| dc.description.abstract | Six Sigma was originated in the 1980s by Motorola. This method improves the production efficiency by statistical tools. Many companies improved production efficiency and make process more flexible by six sigma.
This study used six sigma to improve the production process. The case study company’s production lines become overloading because of increasing number of order from the government. To enlarge the capacity of production line, the project members used six sigma DMAIC method to study and analysis in the process. 5W(what, who, when, where, why) and SIPOC (supply, input, process, output, customer) are used in the Define phase to define the challenges. Data collection and flow charts are used to measure the problems. The fishbone diagram and Barrydo diagram are used to find out the key factors that affecting feasible improvement schemes. In the Improvement phase, we use DoDAF(United States Department of Defense，DoD) system to present the operational view and systematic view, then implement a solution based on the analysis results of the systematic view and get significant improvement. Finally, in the Control phase, we submit a standard operating procedure to who will be involved into the process.
By applying this solution, the production efficiency was increased and the production cycle of multiple orders was reduced. Otherwise, there also provide the benefit of data correctness. | en_US |
