Süsteemivajaduste

Süsteemivajadused refer to the requirements and specifications that a system must meet to function correctly and efficiently. These needs can be broadly categorized into functional and non-functional requirements. Functional requirements describe what the system should do, outlining its specific features and behaviors. For example, a functional requirement for an e-commerce system might be that users can add items to a shopping cart.

Non-functional requirements, on the other hand, define how the system should perform or its quality attributes. These include aspects such as performance, security, reliability, usability, and maintainability. A non-functional requirement for the same e-commerce system could be that the checkout process must be completed within 5 seconds.

Identifying and documenting system needs is a crucial step in the system development lifecycle. It ensures that all stakeholders have a clear understanding of what is expected from the system and provides a basis for design, development, testing, and validation. The process typically involves gathering information from users, business analysts, and other relevant parties through interviews, workshops, surveys, and document analysis.

Effectively managing system needs helps to prevent scope creep, reduce development costs, and deliver a system that meets user expectations and business objectives. Changes to system needs should be managed through a formal change control process to assess their impact on the project timeline, budget, and overall system design. Accurate and comprehensive system needs are fundamental to the success of any system development project.
