This document is a guide that outlines the Vehicle Development Process (FVDP) utilized by FEV, an engineering and digital mobility company. The FVDP describes the workflows and interactions involved in vehicle development, structured around defined phases, organizations, and milestones. It emphasizes a highly integrated and simultaneous approach, covering the complete vehicle development lifecycle from concept development to vehicle launch. The guide details the key targets and objectives established at the onset of any vehicle development program, along with the implementation of a program timeline that incorporates an engineering gate process. Major milestones and engineering phases are also documented, providing a framework for best practice guidelines based on FEV's extensive experience in the automotive industry. The document serves as a comprehensive resource for understanding the complexities involved in modern vehicle development.
