What is one of the primary activities during the systems analysis phase?

One of the primary activities during the systems analysis phase is requirements modeling. This phase focuses on understanding and defining what the system should accomplish by gathering detailed insights into user needs and system functionalities. Requirements modeling involves creating various representations of the requirements, such as use case diagrams, flowcharts, and specifications, which help clarify what features and capabilities the system must have. This is crucial because accurate requirements are the foundation upon which successful systems are built.

In contrast, other activities, such as system implementation, occur in later phases after the analysis has been completed. Project management, while essential throughout the entire project, is more about overseeing the process rather than analyzing system requirements specifically. Data collection could be considered a part of requirements modeling, but it is more focused on gathering information than modeling the gathered requirements for analysis. Thus, requirements modeling stands out as a key activity in the systems analysis phase.
