What are the Requirements?

Requirements are statements that describe the needs, constraints, and expectations of stakeholders for the system being designed. They represent the desired behavior, characteristics, and qualities that the system must exhibit to satisfy its users and stakeholders.

• Requirements are typically high-level and abstract, focusing on what the system should accomplish rather than how it should be implemented.
• Requirements serve as the foundation for the design process, guiding the development team in understanding the goals and objectives of the system.
• They provide a basis for making design decisions and evaluating whether the resulting system meets the stakeholders’ needs.

There are mainly two types of Requirements in System Design:

1. Functional Requirements: Specify the actions and behaviors the system must perform.
2. Non-functional Requirements: Define how the system should behave and perform rather than what it should do.

Understanding the distinction between requirements and features is crucial for successful project development. Requirements serve as the foundational criteria that outline what the system must achieve, encompassing the needs and expectations of stakeholders. On the other hand, features represent the specific functionalities or capabilities that fulfill these requirements, translating abstract goals into concrete components of the system.
