Six Sigma Approach

Persaingan yang sangat kuat diantara perusahaan yang semakin ketat terhadap produk yang sejenis di dalam hal menghasilkan suatu produk pasar nasional maupun internasional untuk pemasaran produk. Berdasarkan data yang didapatkan dari pengamatan pendahuluan yang dilakukan di PT. XYZ bahwa untuk setiap periode produk yang dihasilkan adalah diantara 2.500-4.000 unit produk. Salah satunya berdasarkan data produksi produk berupa sprocket gear sebagai objek penelitian, didapatkan data produksi pada bulan Maret 2016 sebanyak 3.050 unit dengan jumlah kecacatan mencapai sebesar 15% dari jumlah produksi sekitar 458 unit produk cacat. Penerapan metode lean six sigma dengan mengurangi lead time dan cacat pada produk pada proses produksi. Hasil dengan menggunakan distribusi normal yang terdapat pada batas kontrol dan mempunyai nilai ARL= 200 dan UCL = 12,78, namun tingkat sigma perusahaan dalam produksi produk sprocket gear diperoleh nilai sigma sebesar 3. Hal ini bahwa setiap 1.000.000 kali produksi menunjukkan kemungkinan mengakibatkan kecacatan diantara 70.675,1055 ~ 70.675. Hal tersebut memperlihatkan bahwa tingkat sigma perusahaan masih berada jauh dibawah rata rata karena tingkat sigma dalam persaingan yang terjadi secara global diantara perusahaan manufaktur sejenis, yaitu 4,0-4,5 Sigma.   Very strong competition among companies that are increasingly strict on similar products in terms of producing a national and international market product for product marketing. Based on data obtained from preliminary observations conducted at PT. XYZ that for each period the product produced is between 2,500-4,000 units of product. One of them is based on product production data in the form of gear sprocket as the object of research, obtained production data in March 2016 as many as 3,050 units with a number of disabilities reaching 15% of the total production of about 458 units of defective products. Application of lean six sigma methods by reducing lead times and defects in products in the production process. The results using the normal distribution found at the control boundary and have ARL = 200 and UCL = 12.78, but the sigma level of the company in the production of gear sprocket products is obtained by sigma value of 3. This is that every 1,000,000 times the production shows the possibility disability between 70,675,1055 ~ 70,675. This shows that the company's sigma level is still far below the average because the sigma level in competition that occurs globally among similar manufacturing companies, namely 4.0-4.5 Sigma.

This paper proposes a new Lean Six Sigma (LSS) methodology to improve process for clothing small- and medium-sized enterprise SME. The methodology is based on combination of two approaches which are the PDCA (Plan, Do, Check, and Act) and the DMAIC (Define, Measure, Analyze, Improve, and Control). The combination technique consists in applying the PDCA to continuously improve and control every DMAIC steps. The DMAIC approach has included Lean Six Sigma tools and techniques, as well as the success factors obtained from a survey, to improve its efficiency. The proposed approach is applied to improve the performances indicators such as Z sigma, Cp, cycle time, and lead time for the case of clothing SME in Tunisia. As an example, the Z-sigma has increased from the sigma level was improved from 1.45 to 3.85. The process capability Cp from 0.5 to 1.3 and the lead time was decreased from 39.47 days to 30.23 days. Finally, the study is concluded by sorting out the effects of the type of produced articles and the presence or not of the quality certification on the application of the proposed approach. The effectives from using PDCADMAIC technique are better when it’s applied with certified company, than non-certified one.

The main purpose of this research is to use “DMAIC” and “DMADV” framework of six sigma to reduce cost of projects, increase yields, improve performance and reduce defects. This study conclude that the sigma level of cement bag production in four production lines is “4.7 DPMO” values of 710 and the possibility of defects per unit of 11 possibilities this situation was handled by using six sigma. Any business or industry run only to satisfy customer and increase their profits, this can be attained as development of quality product..For the ranking of newly established universities the certification of those institutes is very important and also a critical process. For this process we used Lean six sigma approach that can identify the wastes that affect this process.Six sigma can be applied to any work field such as education, power optimization and other types of industries Six sigma “DMAIC” approach is also used for the testing of EDA tools that occurs due to the complex coding or configurations, flows and platforms they support. To improve the process quality of SDLC it’s necessary to remove the defects of system in advance along with thorough valuation of size and it also makes project accordant with real time environment

This paper presents the improvement of the procurement process for raw materials in a real manufacturing company supported by the Lean Sig Sigma as structured approach to deliver the improvement. The manufacturing company that is a subject of this paper have received a significant amount of complains regarding the internal purchase orders approval process and the overall procurement process of the company from both internal employees and external vendors and contractors. Considering that the company is procuring the raw goods from selected vendors, therefore the entire manufacturing plan depends on these materials, the company decided to improve this process trough Lean Six Sigma. The Lean Six Sigma approach was selected in order to obtain the improvement in a short time, based on indicators that were previously analyzed and prioritized. The paper focuses on simplifying of the process trough decreasing the number of mandatory steps.

Commercial banks and Bank Perkreditan Rakyat are two different types of banks whose existence in society aims to raise and channel public funds to improve people's lives. The facts show that there is a sharp competition between the two types of banks in terms of gaining public trust to become bank customer but although these two types of banks are different but still able to develop well in society. This study aims to identify the factors that become competitive advantage at Commercial Banks and Bank Perkreditan Rakyat from the customer's point of view based on customers' perceptions, expectations and interests so banks can determine competitive strategy. The approach used in this research is Lean Six Sigma approach with a sample of 60 respondents consisting of 30 customers of Commercial Banks and 30 customers of Bank Perkreditan Rakyat. Respondents will be asked to respond to research instruments based on their perceptions, expectations and interests. The results of the study there are five competitive advantages in Commercial Banks (1) promotions made, (2) reward appeal, (3) saving security, (4) cleanliness and comfort of the room, (5) friendliness, courtesy and neatness. Bank Perkreditan Rakyat obtained competitive advantage that is (1) cleanliness and comfort of the room,(2) ability and alertness of the officers, (3) friendliness, courtesy and neatness, (4) saving security, (5) familiarity  of the officer with the customer. In addition there are similarities there are interesting differences that is on the excellence of promotional activities and the attractiveness of prizes at Commercial Banks. and the familiarity of officers with customers at Bank Perkreditan Rakyat.
