What are the types of requirements?

Requirements come in several types:

• Functional — describe what the system should do (functions, processes, behavior).
• Non-functional — requirements related to the quality of the system: performance, security, usability, scalability.
• Business requirements — the goals and objectives of the business that the system should support.
• Technical requirements — constraints and standards related to the technology stack, integrations, infrastructure.
• User requirements — expectations and needs of end users.

Each type of requirement is important for a complete understanding and successful implementation of the project.
