what are application- level requirements
Application-level requirements refer to the specific functionality, features, and characteristics of a software application that are necessary for it to meet the needs and expectations of its users. These requirements define the overall behavior and capabilities of the application.
To determine and define application-level requirements, follow these steps:
1. Requirements Elicitation: Begin by gathering information from stakeholders such as users, customers, and subject matter experts. Conduct interviews, surveys, workshops, and other techniques to understand the needs and expectations of the application.
2. Requirement Analysis: Analyze the gathered information to identify, categorize, and prioritize the requirements. This involves understanding the context, business goals, user roles, and user interactions with the application.
3. Requirement Specification: Document the requirements in a clear and concise manner. Use techniques such as use cases, user stories, and functional and non-functional requirements to describe what the application should do and how it should behave.
4. Requirements Validation: Review and validate the requirements with stakeholders to ensure they are accurate, complete, and consistent. This can be done through walkthroughs, peer reviews, and user feedback.
5. Requirements Management: Continuously manage and track the requirements throughout the software development lifecycle. This involves maintaining traceability, handling changes, and ensuring alignment with project goals.
Examples of application-level requirements could include:
- Functional Requirements: Specify what the application should do, such as user authentication, data entry forms, search functionality, reporting, or integration with other systems.
- Performance Requirements: Define the expected response time, throughput, and scalability of the application, as well as any resource constraints.
- Usability Requirements: Describe the user interface design, navigation, accessibility, and overall user experience goals.
- Security Requirements: Address authentication, authorization, data protection, and other security measures to ensure the application is secure.
- Compatibility Requirements: Specify the supported platforms, operating systems, browsers, or devices the application should work on.
Remember, application-level requirements should be specific, measurable, achievable, relevant, and time-bound (SMART) to ensure they can be effectively implemented and tested.
