Complex systems have always existed but in recent times, there has been a profound increase in the level of complexity with which most defense companies must cope. Model based systems engineering enabled by the 3DEXPERIENCE platform simplifies product complexity by enabling the entire framework of defining requirements to the product delivery on one holistic framework. Due to this, all stakeholders could collaborate using one 3D model as they develop their product. With this approach, leading companies can design, develop, test, prototype, simulate in a virtual environment and verify fit, form, and function to eliminate errors early in the development cycle.
