Use Case Analysis is a methodology used to identify, clarify, and organize system requirements by detailing the interactions between users and the system. It serves as a bridge between stakeholders and developers, ensuring that all functional requirements are captured and understood before system design begins.

Use Case Analysis

Methodology refers to the systematic, theoretical analysis of the methods applied to a field of study, encompassing the principles, practices, and procedures used to collect and analyze information. It provides the framework that guides researchers in selecting appropriate techniques and ensures consistency and validity in the research process.

System requirements define the essential specifications and conditions that a system must satisfy to function optimally, ensuring it meets user needs and business objectives. They serve as a foundational guide for system development, testing, and validation, helping to prevent project scope creep and ensuring alignment with stakeholder expectations.

Functional requirements define the specific behaviors and functions a system must perform to meet the user's needs, focusing on what the system should do rather than how it should do it. They serve as a foundation for system design, development, and testing, ensuring that the final product fulfills its intended purpose and user expectations.

functional requirements

System design is the process of defining the architecture, components, modules, interfaces, and data for a system to satisfy specified requirements. It involves a balance between technical feasibility, business needs, and user experience to create scalable, efficient, and maintainable systems.
