The Open System Engineering Environment (OSEE) is an integrated, extensible tool environment for large engineering projects. OSEE is more than an integrated development environment (IDE), but is an integrated product life-cycle development environment. The system captures project data into a common user-defined data model providing bidirectional traceability, project health reporting, status, and metrics which seamlessly combine to form a coherent, accurate view of a project in real-time. By building on top of a central data model, OSEE provides an integrated configuration management, requirements management, testing, validation, and project management system. All of the components work together to help an organization achieve lean objectives by reducing management activities, eliminating data duplication, reducing cycle-time through streamlined processes, and improving overall product quality through work flow standardization and early defect detection.
