Use of the modified delphi technique to develop elements of quality product design concept based on computer aided design (CAD)

Research output: Contribution to journalArticle

Abstract

Product Design is a transformation process of an idea about a product into an actual product. The process needs an explicit specification to sustain the quality of the product design. One of the design processes will apply computer-aided design (CAD) software to produce technical documentation. Therefore, identity establishes elements of the quality product design concept is needed to improve Malaysian design and technology trainees teacher. The modified Delphi technique has been conducted on 16 panels of experts, which invited from Malaysian Teacher Training Institute, local university, and industries. The expert committees answered the questionnaires given. The questionnaires applied Likert scale with five options (ranking from very important to very unimportant) for each statement. There were three rounds of modified Delphi surveys. The experts' committees rate 21 predetermined elements of quality product design based on CAD. However, the expert committee discusses and to add more elements of quality of the product design. Through the survey and discussion, the final finding show 22 elements of quality product design concept based on CAD has reached consensus. These elements will help to standardize the product design concept and assist Malaysian design and technology trainees’ teacher in producing quality product design.
