A U.S. Logistics firm plans to update and upgrade its COBOL VSAM Payroll system which is used to pay its 600,000+ employees. The mainframe assessment will include the standard isolation of the subsystems within payroll and will also include Business Rules isolation/extraction with Field Definition consolidation in preparation for the redesign/rewrite. Modern Systems’ eav Suite will be used to perform the automated process of gathering and documenting the business rules and field definitions. eav takes the guesswork out of enhancement planning. Both business and technical analysts have full visibility into complex legacy applications, and can predict the impact of specific changes across the environment.
