This paper represents the automobile product C84_X7094 used in the car conversion from a personal car to a delivery/cargo vehicle. This product is placed in the trunk of the car so that the car floor can bear more massive loads. The first part of the paper will describe Advanced Product Quality Planning (APQP). Companies use advanced product quality planning to ensure quality and efficiency and to encourage continuous improvement. The goal of product quality planning is to facilitate cooperation and communication between activities and to ensure that customer requirements are understood. After Advanced Product Quality Planning, the Production Part Approval Process (PPAP) will be described. It is a tool that serves to build trust in suppliers and their manufacturing processes because it is important that the parts have good quality and satisfy customer requirements every time. Obtaining PPAP is proof that the supplier has realized or exceeded the customer's requirements and that the process is capable of producing quality parts. The third part will describe Failure Mode and Effects Analysis (FMEA). The FMEA methodology is separated into two categories, Design FMEA and Process FMEA. The FMEA is aimed to enable the prediction of failures in the design phase by identifying all possible failures in the design or production process. The fourth part will cover the entire project design for product C84_X7094, from customer requirements to the production of the finished product. During the design of the project, all technical documentation should be reviewed and all critical product characteristics should be identified. The project is then approved by the technical office and a feasibility assessment is made. After that, the design and process FMEA and the technical and technological documentation with working instructions are made. In the end comes the prototype production, after which the customer confirms the quality of the product.
