Requirements

Definition

Requirements are basically needs of the client which we need to fulfil to achieve the business or project goal.

The client’s needs can be fulfilled by gathering the essential requirements from the stakeholders to achieve the goal of the project.

In simple words, needs are high-level requirements that are segregated into many lower-level and more detailed requirements.
