Paste each section of your 8D, D1 to D8. The checker flags empty sections, a thin problem description, a root cause that stops at a person, training used as the only fix and a verification written as a plan. Each flag comes with an example of a better answer.
Nothing you type leaves your browser. Clearing or closing the page removes it.
What it checks
| Section | What it flags |
|---|---|
| D1 Team | Only one name or role listed. |
| D2 Problem | No numbers, or too short to tell this problem from another. |
| D3 Containment | No counts or dates, or no result from the sort. |
| D4 Root cause | Blames a person, or does not say why the defect escaped. Words like mistake proofing do not count as blame, and a person named with a process cause after "because" does not either. |
| D5 Corrective action | Training, talks or reminders as the only action, sorting passed off as a fix, or no due date. |
| D6 Verification | Written as a plan or still pending, or no evidence of the result. |
| D7 Prevent recurrence | Training or a talk alone, or no documents or similar processes named. |
| D8 Close | Empty, or no close date. |
Worked example
The example is a made up 8D with the usual problems. The problem is "Bracket parts were bad," the containment is "Inspected stock," and the root cause is "Operator error." The fix is "Retrain the operator," the verification is "Will check next month," and the last section is empty.
The checker passes only the team. It flags the problem and containment for having no numbers, the root cause for stopping at the person, and the corrective action and prevent recurrence for relying on training. It flags the verification as a plan, and marks D8 as missing.
Why these weak spots
These are the points where customers and auditors push an 8D back. A root cause that stops at a person invites the same defect next quarter. A fix that depends on memory fades. Read how to write each section in how to write an 8D.
The checker reads the words you wrote. It cannot tell if the content is true. If your customer has its own 8D format or rules, follow those first. This is a screening check, not a review.
