Dental implant imalat endüstrisinde ürün iyileştirmesi için kalite fonksiyon yayılımı temelli karar verme yaklaşımı

Quality function deployment (QFD) is a great tool in translating customer needs into specifications into each phase. Based in Japan, QFD quickly spread to U.S. where it gained most of the popularity. This study subjects a SME in Turkey, who has ongoing research about the most important aspects to supply in dental implant industry before entering the market. Since the resources are limited, a study is going on to find the most important processes complying with customer needs and transferring them to manufacturing operations. Study includes a two-step QFD approach to for translating customer needs into quality characteristics. First step starts with extensive clinical and marketing research to figure out customer needs. This constructed the first WHATs of QFD chart. Second step contains using QFD in dental implant manufacturing. This step starts with another meeting between engineers and customers to find out design characteristics. This time customer needs turn into WHATs and design characteristics became HOWs. This step continues with transferring such aspects into manufacturing most important manufacturing operation is found. Finally, the relations between quality controls and manufacturing operations were inspected and the most important element is determined. Results are R&D, short length, CNC machining and geometric inspections in the most important process, quality characteristic, manufacturing process and quality controls respectively.
