The 8D method: the problem stays solved.
The 8D method is the standard problem solving process for customer complaints, safety issues and problems that keep coming back: in steps D0 to D8 a team finds the root cause and makes sure the problem does not return. With SolveR your engineer goes through every step without guessing what comes next, and the customer gets the whole answer in one document.
When to use 8D, and when not to
A full 8D pays off when the problem is serious enough for a whole team and the customer expects an answer. For smaller problems it is too heavy, because the team spends more time on it than the problem needs. That is when you pick a lighter method.
- 4-Step for internal deviations such as scrap, rework and parts out of spec. The engineer closes the case alone, with no team and no forms.
- Just-Do-It for the obvious fix, done right away and written down at once.
- A3 when management needs to understand the problem: one page, from problem to actions.
One case, today and with SolveR
Demo case: a customer complains about dents on panel edges, 11 of 60 parts.
| Today | With SolveR |
|---|---|
| The complaint arrives by e-mail, with photos and measurements attached. | You enter the complaint once, and SolveR drafts the problem description: what it is and what it is not. |
| The engineer opens an empty template and asks colleagues whether they have solved this before. | As you describe the problem, similar solved cases from your knowledge base come up. |
| The cause is hunted down over several meetings, and the actions live in Excel. | The cause is confirmed, the actions are ones that already worked elsewhere, and the validation on 200 parts is on record. |
| The report for the customer is written at the end, and the case ends up in a folder. | The report is built from the recorded steps, and the case stays in the knowledge base. |
At the meeting we run it on your own data.
What you get
A finished 8D report that a customer or auditor can follow from start to finish. Every step is recorded and linked, from the first symptom to prevention, so nothing needs cleaning up before an audit.
Where SolveR guides you
SolveR walks your engineer through every step from D0 to D8, so nobody guesses the next step. It helps with the problem description through 5W2H and Is / Is Not, and with the cause through Ishikawa and 5 Why. It suggests causes and actions from your plant's closed cases, and the engineer decides.

One knowledge base
A closed 8D stays in the knowledge base with its causes and actions, even after the people who solved it have moved on. The next time someone describes a similar problem, SolveR shows that case and what worked back then, so the next engineer starts from what the plant already knows. Every method writes into the same base. What one case teaches applies to all of them.
Numbers from a pilot on 8D cases
The numbers come from a pilot on real 8D cases. We timed the first with a stopwatch in steps D2 and D4, calculated the second from an hours model for a full 8D, and the third holds by design of the knowledge base.

Questions about the 8D method
When do you need a full 8D, and when is a shorter method enough?
You need a full 8D for a customer complaint, a safety issue or a problem that keeps coming back, and above all when the customer asks for an 8D report. IATF 16949 requires suppliers to have a documented problem solving process, and automotive customers often prescribe 8D for it. For an internal deviation with no customer involved, 4-Step is enough, and for an obvious fault, Just-Do-It.
How is 8D different from a 4D report or 4-Step?
A 4D report is a shortened form of 8D for manageable problems, and its four steps vary from company to company. 4-Step in SolveR is for internal deviations: the engineer closes the case alone, with no team and no forms. 8D adds the team, immediate actions to protect the customer, validation of the actions and prevention.
What does the customer or auditor receive?
One 8D report in which every step from the first response to closure is recorded and linked: the problem description, immediate actions, the confirmed root cause, corrective actions with proof that they work, and prevention. An auditor can follow it from start to finish, so nothing has to be fixed before the audit.
Can we bring our old 8D reports into SolveR?
Yes. At onboarding we bring your 8D and FMEA archive into the knowledge base, so a new case starts from what your plant has already solved.
Who decides, the engineer or the AI?
The engineer decides. SolveR suggests causes and actions from your plant's closed cases and shows the source of each one: a document, a measurement or an earlier case. The engineer checks every suggestion and accepts or rejects it.
Other methods
Every team picks the method that fits the problem, and one knowledge base stands behind all of them.
