"You guys have been awesome to work with!" - Employer & Participant Services Supervisor of MN State Company


As a provider of benefits for employees of the State of Minnesota, they used an internal web application to automate business processes for retirement benefit counselors, auditors, and administrators. This application includes user interfaces and batch processes for preparing benefit estimates, annuitizing plan participants, processing refunds, and handling many other daily activities. The goals of the project included migrating off mainframe (with realized cost savings), eliminating the use of COBOL, and streamlining processes to improve efficiencies. In addition to that, the clients wanted the web application to improve internal controls, increase productivity by reducing or eliminating manual processes, and migrate as much functionality online as possible. 


While working on this project, Intertech collaborated with business analysts and users to identify requirements, design user interfaces, and workflows with Balsamiq Mockups. Our team implemented business logic in Java services using Spring and OpenJPA. Creating user interfaces was done using Spring MVC, Apache Tiles2, HTML, CSS, JavaScript, and JQuery. Furthermore, Intertech provided unit test coverage for all delivered code with JUnit and Mockito and also performed data modeling and class design with Dia and SQL Workbench. Throughout the rest of the process, Intertech managed to completely redesign the system’s user interface. They defined a service-oriented application architecture and took existing business rules from a legacy system to implement in a new system as applicable, eliminating redundant processes and automating others. The team used an iterative development and testing approach with defined milestones and implemented best practices.

Strictly following the given timeline, Intertech partnered with the IT client to replace a legacy mainframe system written in COBOL with a Java-based solution using an iterative approach. Intertech’s consulting unit provided architectural guidance and development staff, comprised of two teams. Intertech personnel worked closely with the Minnesota State company’s business analysts and users to understand current processes and offer recommendations for increased efficiencies where it made sense. Many things resulted from Intertech’s cooperative work. The outcome produced: • Automation of manual processes • Workflow and audit tracking of previously ad-hoc processes • Reduced dependence on system admin staff by enabling users to perform more tasks • An internal staff very knowledgeable on the new system.
