All Ford parts must use 8D as a tool for quality improvement. Now some enterprises are not Ford suppliers or auto industry partners, and they also like to solve quality problems in this convenient and effective way, which has become a fixed and standardized problem-solving step.
1. Form a team: it is composed of relevant personnel of the subject, usually cross-functional, and explains the division of labor or responsibilities and roles among team members.
2. Describe the problem: express the problem as quantitatively and clearly as possible, and solve the medium and long-term problems, not just the immediate problems.
3. Implement and confirm temporary countermeasures (containment problem): Take immediate short-term measures to solve D2 to avoid the problem from expanding or worsening, including clearing inventory, shortening PM time and increasing manpower.
4. Find out the root cause: the real cause of D2 problem, and explain the application of analysis methods and tools (quality tools).
5. Select and confirm the formulated and verified corrective measures: formulate improvement plans, list possible solutions, select and implement long-term countermeasures, verify improvement measures, and eliminate the real causes of D4.
Usually, the long-term improvement countermeasures are explained step by step, and the Gantt chart of project planning or the application of quality method can be explained.
6. Correct the problem and confirm the effect: verify the result and effect after D5.
7. Prevention: Follow-up action plan to ensure that D4 problem will not happen again, such as personnel education and training, improving case sharing, standardizing operation and sharing knowledge and experience.
8. Congratulations to the team and plan the future direction: If the problem has been improved after the above steps are completed, we will definitely increase the team's efforts and plan the future improvement direction.
Extended data:
8D is also called team-oriented problem solving method. 8D problem solving method is used by Ford Company to solve problems, and it is also suitable for solving related problems when the process capability index is lower than its due value.
It provides a set of logical methods to solve problems, and at the same time builds a bridge between statistical process control and actual quality improvement.
During World War II, the US government took the lead in adopting a process similar to 8D-"Military Standard 1520", also known as "Corrective Action and Deployment System for Nonconforming Products". ?
1987, Ford motor company recorded the 8D method in writing for the first time, and named it "team-oriented problem solving" in one of its course manuals.
At that time, Ford's power system department was at a loss because of some production problems that appeared repeatedly for many years, so its management asked Ford Group to provide guidance courses to help solve the problems.
8D is mainly used to solve problems in automobile and similar processing industries. At first, it was a special necessary method for Ford to control and improve global quality, and later it has become a special requirement of QS9000/ ISO TS 16949 and Ford.
This method is suitable for solving all kinds of simple or complex problems that may be encountered;
The method of 1 and 8D is to establish a system for the whole team to enjoy information and strive to achieve the goal.
2, 8D itself does not provide a successful way to solve the problem, but it is a very useful tool to solve the problem; It is also suitable for solving related problems when the process capability index is lower than its due value; Provide solutions to customer complaints and major defects.
3, 8D method is a method used by American Ford Company to solve product quality problems. Widely used by suppliers, it has now become the best and effective method to solve product quality problems widely used by international automobile industry (especially automobile parts manufacturers).
