Problem solving method

1.       The following statement with regards to 8D is correct, EXCEPT..  

• The eight disciplines (8D) model is a problem-solving approach typically employed by quality engineers or other professionals and is most used by the automotive industry but has also been successfully applied in healthcare, retail, finance, government, and manufacturing.

• The 8D process often uses input from customers (internal and external)

• The 8D is intended to be used as a “One Man Job” approach…not as a “Team” approach.

• The purpose of the 8D methodology is to identify, correct, and eliminate recurring problems, making it useful in product and process improvement.

2.       Choose the best practice on 5 Why Analysis

• Find the Occurrence cause is enough to conclude the root cause analysis

• Find the Systemic cause is enough to conclude the root cause analysis

• Find the Detection cause is enough to conclude the root cause analysis

• Detailed 5-Why analysis includes separate analysis paths for Occurrence, Detection &          Systemic root cause analysis is essential for root cause analysis.

3.       You received a detailed problem description from a customer on the issue related to your supply part.

How do you ensure the supply part to customer is secured during containment action?

• Supply the part as normal to customer because you think there is no issue with your part.

• Sorting/rework at customer on risk lot, recall/return risk lot in transit, sorting/rework part in production/warehouse, sorting/rework part at sub supplier.

• Stop production.

• Sorting/rework at customer only. No action on all the inventory at production/warehouse & supplier.

4.       What is the benefit of implementing 8D approach?

• Increased customer satisfaction and confidence in capabilities

• Better understanding of true root cause

• Root causes and results can be shared for future FMEA and problem prevention

• All of above

D1 = Define team ; D2 = Problem Description ; D3 = ... ; D8 = Congratulate Team

What is D3?

• Root Cause Analysis

• Containment/Immediate Action

• Corrective Action

• Preventive Action
