TapRooT is a method your organisation adopts and gets trained in. DatumKeep is a system that runs the investigation and remembers it — so the next one starts from what the last one found, rather than from a blank page.
You want a formal, widely recognised investigation methodology with established training and certification — particularly for safety-critical incident investigation — and you already have a working way to store and find past reports.
Your problem is less "how do we investigate" and more "why do we keep re-investigating the same failure". You want the analysis guided, the evidence cited, your own resolved cases surfaced automatically and SPC in the same system.
TapRooT is a long-established root cause analysis methodology with supporting software and training, widely used for incident and safety investigations. Its strength is a disciplined, repeatable investigation process built over decades of practice.
DatumKeep is a quality intelligence platform for manufacturing: AI-guided RCA with 5-Why, Ishikawa and 8D, SPC, CAPA and a knowledge engine built from your own resolved cases. This page compares it against TapRooT as an investigation methodology and its supporting software. It is not a comparison of training programmes — we do not offer one.
Side by side
Read the chips, not the sentences. We start with the rows where TapRooT is the better answer.
| What | TapRooT | DatumKeep |
|---|---|---|
| Where TapRooT is stronger | ||
| Track record | Yes Decades of investigations across safety-critical industries. | No Early stage. First plants onboarding now. |
| Training and certification | Yes Established courses and a recognised practitioner credential. | No None. The product guides the method; it does not teach a syllabus. |
| Safety and regulatory investigation | Yes Long-standing fit for incident and safety casework. | Partly Audit-ready analyses, but built for manufacturing quality. |
| Where both do the job | ||
| Structured investigation | Yes A disciplined, repeatable process applied by trained analysts. | Yes 5-Why, Ishikawa and 8D, with steps that unlock as evidence exists. |
| No blame | Yes Systemic causes over individual fault, as a founding principle. | Yes Enforced in the output: process causes, never a named person. |
| Where DatumKeep is different | ||
| Your past cases resurface | Not the focus Reuse depends on how you store and find past reports. | Yes Similar resolved cases surface in context, before you start. |
| SPC evidence in the analysis | Not the focus Investigation-first; process statistics sit elsewhere. | Yes Control charts, capability with intervals and Gage R&R, same system. |
| AI in the loop | Not the focus The analyst drives every step of the method. | Yes Drafts hypotheses and cites evidence; a human signs off. |
| A gate before the report | Not the focus Rigour comes from applying the method correctly. | Yes The report cannot be produced below the evidence floor. |
| Did the fix hold? | Not the focus Improvement comes from training and consistent practice. | Off by default Solutions scored by whether the failure actually came back. |
| One system for RCA, CAPA and SPC | Partly Investigation-centred, with supporting software. | Yes One core; evidence flows between the modules. |
// Off by default means shipped and enabled per workspace by an admin, not roadmap. Not the focus is not a defect — it means the capability sits outside that product's centre of gravity, as its own positioning describes it. Competitor rows are based on publicly available information; capabilities evolve on both sides, so verify details with each vendor.
What is mechanical, not methodological
A methodology argument is easy to make and hard to check. These are the parts of an investigation that happen the same way every time, whether or not anyone is watching — which is the only kind of rigour a buyer can verify in a demo.
- 5-Why, Ishikawa (6M) and 8D, each a guided sequence rather than a blank template
- Steps unlock when their evidence exists, not when someone clicks past them
- An evidence floor the report cannot be produced below
- Every finding carries a citation to the evidence it came from
- Similar resolved cases retrieved from your own history at the start of an analysis
- Eight documented states where the product declines to answer, each naming its threshold
- Systemic framing enforced in the output — no individual is ever named as a cause
- An audit-ready PDF per analysis, carrying its traceability chain
- CAPA tracked to closure, with a named human approver on sign-off
- SPC evidence available inside the analysis: charts, capability intervals, Gage R&R
// Live today. The one item in the table above marked off by default — scoring whether a fix held — is shipped and enabled per workspace by an admin.
