8D Root Cause Analysis (RCA) and 8D Corrective Action Process

The 8D Root Cause Analysis, as well as the 8D Corrective Action process, is a widely systematic approach in quality management, especially concerning 8D in quality control. This method includes eight comprehensive steps that are devised to problem solving by dealing with root causes of the problems comprehensively. The steps of the 8D process start with the formation of a team, a clear definition of the problem, and move on to interim containment actions. This is then followed by detailed root-cause analysis using the 8D RCA process, development and verification of permanent corrective actions, implementation, and recurrence preventing efforts. Encouraging details in the analysis: the 8D methodology steps encompass collaborative efforts and documentation that ensure durable solutions and continuous improvement in organizational processes.
Root Cause Analysis (RCA) is embedded within the 8D process and includes the following steps and techniques:

8d Problem Symptom

Problem Symptom is measured and transformed to “Object and Defect”

8d problem statement

Problem Symptom is reformed to Problem Statement using the 5W1H process

8d Pottential Causes

Potential Causes are gathered using the tools like Fishbone or Affinity Diagram

8d root cause

Problem Statement should fit using both the “is” and the “isn’t” sections of the question

8d root cause analysis

Root Cause concepts are developed from remaining possible causes on the tool and related changes from is/is not

8d Root Cause Verification

Compare theories with recent data and develop experiments for Root Cause Verification

8d root cause test

Test and confirm the Root Causes
