By analyzing a final product the process of recreating a DESIGN is known as REVERSE engineering. Reverse engineering is the process followed in order to find difficult, unknown, and hidden information about a software system. It is important when software products lack proper documentation, and are highly unstructured, or their structure has DEGRADED through a series of maintenance EFFORTS. Maintenance activities cannot be performed without a complete understanding of the software system.
