Which requirement type focuses on how a solution will operate?

The choice focusing on how a solution will operate is correct because solution requirements are specifically concerned with the characteristics and functionalities of the solution itself. These requirements detail how the system should behave, what functionalities it must provide, and the performance criteria that must be met in order to fulfill the needs of both the stakeholders and the business objectives.

Solution requirements can be further divided into two categories: functional requirements, which specify what the system should do, and non-functional requirements, which concern how the system performs its tasks, such as reliability, security, and scalability. By defining these aspects, solution requirements ensure that the solution is designed and implemented in a way that meets the operational needs identified during the analysis phase of a project.

In contrast, business requirements focus on the high-level goals of the organization and what the overall expectations are from a business perspective, rather than the specifics of the operational aspects. Stakeholder requirements represent what stakeholders need from the solution but do not detail how those needs will be implemented. Transition requirements address the conditions required to transition from an existing solution to the new solution, focusing on the implementation process rather than the operational functionality of the completed system.
