Final answer:
Operational and technical are the two types of requirements needed for analysis in system design or business analysis. Operational requirements deal with day-to-day functions, while technical requirements are about system construction and maintenance. Information is gathered through observation, surveys, and interviews. The correct answer is option (D).
Step-by-step explanation:
The two types of requirements needed for analysis in the context of system design or business analysis are operational and technical requirements. Operational requirements are related to the day-to-day functioning and management of the system, addressing how the system will perform under normal conditions. On the other hand, technical requirements focus on the system's architecture, components, interfaces, and data processing capabilities, which are essential for the system's construction and maintenance.
It is crucial to understand these requirements thoroughly as they inform the basis of system functionality and user interactions. Gathering this information can be done through various methods such as observation, surveys, and interviews with stakeholders. These techniques help in gaining a comprehensive view of what is required from the system both from an operational perspective and a technical standpoint.
