"Wai ting time (WT) at the emergency department (ED) is a global concern, emerging evidence indicates that a wait for care delivery may result in adverse patient outcomes. Discrete-event simulation model has been developed to redesign the existing ED based upon several inputs (i.e. historical data, staff survey, and interviews). Furthermore, a newly developed simulation model was proposed, verified, and validated using triaged management system based upon Manchester triage system. The simulation study was performed as a part of design for six sigma project to create the proposed triage process. The proposed model resulted in reducing WT by 61% and length of stay (LOS) by 34%. In return, the sigma level was improved from 0,66 to 5,18 and from 0,58 to 3,09 for WT and LOS, respectively."

"In January 2005, to continuously improving and delivering the customer value, which helping customers and distributors to meet their needs and satisfaction, Company XYZ distributes the VOC (Voice of Customer) to Distributor ABC as a Local Distributor of Company XYZ in Indonesia for Specialty Chemicals Products. The feedback from Distributor ABC indicates that one key point, which considered as very important and prioritized to be improved by Company XYZ is the Order Lead Time.
As the response, Company XYZ in Indonesia, lead by Distributor Coordinator of Company XYZ initiates and performs this Six-Sigma Project to reduce the Order Lead Time. Order Lead Time is defined as the amount of time required from the submitted Purchase Order (PO) by Distributor ABC to the time the Distributor ABC received the order. The term and condition of the Order from Distributor ABC to Company XYZ is Free On Board (FOB) Singapore. The scope of the project will be limited to the Consumable Products imported from Manufacturing/Blending Plant located at China, which contribute about 75% of total products ordered by Distributor ABC.
The Distributor ABC expects to have fast and on time delivery, in order to have a better management of local inventory in Indonesia, and reducing the inventory level in the warehouse that in return will significantly reduced the inventory cost. To anticipate late delivery to the End Customer, Distributor ABC provides 3 months of inventory level at the warehouse in Indonesia.
To find the best solution on how to reduce the Order Lead Time, the problem solving methodology of Six-Sigma DMAIC (Define-Measure-Analyze-Improve-Control) has been using as a tool to find the source of variation, solving the problem, and improving the existing process. The project is based on the baseline data from October 2004 to March 2005 and project implementation from April to September 2005.
The Six-Sigma Project result shows that the major problem was occurred due to the availability of the raw material in Company XYZ Blending Plant at China and the availability of products in the Warehouse of Company XYZ at Singapore and China. Thus, as the consequences, the products should be produced "Just in Time" at the Blending Plant in China that obviously prolongs the Order Lead Time, especially when the raw material is not available.
Based on the result of Six-Sigma Project, the best solution to reduce the Order Lead Time and to manage the inventory Control is by using a Forecast Order. Forecast Order will help Company XYZ to manage and provide buffer stock at Singapore and China Warehouse and also prepare the raw material in the Blending Plant at China. Since the products are available in the Company XYZ Warehouse, the Order Lead Time to Distributor ABC could be reduced.
The implementation of Forecast Order and inventory management has been giving a significant impact on the Order Lead Time. The implementation of the Forecast Order in April till September 2005 shows that the Order Lead time can be reduced from the average of 45 days to 17 days. Distributor ABC is also able to reduce the inventory level at the warehouse in Indonesia from 3 months to 1 month. The inventory cost could be reduced by approximately 73%."

"Tulisan ini merupakan suatu pentaburan penerapan metodologi Six Sigma dalam upaya perbaikan proses dengan studi kasus proses pemotongan material dengan mesin Eye Tracer di lini persiapan bahan PT. United Tractors Pandu. Pada psrbaikan proses ini dilakukan penggunaan tahapan Six Sigma yang dikenal sebagai DMAIC (Define-Measure-Analyze-Improve-Control), dimana dalam tiap tahapannya digunakan berhagai kombinasi metode ataupun alat (tools) baik yang bersifat kuantitatif maupun kualitatif secara feksibel dan koutekstual. Dengan penggunaan metodologi Six Sigma, dihatapkan akan terjadi perbaikan proses k arah proses tampa cacat (zero defect) atau secara realistis mencapai 3,4 cacat per juta kemuugkinan (DPMO) pada saat suatu proses telah mencapai tingkatan enam sigma (Six Sigma).
Usaha peningkatan kualitas produk ataupun jasa yang ditawarkan kepada konsumen dalam era yang semakin kompelitif merupakan sesuatu yang mutlak perlu untuk dilakukan oleh setiap perusahaan. Demikian pula halnya dengan kuntitas produk yang dihasilkan oleh PT. United Tractors Pandu Produk setengah jadi yang dihasilkan oleh proses pemotongan dengan mesin Eye Tracer pada Lini Persiapan Bahan di perusahaan ini baru mencapai 3 sigma, yang menandakan masih terdapat sekitar 66.800 kejadian cacat dalam satu juta kemungkinan yang ada (DPMO). Banyaknya jumlah kejadian cacat yang ditemukan pads proses pemotongan tersebut, umumnya disebabkan oleh permasalahan metode dan permasalahan permesinan.
Melalui penerapan melodologi Six Sigma, sepedi dalam penelitian ini, diharapkan akan mampu meningkatkan nilai sigma proses pemotongan menjadi 3,5 sigma, yaitu 22-800 kejadian cacat dalam satu juta kCHl H. Peningkatan tersebut dapal diwujudkan melalui pengaplikasian usulan-usulan perbaikan yang berupa pembuatan prosedur standar opcrasi (SOP), perbaikan meja polong, maupun berbagai perbaikan lain yang digabarkan dalam tulisan ini.

This writing will explain in details about the implementation of Six Sigma methodology in order to make an improvement of cutting process by using Eye Tracer cutting machine in material preparation section, PT. United Tractors Pandu. This irnprovement method are using Six Sigma improvement stem which known as DMAIC (Define-Measure-Analyze-Improve-Control). In every those step, there would be a different methods and tools flexibly and eontextually used, which differ into quantitative or qualitative characteristics. By using Six Sigma methodology, we will go to achieve zero defect process or realistically 3,4 defect per million opportunity (DPMO) when the process has gain six sigma level.
All effort to increase a quality of products or services offered to customers was something really need to be done by many companies in this fast growing competitive market, including PT. United Tractors Pandu. As this far, semi finish product produced by Eye Tracer cutting machine which located in material preparation section., still only have 3 sigma in their process capability. This 3 sigma shows that there is a possibility of 66.800 defect was found in a million opportunity (DPMO) of their semi Enish product. The large number of defect found in that cutting process was identiiied mostly caused by cutting method and machinery problem.
By using Six Sigma method in this research, hopefully the company could eliminate those problems, and could increase the sigma capability into 3,5 sigma, which means there would be 22.800 defect occur in a million opportunity- This target of improvement could be realize by implementing the solutions given, like establishing a standard operating procedure (SOP) for cutting process, cutting table changing, and many other solutions proposed.
