AI root cause investigation software that works with your existing QMS
QLogix Root cause investigation is AI-enabled root cause analysis software for GMP manufacturers, sold on its own for organizations that already keep their deviations and CAPAs in another QMS. It takes a deviation, OOS or OOT result, complaint or audit finding from the first write-up to an approved, tested root cause and a corrective and preventive action plan. From the write-up and the attached SOPs, batch records and lab records, the AI drafts the problem statement with IS / IS NOT, the containment, 5 Whys chains, a fishbone and the CAPA plan, and every quote names its source. The investigator tests each fishbone cause as a hypothesis and dispositions it, and the conclusion is judged against eleven robustness checks before the record can be routed for signature. Each accepted action records the CAPA number it was raised under in your QMS, and the approved report goes back to the event there as a locked PDF.
What the product does
- Investigations of deviations (numbered in the DEV series), OOS or OOT results, complaints, audit or inspection findings and other events, opened from a write-up with the SOP, batch record, lab record, equipment or maintenance log, training record, specification or previous investigation attached.
- Each attached document fingerprinted (SHA-256) and numbered D1, D2…; every quote in the analysis names the write-up or the document it comes from, and a withdrawn document stays on the record with the reason.
- An AI-drafted root cause analysis in seven steps: the problem statement with IS / IS NOT for what, where, when and extent; containment with product and patient impact, other batches and the regulatory assessment; 5 Whys chains with each step marked Evidence or Assumption; a fishbone across six categories; the root cause; the conclusion; and the CAPA plan.
- Every fishbone cause written as a testable hypothesis with a test method and what would support or refute it; the investigator records the result found, the evidence and the outcome, and the cause's disposition (root cause, contributing or ruled out) must agree with the outcome.
- Statistical tests on the data behind a cause: Welch, paired or one-sample t, Mann-Whitney, ANOVA, Fisher's exact or chi-square, with the p-value, effect size and confidence interval recomputed on the server when the test is saved to the record.
- A conclusion judged against eleven checks, among them every hypothesis tested, alternatives excluded, every IS and IS NOT explained, the cause verified and a system cause rather than human error, with a verdict of Robust, Adequate, Weak or Not established that sets how far the root cause confidence can go.
- A CAPA plan of corrections, corrective actions and preventive actions with owners, timing and effectiveness checks, each accepted or rejected by the investigator, who can add their own.
- Each accepted action records where it was raised in your own QMS (the system and the CAPA number); the reference is in the audit trail and on the report, and the panel Hand off to your QMS counts the actions raised.
- A locked PDF report of the approved investigation, with the source and write-up, the analysis, the hypothesis tests, the conclusion and each action with its QMS reference, to attach to the event in your QMS.
How it works beside your QMS
Nothing in the investigation depends on the rest of QLogix. Open it with the event's number in your QMS (the deviation, complaint or OOS number) and the write-up, run the investigation with the AI and the checks, raise the accepted actions as CAPAs in your QMS and record their numbers, then route the investigation for review and approval and attach the approved report to the event. Your QMS keeps the deviation and the CAPAs; QLogix keeps a signed, audited investigation with every quote sourced.
Licensed alone as the Root cause investigation suite (the investigations, document management for your SOPs and the regulatory library), or with CAPA management in the Agentic QMS, where the approved investigation opens a CAPA record prefilled with the root cause and the accepted actions.
How it fits the platform
Investigations open from wherever a problem is found. A complaint routed to investigation starts one with its text, summary and problem statement already written. An out-of-specification result in the LIMS opens an OOS investigation with the result, the determinations, the instruments, the standards and the analyst filled in, linked to the sample both ways, and the result is invalidated only on an assignable cause that investigation found. A CMMS work order that finds a failure opens a deviation investigation with the findings written, an out-of-tolerance calibration opens one with the impact assessment attached, and a deviation on an MES batch names the investigation that handles it.
Where people decide
The AI drafts the problem statement, the 5 Whys, the fishbone and the CAPA plan, reads each hypothesis result and can give a second opinion on the conclusion that changes nothing. The investigator tests each hypothesis, dispositions each cause with a reason, sets the root cause confidence, and accepts or rejects each action; reviewers and approvers sign the investigation with their password. The AI never dispositions a cause, accepts an action or signs.
Questions about Root cause investigation
What is root cause investigation software?
Software that takes a quality event from the first write-up to a root cause that is shown, not assumed: a problem statement, the possible causes, the evidence and tests that rule each in or out, and the actions that remove the cause. In QLogix the AI drafts the analysis from the write-up and your documents, quoting its sources; the investigator tests and decides, and the investigation is signed.
Can we use it with our existing QMS?
Yes, it is sold on its own for that. Enter the event's number from your QMS when you open the investigation, record the CAPA number each accepted action was raised under in your QMS, and attach the approved report (a locked PDF) to the event there. QLogix does not need to hold your deviations or CAPAs.
How does AI help with root cause analysis?
The AI drafts the problem statement with IS / IS NOT, the 5 Whys chains and a fishbone from the write-up and the attached documents, quoting the source of each statement. Each fishbone cause comes as a hypothesis with a test plan; the investigator runs the tests and decides. The AI can review the conclusion as a second opinion, but it changes nothing and never dispositions a cause or signs.
Does it handle OOS investigations?
Yes. An investigation can be of an OOS or OOT result. With the QLogix LIMS, an out-of-specification result opens one with the result, determinations, instruments, standards and analyst filled in, and the result is invalidated only when that investigation finds an assignable cause.
Does it support 21 CFR Part 11 electronic signatures?
It is built for them. Investigations are routed for review and approval with electronic signatures, and each signature asks for the signer's email and password again. Every AI draft, edit with its reason, decision and signature is an entry in a hash-chained audit trail, and the approved record is locked.
How is it licensed?
Per user per month, alone as the Root cause investigation suite or with other modules, ordered by purchase order from the client portal. There is no card payment or self-serve plan.
