General Electric believes that a complete Six Sigma project implementation can be divided into five steps: it is defined, evaluated, improved, and controlled.
First, definition - is identifying the project process that needs to be improved, and determines the resources required for the project. 1. Determine the key issues of the project - What problems are most prone to project implementation? What is the importance of solving these issues to improve project quality? What is the cost of solving these problems? 2. Develop the specification of the project - describe the scope and objectives of problems, and also explain the division of labor, and the specific project process arrangements. 3. Define the process of the project process - the process steps involved in the project, and the starting and ending point of each process.
Second, the assessment - from the key internal factors that have a quality of the impact, evaluate the error rate of the identified quality factors. Specifically, it includes three aspects: one is to list the shortcomings in the project; the second is to collect the performance in the management process as a measure of the bottom line; third is to establish improvement goals. 4, choose quality characteristics - Who is customer, what is their key quality factor? What is the key quality factor in the project needs attention? 5. Define the assessment criteria - What is the standard acceptable for each critical quality factor? 6. Analysis of the evaluation system itself - Is the evaluation system you use? Is it reliable?
Third, the analysis-analyzes the data of the measurement stage, identify the main variables and secondary variables affecting the quality. Specifically include: 7, an assessment of current management quality conditions. 8. Setting the future management quality target. 9, which factors are affecting quality stability.
Fourth, improved - just improve the quality of action. Specifically include: 10, determine the main variables that affect quality management, and then measure their influence on quality. 11. Determine the acceptable variation range of important variables, which is the degree of change in the evaluation system to evaluate the main variable. 12. Finally, the link is adjusted to give it a quality improvement in an acceptable range.
V. Control - Use the monitoring tool to ensure that the adjustment production is adjusted, allowing the main variable to remain within the maximum adjustable range. Specifically include: 13, verifying the measurement system to ensure its application of new variables. 14. Determine the process capacity to ensure that the customer is fully recognized. 15. Implement process control to ensure that the control capabilities for new changes are true.
