For the development and execution of our projects D&D International Ltd. uses only ISO Certified Partners. Continuous external and internal Monitoring on Engineering and Production Process assures 100% Quality control. Each and every Supplier goes at least once a year through a complete Audit Approval Process carried out by ourselves and our Quality Partner in Bulgaria – TÜV Nord Bulgaria EOOD. All our partner suppliers must bring at least 20 years Experience in the relative field. In order to fulfill our engagement to the customer we design the ISIR Process as well as the internal and external Quality Inspection at our certified partner laboratories according to customer’s needs with regard to the affordable Approval Documentation. The PPAP and FMEA analysis are inevitable part of this process.
