dtr’s driver for the project was moving towards a standard company-wide set of credit rules. This would enable automatic approval for lower-risk clients and a simpler review process of higher-risk clients. SASIT brought in a team of three for the project, two senior RPG developers and a .NET programmer. The outcome was a greatly improved user experience, from the previous green screen look to that of a modern mobile device.
The integration of the IBM i to the new credit scoring engine web service was the most challenging part of the work and was written in RPG4 by one of our senior developers. By radically changing the user experience and redesigning the back end process, dtr has enjoyed efficiency gains, more flexibility and an improved customer experience. The business has also experienced substantial growth post implementation.
