What types of requirements exist?

There are several types of requirements that are usually distinguished in system analysis:

1. Functional requirements — describe what the system should do, what functions and tasks it should perform. For example, "the user should be able to register".

2. Non-functional requirements — define the quality of the system, constraints, and characteristics such as performance, security, usability.

3. Business requirements — reflect the goals and objectives of the business that the system should support.

4. User requirements — describe the expectations and needs of end users.

5. Technical requirements — concern technical aspects of implementation, such as technologies used, compatibility.

6. Constraints — conditions that limit the project, such as budget, deadlines, regulatory requirements.

Understanding and properly dividing requirements helps create more accurate and effective solutions.
