1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesAI can preserve laboratory know-how, but it cannot discover and validate that know-how on its own. The dependable approach is a socio-technical workflow: experienced scientists explain decisions and exceptions; AI transcribes, organizes and connects the evidence; subject-matter experts approve the result; and a permissioned retrieval-augmented generation (RAG) system answers questions only from those approved, versioned sources.
This matters because much of a laboratory’s practical expertise is absent from instrument files and formal SOPs. It lives in judgments such as whether a sample looks acceptable, which warning sign predicts a failed run, how a particular instrument behaves after maintenance, or when a documented range should be treated cautiously. A well-governed capture system can retain that context when staff change roles or retire without turning unverified anecdotes into operational instructions.

What tacit knowledge is—and why laboratories lose it
Tacit knowledge is practical understanding that people can use but have not fully written down. In a scientific laboratory it includes sensory cues, shortcuts learned through repeated work, contextual judgments, exception handling and the reasons behind a choice. An experienced scientist may know that a sample is likely to be compromised from a subtle appearance, that a particular instrument needs extra equilibration after a service visit, or that a nominally acceptable result should be investigated under a specific combination of conditions.

Raw instrument files record measurements. Neither necessarily records the reasoning that connects a real situation to a decision. Tacit knowledge is therefore most at risk during handoffs, rapid staff turnover, method transfers and retirement of senior researchers. If it remains in one person’s memory, a laboratory can lose not only a procedure but also the ability to recognize when the procedure does not fit the situation.

The OECD describes scientific theories as resting partly on tacit knowledge shared through scientists’ experience in physical, social and mental worlds. That observation explains why simply collecting more data does not solve the problem. A recording, database row or model output becomes useful only when the laboratory captures its context, confirms its meaning and preserves how it was derived.
Start with people, not a chatbot
Human elicitation is the first control point. AI can make conversations searchable and consistent, but it should not be asked to invent missing expertise or decide whether a scientist’s statement is safe to operationalize.
Interview experienced scientists
Use semi-structured interviews around a real workflow rather than asking, “What do you know?” Ask the scientist to walk through a recent run, a difficult sample, a failed experiment and a successful recovery. Probe for conditions, thresholds, sensory cues, exceptions, trade-offs and the point at which they would stop and escalate. Ask what they check that is not written in the SOP and why.

Observe work at the bench
Observation reveals actions that people omit when describing familiar tasks. With appropriate consent and access controls, record the sequence of setup, instrument checks, sample handling and cleanup. Note what the scientist looks at, touches or compares, while keeping patient, proprietary and unpublished information protected. Video can preserve spatial and procedural context, but it requires stricter privacy controls than a transcript alone.
Run debriefs and lessons-learned sessions
After a run, method transfer or incident, hold a structured debrief. Capture what was expected, what happened, which signal first indicated a problem, what decision was made, and what should be changed next time. Storytelling sessions and legacy talks can draw out the historical reasons behind local practices. The University of the Philippines Open University thesis Design, Development, and Testing of Tacit Knowledge-Capturing Protocol of PHilMech Scientists (Subaba, 2024) identified storytelling, lessons-learned sessions and legacy talks as effective approaches. Its pilot produced manuals, podcasts, videos and an online repository, and integrated the protocol into offboarding for retiring staff.

