The Invisible Risk: When Expertise Walks Out the Door

In industrial maintenance, seconds determine hours. A quickly identified fault, a precise diagnosis, a proven solution strategy: these make the difference between a brief intervention and half a shift of downtime. But what happens when the knowledge that enables these fast decisions is not stored in a system, but in the head of a single person?

This question affects every manufacturing company today. And the answer is uncomfortable in most cases.

The Silent Threat: Knowledge That Leaves

Experienced maintenance technicians carry years of know-how with them: what a specific error code on a specific machine actually means, which measure worked last time, which component is the critical bottleneck, and how an emerging fault announces itself hours before the breakdown. This knowledge is real, valuable, and completely unsecured.

Studies show that on average 42 percent of the skills and knowledge an employee applies in their role are known only to them and cannot be immediately replaced by a successor. In a maintenance environment, where experience is often the decisive diagnostic tool, this loss carries exceptional weight.

That sounds abstract. The concrete consequences are anything but.

What Knowledge Loss Really Costs

Every minute a technician spends searching for information is a minute they are not solving a fault. A McKinsey study found that employees spend an average of 1.8 hours per day searching for and compiling information. That is almost one full working day per week.

For a maintenance operation, this means: manuals nobody can find. Incidents that cannot be looked up because they were never properly documented. Colleagues who have to be called, even though the answer is somewhere in the system.

Estimates suggest that a company with 30,000 employees can lose 72 million US dollars annually in productivity, solely through day-to-day inefficiencies caused by knowledge loss.

And the costs of unplanned downtime add to that. According to the report "The True Costs of Downtime 2023", unplanned stoppages now cost Fortune Global 500 companies around 11 percent of their annual revenue.

Three Forms of Knowledge That Matter in Maintenance

To understand why structured knowledge management is so important, it is worth looking at the different types of knowledge technicians rely on every day.

Documented Technical Knowledge
Manuals, circuit diagrams, inspection protocols, manufacturer specifications. Present in every operation, but rarely structured and accessible. In some facilities they sit in a cabinet, as a PDF on a network drive, or get shared via WhatsApp.

Historical Experience
Which measure worked last time? Which error codes are typical for a specific machine? What helped with similar symptoms? This information is generated with every completed fault. Without capture, it is lost.

Implicit Expert Knowledge
What the experienced technician knows without ever having written it down. The anomaly they recognize by sound. The sequence they execute intuitively. This knowledge is the most valuable, and the hardest to secure.

All three forms must be systematically captured, connected, and made accessible for maintenance teams to truly operate at full strength.

The Problem of Knowledge Silos: Knowledge That Does Not Flow

In many companies, islands of knowledge exist. The technician in Plant A knows how to fix a recurring fault on a specific machine. Their colleague in Plant B faces the same problem and starts researching from scratch. In English, while the documentation is in German. By phone, when the colleague is on holiday.

Knowledge-based maintenance strategies are recognized as a key factor in managing the growing complexity of modern production systems and improving machine availability and process stability. Yet many companies lack the necessary competencies and capacities to unlock this potential.

The structural root cause is usually the same: there is no central system that consolidates knowledge, makes it accessible, and connects it to the right moment, the moment when a technician is standing in front of a broken machine and needs to make a decision.

The Intelligent Maintenance Assistant: Knowledge That Is Always Available

It is exactly for this moment that the Intelligent Maintenance Assistant (IMA) from WAKU Care was developed. Not as a database you search when you have time. But as an assistant that delivers the right information at the right moment, via text or voice, on a smartphone, directly at the machine.

What the IMA Can Do in Practice

Intelligent Search Across All Knowledge Sources
The IMA simultaneously searches manuals and manufacturer documents, past tickets and incidents (Cases), documented maintenance measures, checklists and templates, and the company-wide Knowledge Hub. The technician asks a question. The IMA delivers an answer, drawn from all available sources, prioritized and clearly presented.

Voice Input for the Shopfloor
A technician working underneath a machine cannot operate a keyboard. The IMA understands voice input. They can describe a fault, ask a question, or document a measure without interrupting their work.

Knowledge from Historical Incidents
Every completed fault report, every documented Work Order, every captured solution becomes part of the knowledge base. The IMA connects new symptoms with past events and suggests solution paths that have already proven effective.

Location-Independent, Cross-Language, Around the Clock
The IMA is available to every team member, regardless of whether the most experienced colleague is on holiday, on a different shift, or in a different country.

What This Means for Operations: Concrete Impact

Fewer Unplanned Failures

According to an Accenture study, unplanned stoppages can be reduced by up to 70 percent through the use of structured maintenance data and predictive approaches. Research by the US Department of Energy points to similar results: machine failures can be reduced by 70 to 75 percent, downtime shortens by 35 to 45 percent, and productivity increases by 20 to 25 percent.

These figures depend on knowledge being consistently captured, evaluated, and made accessible. That is precisely the foundation the IMA creates.

Faster Problem Resolution, Shorter MTTR

When a technician can access previous solution approaches within seconds, instead of working through manuals or calling colleagues, the time to resolve a fault decreases significantly. Research shows that predictive maintenance programs lead to a reduction in maintenance costs of 25 to 30 percent. Centralized knowledge management is the prerequisite for these programs to work at all.

Knowledge Stays in the Company

When an experienced technician leaves the company, their documented knowledge remains in the system. New colleagues become productive faster because they can access proven solution strategies. 91 percent of executives surveyed in a study agreed that better access to knowledge enables employees to work faster and more efficiently.

Accelerated Onboarding and Induction

A new technician who can use the IMA is ready for deployment more quickly. They do not need to memorize every characteristic of every machine. They ask, and the system answers.

From Individual Experience to Collective Intelligence

The real promise of the IMA is not just the individual query. It is the transformation of individual experiential knowledge into collective, structured intelligence.

Every fault that is documented, every solution that is captured, every checklist that is completed makes the overall system smarter. Over time, a living knowledge base emerges that does not diminish when someone leaves the company, but grows with every completed incident.

Academic literature increasingly identifies knowledge as a critical resource in the face of rising machine complexity. In particular, the externalization of implicit knowledge, that is, the transfer of personal experiential knowledge into structured, shareable forms, is regarded as a decisive lever for sustainably efficient maintenance.

That is exactly what WAKU Care delivers with the IMA: the expertise of the best technician becomes accessible to the entire team, at the right time, in the right place, in the right language.

How to Get Started

The IMA is not a separate system that requires its own implementation. It is an integral part of WAKU Care and works directly with the data that is generated in the system anyway: Tickets, Work Orders, Cases, Asset Record Files, and the Knowledge Hub.

This means: the more your team works with WAKU Care, the more capable the IMA becomes. The first documented incident is the beginning of a growing knowledge base.

How knowledge flows with WAKU Care:

1. Capture: Technicians document faults, measures, and solutions directly in the system, via voice or text, mobile at the machine.
2. Connect: WAKU Care links incidents with assets, components, timeframes, and frequencies. Patterns become visible.
3. Retrieve: The IMA makes this knowledge available in seconds, contextualized, prioritized, for everyone on the team.
4. Grow: Every new incident expands the knowledge base. The system gets better with every use.

Real-World Example: How Dexory Made the Transition

Dexory, a leading company in warehouse robotics, uses WAKU Care for the maintenance of its autonomous robot fleets. The challenge: decentralized systems, many different asset types, high coordination effort.

With WAKU Care, fault reporting and documentation now runs digitally, traceably, and without any system breaks. What previously ran across various channels is now in one place.
