Yeni ürün uygulama sürecinin performans değerlendirmesi için ileri ürün kalite planlaması ve bir fabrikada uygulama

Each product is considered as new product in companies with order-based production system and challenges of not only producing new products but also changing market and competitive conditions are faced. In order to overcome these difficulties and sustain market share, to produce high quality products at one time with minimum cost in all stages in production of new products is necessary. In attempt to solve this critical problem, our study focuses on advanced product quality planning (APQP) technique in new product development (NPD) process to ensure survival and continuous improvement of company and reduce cost, time, labor and customer losses. In this study, firstly NPD process and use of APQP in NPD were explained and then example of APQP application in factory producing heat exchangers with order-based production system was given. APQP has been completed in five sections. The first two parts of APQP are related with product design. Since the company doesnot have design responsibility and it belongs to the customer, the documents of the first two sections have been provided by the customer. Three main sections of the other APQP application were realized in the company. These sections include; process design and development, product and process validation, feedback and corrective actions. Process management and control activities and tools such as establishment of team, selection of NP, feasibility studies, determination of workflow, reduction of risks, determination of process capability, measurement systems analysis, and control plan, production, dimensional and performance tests were performed. As a result of this study, it has been proved that NPs produced by following NPD process that is continuously evaluated with APQP method, fully meet both customer and company requirements. By using APQP method in NPD, process is controlled and scrap rates, costs and customer complaints are reduced.
