  1. 1. IntroductionSix sigma introduced in 1996 in KoreaKorea heavy industries & construction companyhave adopted six sigma as their managementstrategyIt will be referred to as Doosan from now onThe national Quality Prize for six sigma wasintroduced in Korea in 2000
  2. 2. Contd… Case study is about the improvement project at Doosan on the reduction of short shelf life material(SSLM) The DMAIC methodology was applied in the project The long-term vision of the company is to become a ‘competitive world-class company of 21st century with best quality & technology’ They made 4 strategies which were global company, best quality, best knowledge & competitiveness Case study presented is one of the CSTs which is contained in the Six Sigma Best practices
  3. 3. Background Doosan has been playing a major role in the development of korea’s national economy Doosan is the world’s top manufacturer of desalination plants with a boasted 25% international market share Doosan manufactures everything from base material to the finished product Doosan is busy strengthening its international competitiveness in the field of power generation
  4. 4. Contd… They are nuclear power plants, thermal power plants, turbines & generators, desalination plants, & castings & forgings Six Sigma in Doosan has 4 principles as follows: 1) Quality is our pride 2) Customers are our teachers 3) Innovation is our life 4) People are the most important asset
  5. 5. Doosan’s Six Sigma framework Doosan adopted TQC and TQM before as most other companies in Korea did Doosan now adopts Six Sigma as its major management strategy Doosan’s corporate framework of Six Sigma embodies the five elements : 1) Top-level management commitment 2) Stakeholder involvement 3) Training schemes 4) Project team activities 5) Measurement system
  6. 6. Top-level management commitment without a strongcommitment on the part of the top- level management, the training program andproject team activities are seldom successful. the role of top-level management asleaders, project sponsors and advocates is crucial. Doosan is a well-known company in its excellent top- level manage-ment commitment for Six Sigma
  7. 7. Stakeholder involvement• Stakeholder involvement means that the hearts and minds of employees, suppliers, customers, owners and even society should be involved in the improvement methodology of Six Sigma• The Six Sigma management is built to ensure this involvement through various practices, such as training courses, project team activities and evaluation of process performance.• Suppliers also need to be involved in a Six Sigma initiative.• It is also common for Six Sigma companies to help small suppliers financially in pursuing Six Sigma pro- grams
  8. 8. Contd…• Customers play key roles in a Six Sigma initiative• Customers should be involved in specific activities, such as identifying the critical-to-customer (CTC) characteristics of the products and processes• Having identified the CTC requirements, the customers are also asked to specify the desired value of the characteristic, that is the target value and the definition of a defect• This vital information is utilized in Six Sigma as a basis for measuring the performance of processes
  9. 9. Training scheme and project team activities Course levels Belts• Overall vision Champion• Most comprehensive MBB• Comprehensive BB• Median GB• Basic WB
  10. 10. Measurement system• Doosan provides a pragmatic system for measuring performance of processes using a sigma quality level, parts per million (PPM) or defects per million opportunities (DPMO)• There are two types of char-acteristics, continuous and discrete• Continuous characteristics may take any measured value on a continuous scale, which provides continuous data• From the mean and variance, the sigma levels and process capability indices can be calculated.
  11. 11. How to select project themes in Doosan? Company’s Management Goal Planning R&D Manufacturing Sales Other Division division division Division Division CTQs CTQs CTQs CTQs CTQs Sub-CTQs1 Sub- CTQs2 Process CTQ1 Process CTQ 2 (theme 1) (theme 2)
