The synchronization of engineering, procurement, and project management activities is a growing problem for engineering-driven businesses working in project-based contexts, especially those concentrated on prototype development and small-series manufacturing. Frequent design iterations, changing product architectures, and high levels of technical uncertainty in these situations frequently result in fragmented information flows and poor cross-functional coordination, which have a negative impact on cost management, traceability, and decision-making. The fragmentation of information systems and processes is the main root cause of cross-functional misalignment, according to this thesis, which examines these issues in the industrial setting of Podium Engineering. A PLM-centered integration framework that uses Product Lifecycle Management as a unifying backbone to allow coherent data management across the project lifecycle is suggested based on this study.
