Which fact-finding technique helps a systems analyst understand how the current system is supposed to work?

The fact-finding technique that helps a systems analyst understand how the current system is supposed to work is document review. This method involves analyzing existing documentation related to the system, such as user manuals, system specifications, process maps, and previous project documentation. Through this review, the analyst can gather detailed information on system functionality, processes, and intended user interactions.

Documentation provides a historical perspective and insights that may not be captured during discussions with users or stakeholders, as it reflects the original design intentions and specifications of the system. This helps the analyst form a clear picture of how the system is intended to function, identify any discrepancies between the actual operation and documented processes, and uncover areas that may need improvement or updating.

While other techniques such as surveys, interviews, and workshops can provide valuable insights, they primarily gather subjective opinions or current experiences rather than focusing on the original design and intent of the system. Document review stands out for its ability to ground the analysis in factual and established parameters of the system's intended operation.