Include more than one expert
One scientist’s workaround may be a local preference, an obsolete habit or a response to an instrument that no longer exists. Bring at least two domain reviewers into approval, particularly where statements conflict. Their job is to reconcile differences, state the scope of a practice and mark unresolved disagreement rather than silently choosing one version.
A practical AI pipeline for turning experience into approved knowledge
The useful role for AI is controlled transformation. Preserve the original evidence, make each transformation inspectable and keep a human decision between extraction and publication.
- Record the source conversation or demonstration. Store the audio, video, date, participants and consent or access classification. Do not discard the raw source after transcription.
- Transcribe and timestamp it. Automatic speech recognition creates a searchable draft. A reviewer should correct terminology, instrument names, units and speaker attribution, especially where a transcription error could alter a procedure.
- Segment statements by function. Classify passages as instructions, prerequisites, conditions, acceptable ranges, exceptions, warning signs, failure modes, troubleshooting decisions, rationale or open questions. This is more useful than a single narrative summary.
- Attach context and identifiers. Link each statement to the person who made it, the instrument model, sample or specimen, method, laboratory site, date and related run or dataset. If a detail is unknown, record it as unknown rather than allowing the model to infer it.
- Draft a knowledge artifact. Generate a proposed SOP supplement, job aid, manual section, checklist or knowledge-graph record. Keep quotations or source passages available so a reviewer can verify the draft.
- Review and reconcile. Domain experts check technical accuracy, safety, scope, conflicts with current SOPs and whether the wording implies more certainty than the evidence supports. Two reviewers should approve high-consequence instructions.
- Publish a controlled version. Put the approved content in the laboratory’s document or knowledge system with an author, reviewers, effective date, superseded version and change history.
- Index only approved material for retrieval. A RAG assistant should search the controlled corpus, quote or link the relevant passages and show the version used to answer. Draft transcripts and rejected suggestions should not silently enter the operational index.
This sequence lets AI reduce clerical work while preserving accountability. It also makes correction possible: if a statement is later found to be wrong, the laboratory can identify the source recording, the published version and every answer generated from that version.
Use a controlled template for every knowledge item
Standardization depends on a shared vocabulary and a minimum set of fields. The 2024 Learning Health Systems paper by Wittner and colleagues argues that trustworthy reuse requires precise documentation of pre-analytical conditions, analytical procedures and data processing, with traceable, machine-actionable lineage for data and specimens. A laboratory can implement that principle with a template such as the following.
| Field | What to record | Why it matters |
|---|---|---|
| Claim or instruction | The action, observation or decision in clear language | Separates an operational rule from commentary |
| Context and scope | Site, workflow, method, sample type and situations where it applies | Prevents a local practice being treated as universal |
| Prerequisites and materials | Required training, reagents, consumables and instrument model | Shows what must be true before the step begins |
| Steps and conditions | Sequence, settings, timing, temperatures and acceptable ranges | Makes the instruction reproducible and machine-readable |
| Warning signs and troubleshooting | Observed symptoms, likely causes, checks and escalation points | Preserves the judgment usually omitted from SOPs |
| Evidence or source | Recording timestamp, document, run, sample, dataset or result | Allows an auditor to inspect the basis of the statement |
| Author and reviewers | Names or controlled identifiers, roles and approval status | Establishes accountability and expertise |
| Effective and superseded dates | When the item became valid and which version it replaces | Stops obsolete advice being reused |
| Linked entities | Samples, instruments, methods, datasets, deviations and results | Creates lineage from action to outcome |
The 2023 article Ten simple rules for managing laboratory information treats laboratory information broadly: experimental metadata, computational processes, inventories and equipment information all need to be transformed into useful scientific findings. A tacit-knowledge system should therefore connect narrative expertise to the same identifiers used by an electronic laboratory notebook (ELN), laboratory information management system (LIMS), instrument records and analysis pipelines.

