprise because they are designed to capture and represent how the system will behave and what it will deliver. This approach allows stakeholders to visualize the system's functionality, which aids in understanding how various components will work together to meet business objectives.

Models often emphasize the interaction between components, user interfaces, and workflows. By concentrating on features and functions, models provide a clear picture of the system's capabilities, which is crucial during the requirements gathering and analysis phases. These representations can take different forms, such as use case diagrams, flowcharts, or data models, making them a versatile tool for ensuring that all parties have a shared understanding of what the system should achieve.

Other types of requirements, while important, are generally not the primary focus of modeling efforts. Security requirements, cost-related requirements, and legal compliance requirements can emerge as secondary considerations during the process of defining the system but are typically examined through other means, such as risk assessments, financial analyses, or compliance checklists. Thus, the focus on features and functions in models plays a key role in successful requirements analysis and design definition.
