What is the first step in the systems analysis phase?

The first step in the systems analysis phase is requirements modeling, which is crucial for understanding the needs and expectations of stakeholders regarding the system being developed. During this phase, system analysts gather, define, and document the requirements to ensure that the final system aligns with the user's needs and objectives.

This process involves techniques such as interviews, surveys, and observation to capture all relevant information effectively. By accurately modeling the requirements, analysts can establish a clear framework for what the system must achieve, which sets the foundation for further phases, including design and implementation. This step is vital because any misunderstanding or oversight in requirements could lead to significant issues later in the development process, such as missed functionalities or user dissatisfaction.

The focus on requirements modeling as the initial step highlights the importance of establishing a solid understanding of what is needed before proceeding with design or implementation, ultimately leading to a more successful system development life cycle.
