Integration of Quality Function Deployment and TRIZ Methodologies to Design a Sanitary Part

A typical definition of New Product Development is a series of actions that begins with the identification of a market opportunity and concludes with the creation, marketing, and delivery of a product. It is a knowledge-based process where constraints and needs are converted into a product description. The competition for businesses now centers on innovation and new products. Industries and investors are constantly looking for new upgrade methods and/or equipment to reduce costs and increase capability. One industry in Indonesia that has a tight competitive level is the ceramics industry with a growth rate of 10% per year. The main objective of this study was to create the design of specific machining sanitary Spare Parts production due to complexity of the design. In the proposed methodology, Quality Function Deployment is used to convert the subjective requirements from users into an objective technical response. Theory of Solving Problem Inventively is used to enhance the subpar design by reducing system conflicts and creating a balanced solution between two requirements. The implications of the integration of Quality Function Deployment and Theory of Solving Problem Inventively in this paper are a product design and concept of the specific machining for sanitary spare parts that have been adjusted to the needs of users.
