Describe the viewpoints approach to requirements discovery, giving the types of viewpoint.(5 Marks)

The viewpoints approach to requirements discovery is a method that involves gathering requirements from various perspectives or "viewpoints". This approach is based on the understanding that different stakeholders will have different perspectives on the system, and these perspectives need to be considered to ensure that the system meets the needs of all users.

1. User Viewpoint: This viewpoint focuses on the needs and expectations of the end-users. It involves understanding how the users will interact with the system, what tasks they will perform, and what information they will need.

2. Business Viewpoint: This viewpoint considers the needs of the business or organization. It involves understanding the business processes that the system will support, the business rules that the system must enforce, and the business goals that the system should help achieve.

3. Technical Viewpoint: This viewpoint focuses on the technical requirements of the system. It involves understanding the technical constraints that the system must operate within, such as the hardware and software platforms that the system will run on, and the performance and security requirements that the system must meet.

4. Legal Viewpoint: This viewpoint considers the legal and regulatory requirements that the system must comply with. This could include data protection laws, accessibility standards, and industry-specific regulations.

5. Social Viewpoint: This viewpoint considers the social and cultural aspects that may affect the system. This could include the social norms and cultural practices of the users, as well as the social impact of the system.

By considering these different viewpoints, the viewpoints approach to requirements discovery can help ensure that the system meets the needs of all stakeholders.
