Legacy Systems Modernization for Global Clients
Client Background
Our client, a commercial process improvement company based in Utah, United States, specializes in delivering process simulation software, training, and model-building services to various clients, including large commercial corporations, government agencies, and government-contracted agencies.
The Challenge
The client faced critical issues with their existing application, developed using VC++ and C#. The primary objective was to migrate the legacy application to updated language versions while improving existing functionalities. Challenges included a fragmented codebase, an excessively large code image (80 GB), complex workflows due to tightly coupled modules, a lack of comprehensive documentation, external library issues, and ongoing UI/UX change demands.

- Updating VC++ and C#: Upgraded VC++ and C# to their latest versions (C# from 2008 to 2022), ensuring compatibility with modern development standards and access to the latest features.
- Codebase Optimization: Consolidated the fragmented codebase, unifying multiple branches, and introduced comprehensive commenting for improved readability and collaboration.
- Code Image Reduction: Implemented advanced optimization techniques to significantly reduce the size of the code image, improving performance and scalability.
- Workflow Refinement: Decoupled tightly coupled modules to create a more stable and adaptable workflow, minimizing disruptions.
- Documentation and Standardization: Implemented a comprehensive documentation strategy and introduced standardized development practices. Enhanced team communication to address previous barriers.
- External Library Management: Conducted a comprehensive audit of external libraries, updating and managing dependencies to ensure compatibility and streamline the project structure.
- UI/UX Enhancement: Adopted an agile approach to incorporate evolving design requirements, ensuring the application aligned with current design trends and enhanced user experience.
