Requirements are the specifications of a product or service that must be met in order for it to be successful. They are typically documented and agreed upon by stakeholders before development begins.
Requirements are the specifications that define the characteristics of a product or service. They are the basis for the design, development, and implementation of a product or service. Requirements are typically expressed in terms of what the product or service should do, how it should do it, and what it should look like.
Requirements are used to define the scope of a project, to ensure that the product or service meets the customer’s needs, and to provide a basis for testing and validation. Requirements can be divided into two categories: functional requirements and non-functional requirements.
Functional requirements define the features and capabilities of a product or service. They describe what the product or service should do and how it should do it. Examples of functional requirements include user interface design, data storage, security, performance, scalability, and reliability.
Non-functional requirements define the quality attributes of a product or service. They describe how the product or service should look and feel, and how it should behave. Examples of non-functional requirements include usability, maintainability, portability, and extensibility.
Requirements are typically documented in a requirements document, which is a document that describes the product or service in detail. The requirements document should include a description of the product or service, a list of functional and non-functional requirements, and any constraints or assumptions.
Requirements are an important part of the software development process. They provide a basis for design, development, and testing, and ensure that the product or service meets the customer’s needs. Requirements should be documented, reviewed, and approved before any development work begins.
