Keep your technicians' and veteran employees' knowledge in the company before they retire

What experienced people know goes beyond the written steps. It shows in the moment they stop to listen to a machine, ask one more question, or realize a case doesn't match the manual. Our job is to capture that reasoning before it's gone.

Keep your technicians' and veteran employees' knowledge in the company before they retire
The short version
  • A company's most valuable knowledge often sits in the heads of a few people, and it walks out the door with them the day they leave.
  • Don't start by asking them to write a manual. Start by recording them while they solve real problems, which gives you something far more usable.
  • A good system always answers with its sources, so people can check which document an answer came from.

Start with knowledge that is at risk and that people actually call on

Ask yourself: if the technician who has been with you for twenty years resigned tomorrow, which work would stall immediately? That answer is your list of knowledge to capture first. Writing manuals for the entire factory can wait.

Build a Knowledge Risk Map from four questions. If this person weren't here, which work would stop? How much damage would a mistake cause? How long does it take to teach? How many people could back them up? Then rank the situations, such as errors that keep calling the senior technician back, machine setup when the raw material changes, exceptions for major customers, or steps that affect safety.

Don't ask experts in broad terms what they'd like to pass on. Pick a real incident and do a walk-through: what signal did they see, which causes did they consider, in what order did they check, when did they have to stop, and where do newcomers usually go wrong? Record the reasoning and the conditions as well as the normal steps.

The goal: shorten the path from “I don't know who to ask” to “I got advice that fits the context, and I know when to escalate”.

Turn experience into knowledge cards

A better approach than asking them to write a manual is to shadow them while they solve real problems, and record what they look at first, what they base their decisions on, and which cases they've seen where the method doesn't work.

Inspection stepsOrder, reasoning, reference values and images

LifecycleOwner, version, review date, status

AI can transcribe, structure and draft, but an expert has to check the meaning before anything is published. Break content into small pieces that each answer one problem and link to the full manual. Use Draft, Approved and Deprecated clearly, and never let old documents rank as high in search as the current version.

Store the right media: video suits movements and positions, photos suit symptoms, and documents suit rules. Every piece needs metadata, though, or AI may pull an answer for the wrong model.

Design an assistant that cites its sources and can say it doesn't know

The system should ask for context before searching, such as the machine model, error code, customer or what has already been tried. Answers have to show the source, version and date, and keep what is confirmed apart from what is only a suggestion. If the evidence isn't enough, it should say nothing was found and open an escalation path. It must never make up safety procedures from general knowledge.

Limit access by role, site and confidentiality level. Log questions, the sources used and feedback in line with your privacy policy. Don't automatically feed every chat message back into the knowledge base, because misunderstandings will multiply. Let AI draft updates and have the owner approve them.

A test set before going live

  • Normal questions, phrased in many different ways
  • Models or conditions that look similar but need different methods
  • Questions with no answer, where the system has to stop
  • Data the user isn't permitted to see
  • Old content that must never be recommended

Keep the knowledge base fresh and producing results

Tie updates to routine work: when an important work order or incident is closed, AI drafts a knowledge card from the evidence, and an expert reviews it before it's published. A dashboard shows unanswered questions, overridden answers, content close to expiry and articles nobody uses, which together make up a quality backlog.

Every time someone corrects an answer or closes a job, the system feeds it back into the library so it stays fresh

Measure Time-to-Answer, First-time Fix, Repeat Incidents, Escalations, onboarding time and Safety Errors together. High adoption isn't enough if the answers are wrong. Start with 20 problems and one shift team, and expand categories and languages once the results are good.

Success comes from building a loop in which experts get credit, new employees learn quickly and the organization updates its lessons after every real incident. Simply extracting knowledge from people won't get you there. Built this way, the system becomes an organizational memory with someone accountable for it, instead of one more file store.

Use a decision replay instead of asking “Is there anything you'd like to teach?”

Take a recent incident, open the photos or the work order, and have the expert walk through it point by point: what they saw, which options they ruled out and which signal changed their mind. Asking “Where would a newcomer go wrong?” usually draws out more tacit knowledge than asking them to write a manual from a blank page.

The most critical knowledge often sits with a single person, and leaves with them if nobody captures it

Hypothetical case: A senior technician is about to retire. The manual only says to check the valves in order, but the replay reveals that he listens to the sound before opening the cover, to rule out a pressure problem. So the team adds audio clips, examples of abnormal sounds and safety-stop points to the knowledge card. New employees now understand why each step matters, along with what the steps are.

The 3C rule for answers

Context: which machine or customer it applies to. Citation: the source and the version. Cut-off: where to stop and hand over to a specialist. If any one of the three is missing, the answer isn't ready for use on the floor.

Tip: Credit the person who shared the knowledge and the reviewer by name on each knowledge card. Showing that you value your experts turns sharing into a matter of professional legacy, so it doesn't feel like their knowledge is being taken in order to replace them.

DNA MAKER · SOLUTION BLUEPRINT

From knowledge to a problem-solving system that works in practice

The underlying problem

A good knowledge system answers from approved sources, states the context and knows when to stop, even if that leaves some questions unanswered.

A step-by-step approach

  1. Build a Knowledge Risk Map and collect decision replays from real incidents
  2. Turn them into knowledge cards with context, citation, cut-off and an owner
  3. Build a retrieval-based assistant with permissions, feedback and a review cycle

Let your organization's knowledge answer questions while staying clear about who owns the truth

A valuable knowledge base has to be more than a document search box. DNA Maker starts by helping the organization choose the questions that matter, and by setting up the taxonomy, metadata, owners, versions and escalation points. The client's experts certify the content, and we help design the capture and retrieval methods so answers show their context and sources. Users don't have to trust AI blindly, and the organization can see which questions still have no knowledge behind them.

DNA Maker can build a knowledge portal, enterprise search or a RAG-based AI agent on web or mobile, connected to SOPs, manuals, tickets and internal media. It controls access by role, answers with citations, collects feedback and hands over to an expert when the information isn't enough. We help all the way from the knowledge workshop, conversation UX, data preparation and system architecture through development to evaluation and analytics. If your organization has plenty of files but employees still keep asking the same people the same questions, we're ready to help turn that knowledge into a system that is easy to search, trustworthy and maintainable.

Software engineering glossary

This table is a shared vocabulary for executives, process owners and the development team, so nobody reads a term differently. There's no need to memorize it. Read the meaning, the example and the question on the right, because those questions often reveal scope, risks and hidden costs before development begins.

TermWhat it isA simple exampleWhat to ask the development team
RAGHaving AI search the organization's own data before it answersAnswering from an approved SOP, with a link to the documentWhich sources does the system search, and how does it keep old documents out?
