The US Government standardized the process of Corrective Actions in MIL-STD-1520  (Corrective Action and Disposition of Nonconforming Material). This standard was first issued in 1974, and the last revision of the standard was Rec C, which was issued in 1986 and later was cancelled in 1995 without replacement.

This problem-solving approach was later formalized and popularized by Ford Motors.

8D or Eight Disciplines

The eight disciplines or the eight steps of the problem-solving approach. Later a step zero was also added to the approach. These eight steps (and initial step zero) include these:

D0 - Preparation and Emergency Response

D1 - Establish the Team

D2 - Describe the Problem

D3 - Interim Containment Plan

D4 - Root Cause Analysis

D5 - Develop Permanent Corrective Actions

D6 - Implement Permanent Corrective Actions

D7 - Prevent Future Recurrence

D8 - Recognize Contributions (Individual and Team)
