What are the 8 steps of the 8D work method?

8D work method steps:

8D is the 8 basic guidelines for problem solving or 8 work steps, but in practice there are 9 steps:

D0: Signs of Emergency Response Measures

Purpose: The main purpose is to see if this type of problem needs to be solved with 8D, if the problem is too small or not suitable for the problem to be solved with 8D, such as price, funding and so on. For example, price, funding, etc. This step is for emergency response when the problem occurs.

Key point: Determine the type, size, and scope of the problem. Unlike D3, which is a temporary response to the product or service problem itself, D0 is a response to the problem as it occurs.

D1: Team Formation

Purpose: To form a team whose members have process/product knowledge, are allotted time and granted authority, and have the technical qualities required to solve problems and implement corrective actions. The team must have a mentor and team leader.

Key Points: membership, knowledge of process, product; objectives; division of labor; procedures; team building

D2: Problem Statement

Purpose: To detail in quantitative terms the internal/external customer complaints related to the problem, such as what, where, when, extent, frequency, etc.

"What went wrong with what"

Methods:Quality Risk Assessment, FMEA analysis

Key points:

1. Collect and organize all relevant data to describe the problem

2. The problem statement is a particularly useful data for the problem being described summary of the problem

3, Review existing data to identify the problem and determine scope

4, Subdivide the problem to break down the complex problem into individual issues

5, Problem definition to find a description that is consistent with the problem identified by the customer, "what's going wrong with what" and the cause of the unknown risk grade.

D3: Implement and Validate Interim Measures

Purpose:To ensure that the problem is isolated from internal and external customers until permanent corrective action is implemented. (Originally the only optional step, but has evolved to be required today)

Methods:

Key Points:

1. Evaluate Emergency Response Measures

2. Identify and Select the Best "Temporary Suppression Measures"

3.

4. Implement and document

5. Validate (DOE, PPM analysis, control charts, etc.)

D4: Determine and Validate Root Causes

Purpose: To isolate the series of events, circumstances, or causes of the deviation referred to in the problem statement by listing, using a statistical tool, all the potential causes that can be used to explain the cause of the problem. determine the root cause of the problem.

Methods:

FMEA, PPM, DOE, control charts, 5why method

Key Points:

1. Evaluate each cause in the list of probable causes

2. Whether or not the cause can be made to eliminate the problem

3. Validate

4. Control plan

8D Method of Work

D5: Select and Validate Permanent Corrective Actions

Purpose:To test the program prior to production and review the program to determine that the corrective actions selected will solve the customer problem without adversely affecting other processes.

Method:FMEA

Key Points:

1. Revisit team membership

2. Decision making to select the best measure

3. Re-evaluate interim measures and re-select them if necessary

4. Validation

5. Management commitment to implement permanent corrective action

6, Control Plan

D6: Implementation of Permanent Corrective Measures

Purpose:To develop a plan for implementing permanent measures, identifying process control methods and incorporating them into the documentation to ensure that the root cause is eliminated. The long-term effects of the measure should be monitored as it is applied in production.

Methods:Fault prevention, statistical control

Key Points:

1. Revisit team members

2. Implement permanent corrective measures and abolish temporary measures

3. Use measurability of faults to confirm that faults have been eliminated

4. Control plan, process document modifications

D7: Preventing Recurrence Occurrence

Purpose: Modify existing management systems, operating systems, work practices, designs, and procedures to prevent the recurrence of this problem and all similar problems.

Key Points:

1. Select Preventive Measures

2. Verify Effectiveness

3. Make Decisions

4. Redefine the Organization, Personnel, Equipment, Environment, Materials, and Documents

D8: Group Congratulation

Purpose:To recognize the collective efforts of the group, summarize and congratulate the group for its work.

Key points:

1. Selective retention of important documents

2. Streaming of the group's work and documentation of the insights

3. Understanding of the group's collective strength in solving the problem and its contribution to solving the problem

4. Necessary material and spiritual rewards.

8D, also known as the team-oriented problem-solving approach, 8D Problem Solving (8D Problem Solving) is one of Ford's ways to deal with the problem, but also applies to the process capability index is lower than it should be the value of the problem, which provides a set of logical problem-solving methods, at the same time, for the statistical control of the process and the actual quality enhancement of the bridge between the bridge. It provides a set of logical problem-solving methods and builds a bridge between statistical process control and actual quality improvement.

During World War II, the U.S. government took the lead in adopting a process similar to 8D - "Military Standard 1520," also known as the "Nonconforming Corrective Action and Deployment System. ". In 1987, Ford Motor Company first documented 8D in writing, naming it Team Oriented Problem Solving in one of its course manuals. At the time, Ford's powertrain division was struggling with a number of recurring production problems over the years, so its management asked Ford to provide an instructional program to help solve the problems.

8D is a problem-solving method used primarily in the automotive and similar processing industries. It was originally developed by Ford as a special requirement for globalized quality control and improvement, and has since become a special requirement for QS9000/ISO TS16949, Ford's.

The 8Ds are used primarily in the automotive and similar processing industries.
