In an industry such demanding as the automotive one, where all big companies compete on a daily basis to get a greater market share than their competitors, there is a principle underlying to achieving the maximum profitability possible: looking for the best quality at the lowest possible cost. The aim of this project, performed at Johnson Controls Eurosit Barcelona Headquarters, is reinforcing the quality system for the detection and correction of defects in the finished product in order to fulfil some of the requirements stated on the corporate policies: the pursuit of excellence and the non-stop increasing of the quality standards. This Project seeks to achieve a more reliable, robust and accurate quality system. It also intends to improve the computerized traceability system to provide data management in real time, adapted to the needs of each situation analysis. All of the improvements and modifications are intended to achieve, as an ultimate goal, the reduction of the defects per seat to zero. Nowadays, the quality procedure involves a large number of manual operations: First, a few red moles are placed on the parts of the seat which are defective. After that, the operator records the defects data on a paper sheet. At last, the quality auditor introduces this information on the system. This means the human element is a major factor when evaluating. In order to minimise the "human-error" factor considerably, this system proposes the implementation of touchscreens in the workstations where the review is performed. The values will be recorded using a predefined list of defects, according to the model of seat being inspected. The seat information can be obtained from several ways: It can be obtained directly by reading the barcode label on the seat or by connecting to the Siemens PLC that manages the Assembly line operations. Once the defects are recorded and stored in the database, they will be displayed both in the subsequent repairing workstations and in the final verifications workstation. Additionally, the graphics of the production defects will also be shown all along the assembly line (they include the time and work shift where the defects have been produced). The reports of the defects and other statistics can be removed via Intranet.
