Find what happened. Prove what follows.

Connect the event to the batch, sample and original evidence. Ask neil to investigate the history, test competing explanations and prepare the next controlled change.

7 minutes beyond the permitted hold

The hold ran seven minutes over.

Mixing ended at 10:12. Transfer completed at 11:04. The 45-minute limit ended at 10:57. The delay is recorded; cause and batch impact remain open.

Preserve the event before explaining it.

DEV-018 concerns a 52-minute post-mix hold against a 45-minute limit. The deviation links batch B-041 and sample IPC-041. That establishes the departure from the procedure—not the reason for the delay or its effect on the batch.

Record containment separately: what was restricted, who acted, when, and what must be checked before the restriction changes. An immediate correction does not replace the original observation or close the investigation.

Inspect DEV-018 in the native interface

Test explanations against the evidence.

Start with the transfer handoff, the complete temperature history and applicable hold-time evidence. The three recorded temperatures are within 2–8 °C, but they do not establish continuous coverage. The 10:16 sample predates the overrun; it cannot describe the later condition by itself.

Retain competing explanations, supporting and contradicting observations, and what would distinguish them. If the evidence is inconclusive, record the uncertainty and next controls. A required root-cause field is not a reason to invent a conclusion.

Ask neil to do the investigation work.

neil can assemble permitted process, sample, equipment and quality records into a source-backed assessment. Ask for the missing evidence, the work to obtain it and the configuration needed to prevent the same gap on the next batch.

Reconstruct the batch chronology
Reconstruct DEV-018 from the batch, handoff and sample records. Keep source times and identify gaps before proposing an explanation.

neil can assemble attributable events and link each observation to its source. Ask it to create evidence requests for incomplete temperature history, transfer handoff and hold-time support, without replacing missing data with a narrative.

Compare competing explanations
Compare plausible reasons for the extended hold with prior deviations. Show evidence for, evidence against and what would distinguish them.

neil can compare permitted process, equipment and quality records, rank candidate explanations and prepare a linked investigation plan. A recurring pattern is a question to test, not an established mechanism or product-impact decision.

Configure the control and its verification
Prepare a change to the hold-and-transfer workflow, with source-time capture, escalation and tests for missing or late events.

neil can author proposed fields, workflow states and verification cases, then assemble the change and training-impact work for review. Ask it to define the source population and recurrence measure for effectiveness follow-up. Authorised people verify and publish the change.

Start with your investigation workflow

Illustrative requests and proposed work, not a demonstrated neil execution. People assess the evidence, verify configuration and approve decisions.

Verify the action after the work is done.

Product disposition, investigation closure and action effectiveness are different decisions. Preserve the evidence and authority for each. A procedure revision or completed training task shows implementation; it does not establish that recurrence has changed.

Compare a defined event population and its operating exposure before and after a change. Keep the time window, exclusions and unresolved evidence with the review. When a criterion is not met, create the follow-up and retain the earlier conclusion.

Questions and answers

It manages deviation detection, contemporaneous capture, containment, classification, chronology, contextual evidence, affected-population assessment, investigation plans, hypotheses, root cause, recurrence, product and data decisions, CAPAs, extensions, effectiveness, trends, approval and closure.
Configured and verified automations can create or propose deviations from connected events, retaining the recorded values and source references. The source integration, trigger and exception handling must be defined for your workflow. Authorised users assess classification and operational meaning.
Keep the observed action separate from the explanation for it. Use the investigation plan to assess task design, procedure, interface, tools, workload and other relevant conditions. Record supporting and contradicting evidence; a ‘human error’ label alone does not explain the mechanism.
Approved trace rules follow material, process, equipment-use, room, sample, result, data and inventory relationships backward and forward. Potentially affected, assessed unaffected, confirmed affected and unknown states remain distinct.
Yes. The record retains tested hypotheses, available and missing evidence, uncertainty, residual risk, interim controls, product decision, additional monitoring and approval rather than forcing an unsupported root cause.
Similarity can use failure mode, process, equipment, material, method, shift, site, supplier, cause, context and time. Proposed matches remain reviewable, and patterns link to exact prior events and actions.
Each extension retains the original date, reason, progress, remaining work, current product or data state, risk, interim controls, new date, history, approvals and escalation. Repeated extensions remain visible.
Approved causes and residual risks create actions tied to the expected outcome. CAPA, engineering, document, training, supplier, validation or change records retain the source deviation and return implementation and effectiveness evidence.
Configured gates require approved impact, cause or inconclusive rationale, product and data decisions, corrections, linked actions, commitments, extension status, effectiveness plan, required communications, signatures and no unresolved mandatory branch.
Follow one representative event from its original evidence through investigation and the required decisions. Test missing sources, an inconclusive result, an extension and an attempted premature closure. Verify linked action and change workflows, including what happens when an effectiveness criterion is not met.
