Discuss on TWO (2) justification of the use of Use Cases in requirement analysis.

 

The first step in user requirements analysis is to gather background information about the users and stakeholders and the processes that currently take place.

Stakeholder analysis identifies all the users and stakeholders who may influence or be impacted by the system. This helps ensure that the needs of all those involved are taken into account. If required, the system is tested by them. User groups may include end users, supervisors, installers, and maintainers. Other stakeholders include recipients of output from the system, marketing staff, purchasers and support staff. Stakeholder analysis identifies, for each user and stakeholder group, their main roles, responsibilities and task goals in relation to the system. One of the main issues is how to trade-off the competing needs of different stakeholder groups in the new system.
