D0 (Prepare for 8D)
8DPreliminary step added to modern 8D methodology to assess whether emergency response is needed and if a full 8D is warranted. D0 addresses three key questions: Is immediate action required to protect customers? Is the problem significant enough to justify an 8D? Who should be on the team? Not part of original Ford 8D but widely adopted in automotive industry (IATF 16949). Separates crisis response from structured problem-solving.
