Client : Major Indian Software Company on behalf of a European leasing firm

A leading leasing firm in western Europe Germany which is part of one of the largest financial institutions in that region decided to migrate their legacy mainframe based applications built over the last 30+ years to a web-based solution.

The first phase of this assignment involved analyzing mainframe COBOL and MANTIS code of the legacy applications, drawing up program specifications and extracting the business logic of the programs. The objective of this reverse engineering exercise was to arrive at the Customer Requirement Specifications (CRS) for the existing leasing products of the firm. The CRS served as the basic input for the redesign and development of an enhanced web based leasing solution.

Following the reverse engineering and development of the CRS, a forward engineering exercise was undertaken to rebuild the entire leasing application to operate in a web-server RDBMS GUI environment.

VAST was associated with this assignment as a sub-contractor to the primary vendor for the assignment. VAST’s consultants were involved in reverse engineering both in leadership and detail level roles, forward engineering analysis, design, construction. Besides these, VAST provided leadership support to the client in managing an independent testing team for testing the newly built solutions prior to release to the internal integration testing team. In addition, teams of VAST’s senior consultants were involved in various phases of onsite analysis or delivery to the client.
