Tarkvaranõuded

Tarkvaranõuded describe the functionalities and constraints of a software system. They are crucial for defining what the software should do and how it should perform. Requirements can be broadly categorized into functional and non-functional. Functional requirements specify the services the system should provide, detailing inputs, behaviors, and outputs. For example, a functional requirement for an e-commerce site might be that a user can add items to a shopping cart.

Non-functional requirements, on the other hand, define qualities and constraints of the system rather than specific functions. These include aspects like performance, security, usability, reliability, and maintainability. An example of a non-functional requirement could be that the website must load within 3 seconds.

The process of gathering and documenting software requirements is known as requirements engineering. This involves eliciting needs from stakeholders, analyzing them for clarity and completeness, specifying them formally, and validating that they accurately reflect the desired system. Poorly defined or missing requirements are a common cause of software project failure, leading to scope creep, budget overruns, and dissatisfied users.

Effective requirements management ensures that requirements are tracked throughout the development lifecycle, changes are controlled, and the final product meets its intended objectives. They serve as a foundation for design, development, testing, and ultimately, user acceptance.
