Imagine a veteran machine operator in an aerospace factory pausing mid-shift after recognizing an unusual sound from a turbine. An early warning that, if ignored, could trigger a costly breakdown. This type of\u202fimplicit knowledge, built through decades of hands-on experience, exists nowhere in manuals or standard operating procedures. Yet, according\u202fto\u202fthe\u202fPublications Office of the European Union<\/span><\/mark><\/a>, workers aged 55\u201364\u202fare\u202fexpected to make up\u202f30% or more of the workforce\u202fin many EU countries by 2030. European manufacturers, therefore, face an urgent challenge: critical expertise is increasingly concentrated in an aging workforce representing a pool of skilled labourers that continues to shrink.  
 
How, then, can organizations document this knowledge before expert employees retire? This article aims to explore practical strategies for capturing and transferring expertise before it leaves the organization. <\/p>\n\n\n\n

The Real Cost of Losing IMPLICIT Knowledge<\/strong><\/h2>\n\n\n\n

Implicit knowledge is the collective wisdom, unwritten best practices, and intuitive expertise that veteran workers develop through years of hands-on experience. Unlike documented procedures, it exists only in people\u2019s minds. This knowledge often determines whether operations remain stable or escalate into costly disruptions. When tribal knowledge disappears, manufacturers do not just lose experience; they lose a critical layer of operational resilience affecting safety, efficiency, and quality. 
 
EU population projections<\/span><\/mark><\/a> indicate that the working-age population could shrink from 239 million in 2015 to around 217 million by 2050. Data from the\u202fEuropean Labour Force Survey<\/span><\/mark><\/a> shows that nearly one in five workers is aged 55 or older in Germany, Finland, and Sweden. In Germany alone, reports on Aging and regional productivity growth<\/span><\/mark> <\/a>indicate that the average workforce age has increased from 41 to 44 since 2000. This demographic shift fundamentally changes how industrial organizations must approach long-term operational resilience. 
 
The consequences are already becoming visible. Research in Process Safety Progress<\/span><\/mark><\/a> shows that 27% of major accidents in European process industries involved shortcomings in situational awareness and decision-making, highlighting the risks of relying solely on formal training to develop these skills. The most at-risk knowledge includes\u202fequipment-specific quirks, process optimization shortcuts, crisis response behaviors, and visual inspection judgment. A deliberate approach to\u202fimplicit knowledge transfer is crucial in preserving these capabilities. <\/p>\n\n\n\n

It\u2019s worth noting: <\/strong>long fixations don\u2019t always signal interest\u2014they can also indicate confusion or show that there is a lot of information available that needs to be perceived. Context is key. <\/p>\n\n\n\n

Why Traditional Approaches Fall Short<\/strong><\/strong><\/strong><\/h2>\n\n\n\n

Organizations have long relied on two primary methods to preserve operational\u202fexpertise: written documentation and direct mentorship. Both are valuable and necessary. But as workforce demographics shift and operational complexity\u202fincreases, their limitations are becoming increasingly difficult to ignore. <\/p>\n\n\n\n

The Documentation Problem<\/strong> <\/h3>\n\n\n\n

Written standard operating procedures and work instructions are essential, but they primarily capture knowledge that can be audited. They often fail to reflect the experience-based insights developed over decades of hands-on work. 
In practice, documentation competes directly with production priorities. Even when it exists, documentation often lags behind operational reality as equipment ages, processes are optimized, and informal workarounds emerge. This widening gap between documented procedures and everyday practice represents a growing risk. <\/p>\n\n\n\n

The Mentorship Gap<\/strong> <\/strong><\/h3>\n\n\n\n

Mentorship and job shadowing enable valuable knowledge exchange, but their effectiveness can be inconsistent. Transfer often depends on individual communication skills, availability, and the assumption that expertise can be explicitly explained. The one-to-one nature of mentorship also makes it difficult to scale. And as older employees make up an increasing share of the workforce, the time available for structured handovers becomes progressively limited. 

A systematic way to verify whether critical knowledge has been transferred and retained is not always given. For organizations facing simultaneous retirements across multiple roles, this creates a fragile dependency on informal knowledge exchange. 

Importantly: traditional methods often focus on what experts say, rather than what they actually see and do in critical moments. Overcoming this limitation requires a shift toward methods that capture expertise as it is performed, instead of after the fact. <\/p>\n\n\n\n

What makes expert knowledge different<\/h2>\n\n\n\n

What sets manufacturing experts apart is how they\u202fperceive situations in real time. Their knowledge is largely visual and intuitive, making it difficult to verbalize; they rely on\u202fefficient attention, not more inspections. 
 
In particular, senior technicians develop optimized visual scan patterns that focus on areas most likely to indicate risk or failure. This perceptual efficiency enables faster, better decisions, yet it is rarely captured in documentation or training.  
 
The key insight:\u202fto transfer expert knowledge, organizations must capture where experts look and what they notice. <\/p>\n\n\n\n\"\"\n\n\n\n

5 Strategies to Preserve Expert Knowledge<\/strong> <\/h2>\n\n\n\n

Preserving expert knowledge requires more than a single initiative. It calls for a practical mix of organizational, process-driven, and technological measures. When used together, these approaches help ensure that critical expertise is captured, transferred, and validated before it leaves the organization.<\/p>\n\n\n\n

1. Conduct a knowledge risk assessment<\/h3>\n\n\n\n

Preserving implicit knowledge starts with identifying where it resides and how vulnerable it is. Critical roles held by employees nearing retirement pose the highest risk. Prioritization should consider both the retirement timeline and the importance of the knowledge. Asking questions such as, \u201cIf [Expert] called in sick tomorrow, what would stop?\u201d <\/em>can reveal which skills are truly indispensable. A clear understanding of these risks provides a roadmap for targeted knowledge transfer and ensures resources focus on the areas with the greatest operational and financial impact.<\/p>\n\n\n\n

2. Create Structured Mentorship Programs<\/h3>\n\n\n\n

Once critical knowledge and at-risk employees are identified, structured mentorship programs help ensure it is systematically transferred. Pairing experts with successors\u202f18\u201324 months before retirement\u202fallows repeated, hands-on exposure, guided by a knowledge transfer checklist to capture key skills, insights, and decision-making patterns. When implemented early and consistently, mentorship transforms informal expertise into measurable, transferable knowledge, preparing successors to perform with confidence.<\/p>\n\n\n\n

3. Use Video Documentation Strategically<\/strong> <\/h3>\n\n\n\n

Video documentation presents a powerful tool for capturing experts performing critical tasks in real time. Further, when employees narrate their decisions, viewers gain insight not only into the actions but also the reasoning behind them. Organizing recordings into searchable libraries by equipment or task makes this expertise readily accessible to new hires when needed.

However, while video effectively shows what experts do, it cannot fully capture\u202fwhere they focus their attention\u202for how they visually process information. This limitation underscores the need for methods that record both expert action and perception, laying the groundwork for more advanced knowledge-transfer solutions.<\/p>\n\n\n\n

4. Leverage Eye Tracking for Visual Expertise<\/h3>\n\n\n\n

Eye tracking technology records where experts focus their gaze during real-world tasks, revealing perceptual and decision-making skills that traditional methods often miss. Unlike a standalone video, it shows not just what experts do, but\u202falso how they see and interpret their environment. 

Key insights captured include: <\/strong><\/p>\n\n\n\n
