Application of QFD & VE & lean approach for control tests in a product design

Abstract

Purpose: of this paper consists of identifying and prioritising control tests of a product design with integrating QFD and VE techniques according to use of the lean approach to increase the productivity of product design. Design/methodology/approach: of this research is the application of four quality houses at QFD (four matrices) and VE matrix and assessment table of lean approach in the form of a combinational process. Findings: of this research were the implementation of mentioned methodology for numerical application. Bullet-head drill (27.8 inch HSD) that was applied in oil and gas industries with 5.69 scores is more than moderate in related to lean of control tests, and it is 7.13 from 9 for average survey results of applied mentioned methodology, and also it is 0.825 for research reliability. Research limitations/implications: of this paper suggest that the wide use of the other non-statistical techniques of quality engineering can be achieved with simple programming in excel and lean approach. Even more advanced topics in fuzzy circumstance can be applied with this methodology. Originality/value: of this research is extracted from three matrices of QFD, one matrix of VE and assessment table of lean approach for prioritising the control tests in product design of bullet-head drill 27.8 inch HSD.
