Six sigma is a business management strategy and is used to improve the quality of the products and processes in many organizations. However traditional six sigma methodology, namely DMAIC, is not suitable for developing products. This paper investigates DFSS methodologies and presents a DFSS methodology for order based industry. Specifically, we suggest a customized DMADV method for order based industry and present a case study for developing a configuration optimization of the flying simulators.

The strategic aims of six sigma in the aspect of business is directly related with the result of the business by the creation of profit. So based on the reformatory strategy of management performed by each organization echelon, the improvement of management by objectives is proceeded actively. This thesis recognizes the need of educational Programme needful in performance of reformatory strategy of six sigma, and concludes the strategic values as the criteria. In audition this thesis presents the strategic tool fundamental to analyse the skills and methods practiced in the designing step of improving programme of results through the research.

This paper includes an example of applying Six Sigma to Non-function test process to improve the efficiency and reliability of the Ammunition Stockpile Reliability Program (ASRP). By applying the DMAIC which is one of the Six sigma methods. we found out the vital few and as an improved version : effective redesign of check-sheets, pre-examination of technology, on-the-scene support system. As a result, we could enhance the reliability and reduce manpower and additional expenses.

우리나라의 최대 철강회사인 포스코는 2005년부터 품질개선을 위해서 포스코 자체의 혁신방법론인 QSS+(Quick Six Sigma)을 개발하여 실시하고 있다. QSS+는 회사 전체 직원이 개선 실천 학습을 하고, 지속적인 낭비제거를 통해 부가가치를 창출하는 활동으로 '일상개선 활동, 과제 활동, 솔선/격려활동, 인재양성' 4개의 축으로 운영되고 있다. 또한 QSS+는 오랜 시간에 걸쳐 정착되어 정부 기관, 기업, 그룹사, 외주파트너사, 공급사 및 다양한 분야에서 우수 혁신 활동 사례로 벤치마킹을 실시하고 있다. 매년 현장에서 활동하는 포스코 QSS+ 현 수준을 정확히 판단하고 향후 방향성을 제시하는 QSS+ 충실도 평가 기준을 개선하기 위하여 AHP 분석 방법을 통해 평가 항목을 분석하고 현장이 반영된 'QSS+ 평가 기준'을 제시하고자 한다.

This paper is concerned with a six sigma application to non-manufacturing process. Based on the comparison to manufacturing process, non-manufacturing process has some specific characteristics. The main focus of this study is to introduce an empirical case study on the implementation of DMAIC procedures for non-manufacturing process. We use a simple and practical road map which consists of 13 steps. Some fundamental rules for DMAIC implementation in six sigma projects are also introduced.

Today, many companies will be isolated in competition if they do not have competitive power to overcome quick change and big crisis of market. Nowadays, globally high-grade companies have done their best for increasing their competitive power through a many kinds of methods in keen competition for making of pacesetting position. This study focuses on distribution with the domains like capacity, layout, amount of location, assignment of product, operation procedure and operation rule in order to improve these domains, we make a further application of eight analysis ways based on DMAIC method for improving operation of processes of distribution center as the third profit source. The purpose of this study is to seek an approach that can easily adopt of Lean Six Sigma in operational management of distribution center by a kind of data, analysis method and template.

This paper considers a six sigma project for reducing the cost copper of the cable materials in a electric wire company. The project follows a disciplined process of five macro phases: define, measure, analyze, improve, and control (DMAIC). A process map is used to identify process input variables. Three key process input variables are selected by using an input variables are selected by using an input variable evaluation table: large cable, plating, and a twisted pair. DOE is utilized for finding the optimal process conditions of the three key process input variables. The implementing result of this six sigma project is enable for reducing of the 2.8% copper materials.

Since 1980's, many enterprises have constructed Strategy Information System and tried BPR, ISP. Also, they implemented ERP and practiced the Process Innovation and Six Sigma for Management Innovation in todays. Although most companies had previous good plans, but those are not satisfied. Because of failed to change management and continued next activity. Many Project for Process innovation are ended as disposal project in my case, if they want next project, they need a new plan which needs additional fund and resource. This paper studied Process Innovation and Six Sigma in many things and proposed new model for continued project on the master plan. Also it proposed next study subject about ERP Optimization and Harmonization after implemented ERP which is considered as next step of PI.

Motorola developed the framework of six sigma in 1987. In these days, many companies adapt this powerful tool. In 1996, six sigma was introduced to the Korean companies as a management innovation tool. This study shows case study of 'Champion Project' which was adopted on one Korean company. The champion project is directed by the leader who has a champion belt. The project focus on the processes optimization problem or resource concentration problem to solve critical issues inside of the process. This case study shows the result of champion project. The effect was encouraging in the aspect of effectiveness and efficiency. The most important point of this study is an introduction of the third generation six sigma which was successively adopted on the Korean company.

Foodservice industry serves enormous volumes of food each day, yet they rely on what might be the most poorly educated, most transient, and youngest work force in the whole food industry. These individuals handle every meal or item which is served. It is a situation ripe for problems, problems which are all too real. HACCP system is a preventive approach stages where loss of control could present a food safety risk in a food service operation. But it is very difficult to using HACCP Plan. The objective of this study was to develop a HACCP Plan using Six Sigma Methodology. This new HACCP Model from this study will be left to the each operation to develop for themselves. This means that foodservice industry operations should modify new HACCP Model provided in this study to establish their own HACCP system for use in their own operations.
