## Content

**Intro:** The 8D method gives a team a fixed path from a customer complaint to a verified fix: contain, find the cause, correct, prevent, close. This template lays out each discipline as a block you fill in, so the report reads the way automotive and industrial customers expect.

**Sections:**

#### How to fill in an 8D report

**Body:** Start with D1, naming a small cross functional team with a leader. D2 states the problem in measurable terms: what, where, when, how many, compared with what is normal. D3 protects the customer right away, with sorting, replacement or a tighter check, and records how long the containment runs. D4 separates the occurrence cause from the escape cause, since both need fixing. D5 and D6 choose and prove the permanent action with data. D7 spreads the learning to similar parts and documents. D8 closes the report and credits the team.

**Bullets:**

- Quantify the problem in D2.
- Show containment dates and quantities.
- Find both why it happened and why it escaped.
- Verify the fix with data before closing.

#### Choosing a root cause method

**Body:** The 8D format does not prescribe a tool. For a simple direct cause, 5 whys is enough. For many possible causes, use a fishbone diagram to list candidates and test each with data. For intermittent or complex problems, compare good and bad parts, and use is and is not analysis. Whatever you use, test the cause: if you remove it, does the defect go away, and if you reintroduce it, does it return? A cause that is only plausible is not a verified root cause.

#### Common mistakes

**Body:** Teams often jump from D2 to D5 and name operator error as the cause, which leads to retraining that rarely holds. Another mistake is leaving containment in place for months with no exit criteria. A third is closing at D6 without D7, so the same weakness remains in sister parts and processes. Customers also reject reports that give no dates, no owners or no evidence of effectiveness. Attach measurement data, updated control plan pages and the date containment ended.

**Cta:** If your 8Ds start from ERP quality notifications, we can help link the report to the lot, supplier and cost data automatically.

**Faq:**

#### What does D0 mean in an 8D report?

**Answer:** D0 is the preparation step used in some versions of 8D: recognise the symptom, plan the response and decide whether an emergency action is needed. Many forms fold it into D2 and D3 and start numbering at D1.

#### How fast must an 8D be completed?

**Answer:** Customers set the clock. A common pattern is containment within 24 hours, a root cause in about 10 days and full closure in 30 to 90 days. Check your customer specific requirements and quality agreement.

#### What is the difference between 8D and CAPA?

**Answer:** 8D is a team based problem solving format popular in automotive and industrial supply chains. CAPA is a broader quality system process in regulated industries. They overlap, and an 8D can serve as the record inside a CAPA.

#### Can I use this template for supplier problems?

**Answer:** Yes. Fill it as a record of your own response to a customer, or ask the supplier to complete it. For a formal request to a supplier, the supplier corrective action request template is a better fit.
