4. What are 8-D’s & 5-Why’s?
(Fundamentals to good problem solving)
Both the 8-D (Eight Disciplines) and 5-Why’s are
methodologies for structured problem solving.
8-D was developed by Ford in the mid 80’s.
5-Why was made popular in the 70’s by the introduction of
the Toyota Production System .
8-D’s and 5-Why’s are normally prepared in these
instances;
1. To document the resolution of a problem.
2. To communicate resolution status to the customer.
Most suppliers use one or the other formats across all other
products and customer groups.

6. What is the 5 Why Process?
The 5 Why process is simply a problem-solving technique to
help in getting to the root of the problem quickly.
Key Benefit: It’s easy to learn and apply.
The 5 Why strategy involves looking at any problem and
asking: “Why?” to “What caused this problem?”
The answer to the first “why” will prompt another “why”,
and the answer to the second “why” will prompt another
and so on; hence the name 5 Why.
Each “Why” should be clearly linked to each other.
Solutions come from the 4th, 5th, or even 6th why.
How do you ask “Why”
