Track: Six Sigma

Abstract

This project aims to address non-compliances in 3D feature based Computer Aided Design (CAD) models and drawings that are delivered to the customers under agreed Technical Data Packages (TDP’s), at the various conceptual, developmental and production levels of a company. It has been found that over 20% of all models in the TDP has shown evidence of non-compliance. This results in profit losses, lost time and morale of employees. The DMAIC Six-Sigma approach was used to define the problem, measure the extent of the problem, analyze the problem, attempt to identify root causes, find solutions to reduce the effects of the problem, and finally, sustain the improvements made. Various six-sigma tools like project charter, operational definition, control charts, fish-bone analysis, etc. have been used to improve the non-compliance situation. After implementing the improvements discussed in this project, there has been a significant reduction in the number of non-compliances, validated through statistical quality control tools. On the whole, this project has helped acquire a deeper insight of the application of six-sigma DMAIC approach.
