Today we are going to learn about 8D and what does it mean!
8 steps to take to solve difficult, recurring, or critical problems (often customer failures or major cost drivers).
The structured approach provides transparency, drives a team approach, and increases the chance of solving the problem.
- D1: Create a Team: Gather a cross-functional team of about 5 people with product/process knowledge, and have them gather information and data related to the problem or symptom
- D2: Describe the Problem: Use the data and information to quantify and clarify the problem into a statement. Ask the 5W2H’s (who, what, where, when, why, how, and how many) for the problem.
- D3: Develop Containment Plan: Define and implement interim containment actions to isolate the problem from any customer in the future.
- D4: Determine and Verify Root Causes: Identify and verify all applicable causes and sources of variation that explain why the problem has occurred (special vs . common cause).
- D5: Verify Permanent Solutions: Collect data to confirm that the possible solutions will actually resolve the problem. Perform on a small-scale or “pilot” project first.
- D6: Define and Implement Corrective Actions: Discuss and review results, and develop a plan to implement the best solutions or countermeasures.
- D7: Prevention: Modify the management systems, operation systems, procedures, and practices to prevent recurrence of this and similar problems.
- D8: Congratulate the team: Formally thank team members for their involvement. Use approaches that appeal to each individual member, as not everyone wants to be rewarded the same way.
The following improvement tools are often used within the 8D methodology:
- Ishikawa diagrams (Cause and Effect diagrams, C&E diagrams or Fishbone diagrams)
- Pareto charts or Pareto diagrams
- 5 Why’s
- 5W and 2H (Who, What, Where, When, Why, How, How often)
- Statistical Process Control (SPC)
- Scatter plots or scatter diagrams
- Design of Experiments (DOE)
- Check sheets
- Histograms or Capability Analysis
- Failure Modes and Effects Analysis (FMEA)
- Flowcharts or Process Maps
