Aspect Forward Tracing (Information System) Backward Vouching (Information System) Direction of Analysis Tracing data flow from the original input of the information system toward the final system output. Tracing system outputs or reports backward to the original input data. Starting Point User input interfaces, data entry forms, sensors, or source transactions. Reports, dashboards, logs, or database records produced by the system. Main Objective Verify that all input data is processed correctly and appears in system outputs. Verify that the outputs originate from valid and authorized inputs. Typical Data Flow Input Interface → Application Processing → Database Storage → Reports Reports → Database Records → Application Processing → Input Source Risk Detected Missing transactions, incomplete data processing, or unrecorded system inputs.