How a laboratory chatbot should use its own protocols
Retrieval-augmented generation is a practical early use case. Instead of asking a language model to answer from general training data, the system retrieves relevant passages from the laboratory’s approved manuals, SOPs, job aids and guidelines, then generates an answer grounded in those passages.
What the assistant should return
- A direct answer limited to the retrieved, permission-appropriate material.
- Quoted or linked source passages, including document title and version.
- Important conditions, exceptions and uncertainty.
- A clear statement when no approved source answers the question.
- A correction or escalation route to a responsible expert.
What it should not do
- Promote an unreviewed transcript to an SOP.
- Merge conflicting versions without showing the conflict.
- Fill missing instrument settings, ranges or safety steps from model intuition.
- Expose documents, samples or patient information outside a user’s permissions.
- Present a plausible answer without provenance.
An ARUP Laboratories and University of Utah proof of concept assembled job aids, SOPs, multidisciplinary guidelines and classification systems, then used retrieval-augmented generation with locally run open-source language models. The authors reported preliminary ability to process and generate answers about sample handling, testing protocols and data interpretation. That is evidence of feasibility, not a general guarantee of accuracy or productivity. A local deployment can also reduce exposure of proprietary material, but it still needs access control, evaluation and maintenance.
Implementation sequence for a real laboratory
- Choose a high-value workflow. Start where handoffs, repeated training failures or retirement risk are visible: sample accessioning, a difficult assay, instrument troubleshooting or method transfer.
- Define the vocabulary and identifiers. Agree on names for sample types, instruments, methods, units, failure categories and approval states. Map them to existing ELN or LIMS identifiers rather than creating parallel labels.
- Capture exceptions deliberately. Ask experienced staff to describe borderline cases, sensory cues, “do not proceed” signals and recovery decisions, not just the happy path.
- Process with AI while retaining originals. Transcribe, segment and classify recordings, but keep immutable links to the raw files and timestamps.
- Use two-person technical review. Reconcile disagreements, test instructions against current equipment and mark assumptions or unresolved questions.
- Publish and version the artifact. Release the approved manual section, SOP supplement, checklist or knowledge-graph entry through the laboratory’s existing change-control process.
- Deploy permissioned retrieval. Index only approved artifacts, enforce least-privilege access and require source-linked answers. Locally run models may be appropriate where cloud transfer is unacceptable.
- Monitor and retire. Log unanswered questions, user corrections, citation failures, model drift and obsolete procedures. Feed confirmed corrections through review and retire superseded content rather than deleting its history.
Compare implementation options before choosing technology
| Approach | Capture richness | Standardization | Provenance | Privacy and deployment | Review burden |
|---|---|---|---|---|---|
| Form-only knowledge base | Low; depends on what the author remembers to type | Strong for required fields and controlled terms | Usually timestamps and authorship unless extended | Simple to host inside existing systems | Lower initial review, but omissions can be hard to detect |
| Interview, audio or video plus human editing | High; preserves stories, cues and exceptions | Moderate until converted into templates | Deep when recordings and timestamps are retained | Requires careful access control and storage decisions | High editorial and technical review |
| Ontology-backed knowledge graph | Depends on the capture method | High; relationships and controlled vocabularies are explicit | Can connect sample-to-result lineage | Integration and permissions are more complex | High upfront modeling and governance |
| RAG assistant over approved documents | Inherits the source corpus | Depends on document templates and indexing | Strong when citations and versions are shown | Cloud or local deployment; local models can limit data exposure | Continuous evaluation, correction and change management |
| Multimodal or autonomous conversion | Potentially very high, including video nuance | Still emerging; validation is difficult | Must be designed explicitly | Highest privacy and security complexity | Highest expert oversight requirement |
These options are not mutually exclusive. A laboratory can record an interview, produce a reviewed SOP supplement, represent key relationships in a graph and expose the approved documents through RAG. The critical design choice is not the model brand; it is where evidence is stored, who approves it and how a user can trace an answer back to its source.
Governance, privacy and quality controls
Protect sensitive material
Apply least-privilege access to recordings, transcripts, source documents and linked data. Patient information, proprietary methods, unpublished results and contractual restrictions may make a cloud service unsuitable. Separate identifying data from general procedural content where possible, encrypt storage and transmission, and define retention periods for recordings.
Make every answer auditable
Keep immutable source links, document versions, reviewer decisions and model or retrieval configuration. A user should be able to see which passage supported an answer and which version was active at the time. Microsoft Research’s CLeAR framework recommends documentation that is “Comparable, Legible, Actionable, and Robust”; those qualities support responsible use, evaluation and auditing of AI systems.
Quick wins for a faster PC:
Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Clear out junk files and repair common Windows errorsFree Scan →Measure the right failures
Evaluate whether the assistant retrieves the correct procedure, cites the correct version, respects permissions, distinguishes scope and refuses unsupported questions. Track corrections and near misses. Do not use fluent wording as a quality metric. A confident answer with an incorrect instrument setting is more dangerous than an explicit “not found.”
Define human accountability
Require expert sign-off before a tacit statement becomes an operational instruction. Assign owners for each method and a schedule or trigger for review after instrument changes, reagent changes, incidents or regulatory updates. Provide a visible route for staff to report a wrong answer, missing exception or obsolete document.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What is established and what is still emerging
Interviews, observation, debriefs, structured documentation, provenance, version control and human review are established practices for preserving expertise. The PHilMech protocol and the Taiho Pharmaceutical case study (2026) show how workshops and legacy sessions can turn senior researchers’ experience into standardized manuals and training material. Taiho describes knowledge-engineering workshops in which group discussion extracted experience for manuals, generative-AI chatbots and safety education.
Laboratory RAG assistants are demonstrated but early. The ARUP and University of Utah work is a proof of concept, and published examples remain largely case-study or feasibility level. Multimodal systems that infer procedural nuance from video, continuously updated knowledge graphs and autonomous conversion of expertise into validated SOPs remain emerging capabilities. The available literature does not establish a generalizable controlled statistic for productivity or reproducibility gains, so a laboratory should measure its own outcomes rather than claim a universal percentage.

The model invents a missing setting
Cause: retrieval found no authoritative value and generation filled the gap. Fix: configure abstention, require citations and route the question to an expert. Never promote the generated value into the knowledge base without evidence and approval.
Two experts disagree
Cause: the practice may differ by instrument, site, sample type or historical version. Fix: preserve both statements, identify their scope, test the difference where feasible and publish an explicit decision or unresolved status.
Users receive obsolete advice
Cause: indexing ignored effective dates or superseded versions. Fix: enforce version-aware retrieval, remove retired documents from the active index and retain their history for audit.
Free tools Windows power users keep installed
One-click scans. No signup required.
Staff stop contributing
Cause: capture feels like surveillance or adds work without benefit. Fix: explain access and retention rules, let scientists review their transcripts, credit contributors, schedule short sessions around real work and show how corrections improve the tools they use.
Preserving expertise when a senior researcher retires
Begin before the final handoff. Select the workflows for which the person is the escalation point, record demonstrations and failure stories, and ask what they would teach a successor on the first day and after the first failed run. Convert the material into reviewed job aids and SOP supplements while the expert is still available to answer questions. Link each artifact to the relevant instrument, method and historical examples, then expose it through a permissioned assistant only after approval.
A physical laboratory notebook remains useful for observations, deviations and troubleshooting context captured at the bench. It complements electronic laboratory records and provenance systems; it is not a substitute for controlled digital records, review or version history. The durable result is a chain from the scientist’s explanation to an approved artifact, from that artifact to a source-linked answer, and from every correction back to the responsible evidence.
