(Design and Developed Product the Kindergarten Classroom Furniture with Rubber Wood Using Quality Function Development)
Keywords:Quality function development, Classroom furniture, Kindergarten students, Rubber wood
This research is to apply a Quality Function Deployment (QFD) technique for designing and developing rubber wood furniture of a kindergarten classroom. The objective of this research is to design and create the classroom furniture by focusing on the shape and usability according to the user requirements. The methodology began with a survey in the kindergarten classroom instruction in order to specify of the sample groups. After that the user requirements were collected by using the designed questionnaires. The collected data from the questionnaires, such as the importance requirement scores, was calculated and then analyzed by the QFD technique. The analysis of QFD technique was divided in to two matrixes, including the furniture product planning matrix and the furniture part deployment matrix. The furniture product planning matrix was related to translate the user requirements to the technical requirements, while the furniture part deployment matrix was about the translation of the technical requirement to the part characteristics. The results of this research showed that the QFD technique was able to design and develop the shape and usability of the kindergarten classroom furniture that responded to the user requirements. The survey results from the users revealed that the average of satisfaction values in case of all new products were greater than that of the previous products from 3.437 scores to 4.373 scores, which increased approximately 22.23 percentage.
