An 8D report is often judged on its first page. If the problem statement is vague or the containment count does not add up, the customer sends it back before anyone reads the root cause. A good 8D problem solving template forces the facts in early: a sharp is/is-not, a counted suspect quantity, two proven causes and a prevention step that reaches past one part. Watch AI draft the first disciplines from real complaint data in a short 8D workflow demo.
Run Every 8D From Complaint to Closure With the Evidence Already Drafted
iFactory 8D Workflow guides the team through D1 to D8 in order. AI drafts the problem description and the is/is-not from complaint, traceability and process data, and the customer-ready 8D exports in one click.
D0 to D8: The Question Each Discipline Must Answer
The 8D method came out of Ford, where the Team Oriented Problem Solving manual was first published in 1987. Ford's Global 8D revision in the late 1990s added D0 for preparation and emergency response. The format now reaches well beyond Ford: VDA published its own 8D volume in November 2018, and aero-engine suppliers work to SAE AS13000, which uses the same eight disciplines. The matrix shows where AI can help and where the team still decides. Ask our CAPA support team how your customers' forms map to it.
Is/Is-Not Draws the Line Before Anyone Guesses a Cause
A problem statement such as "latch broken" sends a team in every direction. The is/is-not method compares where the defect appears with where it could appear but does not, and the difference points to what changed. Take complaint C-2291, an illustration: a harness maker found 37 connector housings with an incomplete locking latch in a shipment of 9,600 from an eight-cavity mould. Let AI fill the first draft from your own traceability in a guided D2 session.
Only cavity 6 changed during the tool maintenance on 13 Oct. Whatever changed there is the first candidate, and it must be proven, not assumed.
Count the Suspect Parts in Every Location Before You Sort
Containment protects the customer while the cause is still unknown, so the scope has to be counted, not estimated. For C-2291, every cavity-6 part moulded from 13 Oct until the tool was pulled on 20 Oct is suspect: 2,400 parts across four locations. Some customers ask for every cavity to be held until D4 is proven, so check their rules before you narrow the scope. Set up containment records with our support team.
Ask for the Is/Is-Not and Get a Draft With Its Sources
iFactory reads the complaint, the cavity and date codes, the lot history and the tool records, then drafts D2 and the D3 suspect list for the team to check. Every line points back to the record it came from.
Two Causes, Each Proven by Switching It On and Off
Global 8D asks for the root cause and the escape point at D4: why the defect was made, and why the process did not catch it. A cause counts as proven only when you can make the problem come and go with it. Escape-point analysis deserves its own method, so the 8D record keeps it to a clear, tested line. Test a cause against your own data in a root cause walkthrough.
- Vent at the cavity-6 latch tip partly blocked after tool maintenance
- Trapped air stops the melt filling the thin latch section
- Proven: blocking the vent on a trial gave short shots, cleaning it stopped them
- Latch fill was not on the press audit checklist
- The press camera looked only at the mating face for flash
- Proven: seeded short-shot parts passed both checks
Verify the Fix on a Trial, Validate It in Production
D5 proves the chosen action removes the cause, usually on a controlled trial. D6 puts it into normal production and shows it keeps working, and only then does containment end. Running the two as one step is a common reason a customer asks for more evidence. Agree exit criteria for each customer with our support team.
D7 Reaches Past the Part to Similar Tools, Then the System
The prevention discipline asks what in the management system allowed the failure, and where else the same weakness sits. A fix limited to cavity 6 leaves every other multi-cavity tool exposed to the same missed vent. The four layers below are a practical way to scope D7. Review read-across candidates in a prevention planning session.
A Customer-Ready 8D Report You Can Copy
Customers rarely read an 8D from top to bottom. They check the header, the problem statement, the counts and the dates, then the proof. This layout puts those first and keeps each discipline to the evidence that answers it, shown here mid-investigation. Ask our support team for the same format with your customers' header fields.
Six Reasons an 8D Comes Back From the Customer
Supplier quality engineers see the same weak spots again and again. None of them needs a new tool, only discipline in the record. Check your last few reports against this list in a 30-minute review call.

The disciplines stay the same while the evidence changes by sector. These are illustrations, not customer case studies. Bring one of your open complaints to our quality support team.
Price the Hours Spent Gathering Evidence
Much of the effort in an 8D goes into finding data: lot histories, process changes, audit records and photos. That time can be measured. Every input below is assumed, so swap in your own figures. Run the numbers with us in a cost review call.
Faster containment and fewer returned reports may be worth more, but price them only from your own records.
8D Workflow and an AI Server That Arrive Ready
