8D (8 Disciplines), also known as the 8-step problem-solving method, was originally a classic quality problem analysis technique used by Ford.
It is a very useful tool for solving problems in factories, especially when facing major defects.
It can establish a system that allows the entire team to share information and guide the team to provide problem-solving methods.
The original name of 8D is team oriented problem-solving steps.
The 8D team needs to be composed of individuals with product and process knowledge, who can manage time, and have authority and skills. A 8D team leader must be appointed.
An 8D that does not meet the above conditions is a failed 8D and cannot provide assistance when you need resources to solve problems.
If there is a quality abnormality in a system, it is not the failure of a single department's function, otherwise the entire system needs to be improved again
