Aging Desktop Technology Gets a Modern Upgrade


A large integrated health care organization providing health care services, health plan financing, and health plan administration was challenged by an aging application enterprise application core to all aspects of their business. The legacy desktop solution was a highly customized vended system that grew to support more than 400 case managers and plan administrators, delivering healthcare to over a million patients. Since its debut, the legacy application had grown extensively to perform more functions to greater and more diverse user audiences, in some instances against the grain of the vended system’s architecture or typical customization patterns. The customizations made it increasingly difficult to add new features or make changes to current features as the organization’s needs evolved. Audiences and transaction types continued to extend within a navigational structure and user experience not originally designed for such extensive customization. Finally, the application was only available on a windows pc as a desktop application. With a growing employee base working remotely or on mobile devices, the application did not offer a solution. Recognizing that the critical-path application was in need of an overhaul, the organization partnered with sdg identify the best solution path and deliver a modern digital experience to users.

They envisioned a solution that would:

  • Provide a comprehensive patient dashboard eliminating multiple fragmented views
  • Streamline and improve workflows to provide users with a more intuitive experience
  • Allow user customized views and searches as needed to suit their roles and preferences
  • Enable granular role-based security to control access to sensitive data and functionality
  • Reduce the complexity and risk of deployments to improve overall speed and quality


Because of the inherent complexities of deploying a desktop application to hundreds of machines, release cycles were limited to once or twice a year. This meant that requested features and bug fixes could not be delivered to business users in a timely fashion. There were also concerns that the application wasn’t intuitive for the users and training on it took a long time to become proficient. sdg provided a technical architect and a business analyst who met with key stakeholders to gain understanding of the application and develop a solution path. The team recommended moving from a desktop platform to the web. This had the advantage of dramatically simplifying deployments, but it also presented a challenge in designing a web application with the performance characteristics of a desktop application. To this end, the team recommended that the replacement application be implemented as a Single Page Application (SPA) which allowed for very fast response times once the application was loaded into the browser. The development team of sdg and the client’s employees worked closely with stakeholders to refine and realize the future vision. The project went live and was extremely well received by the end users. The much-needed upgrade has positioned our client to more efficiently and accurately manage critical patient and case data into the foreseeable future.
