Method of assessing the quality of the design process of construction equipment with the use of DFSS (design for Six Sigma)

This paper presents the methodology for assessing the process of designing and constructing vehicles and machines, which implements Design for Six Sigma tools. An important purpose of this paper is to determine how defects affect the quality of the structure, based on the criteria of its conformance. The paper also presents the requirements needed to implement the method and the benefits arising from the use of quality assessment tools. The presented method enables the quality assessment of the design and construction process, which also serves as quality assurance method due to the possibility to avoid potential defects.

► Assessment of designing process enable to avoid potential defects.
► Quality of the designing process determines current customer satisfaction.
► Quality of designing process affects the quality of the designed mechanical unit.
► Assessing the design process prevents structural defects.
► Assessment of designing process represents the feedback from manufacturing process.
