5 ways to lose critical tacit knowledge (hint: and how to avoid them)
Sep 09, 2025
Tacit knowledge is fragile. Over-reliance on dashboards, failure to recognise contributions, silos, poor succession planning, and neglected networks all erode it. This article shows how leaders can avoid the most common traps.
Every organisation has more knowledge than it realises. Not the data in dashboards, or the policies in binders, but the lived experience of people who know how things really work. This is tacit knowledge—the unwritten know-how that guides judgment, foresight, and effective action.
The problem? Tacit knowledge is fragile. It can be lost in subtle ways that leadership only notices once performance slips or strategy derails.
Here are five of the most common ways companies undermine tacit knowledge—and how to avoid them.
This article is part of our series on challenges where collective tacit knowledge is decisive for boards and senior managers.
1. Over-reliance on dashboards and data
Dashboards are essential, but they tell you only what can be measured—and usually after the fact. By the time a KPI shows a supplier relationship is unstable, buyers may already have sensed trouble months earlier.
When leaders prioritise only what the data confirms, they silence weak signals. Tacit knowledge—those early warnings drawn from experience, intuition, or subtle observations—never reaches the boardroom.
How to avoid it: Balance hard data with human insight. Make space in executive and board discussions for “what we sense but can’t yet prove.” Treat judgment calls as inputs, not noise.
2. Failure to recognise tacit knowledge contributions as assets
Tacit knowledge doesn’t live in systems—it lives in people. When those contributions are invisible, employees disengage. A project manager who quietly prevents recurring supplier disputes may deliver more strategic value than a colleague who simply hits every KPI, but rarely gets recognised.
Failing to value tacit contributions sends the message that they don’t matter. Over time, employees stop sharing insights or take them to competitors who do appreciate them.
How to avoid it: Recognise tacit contributions explicitly. Acknowledge how know-how, foresight, and judgment shape outcomes. Incorporate tacit contributions into talent reviews and strategic discussions.
3. Siloed teams
Tacit knowledge is often trapped inside departments. Operations sees one set of risks, procurement senses another, compliance a third. Without mechanisms to bring these fragments together, boards make decisions with a partial picture.
In sustainability especially, silos are dangerous. A supply chain initiative may look efficient to operations but expose reputational risk that only marketing perceives. Without shared tacit knowledge, the blind spots multiply.
How to avoid it: Create cross-functional forums where tacit insights are shared openly. Use scenario-based discussions at board level to surface different perspectives. Encourage leaders to ask: “What are we seeing that others may not?”
4. Poor succession planning
Leaders eventually leave. When they do, years of experience walk out with them—unless tacit knowledge has been intentionally passed on. Too often, succession planning focuses on formal skills, overlooking the judgment and networks that make leaders effective.
The result: successors inherit the role but not the nuanced know-how that enables sound decision-making. Teams lose confidence, and costly mistakes follow.
How to avoid it: Make succession a process of knowledge transfer, not just role replacement. Pair rising leaders with mentors who share tacit insights. Build reflection into handovers, not just technical briefings. Treat succession as preserving strategic memory.
5. Neglecting informal networks in the virtual era
Before hybrid and remote work, tacit knowledge flowed through corridor chats, coffee breaks, and shared travel. These informal exchanges carried tips, warnings, and workarounds that never appeared in reports.
In today’s virtual world, those spontaneous touchpoints have diminished. Without intentional design, employees become isolated in transactional meetings. The soft signals of tacit knowledge fade away.
How to avoid it: Create opportunities for informal exchange, even in hybrid setups. Host short peer-to-peer forums, set aside time in meetings for open sharing, or design “safe space” conversations. Tacit knowledge thrives in trust, not only structure.
Conclusion
Tacit knowledge is one of the most strategic assets your organisation holds—yet it is also the most fragile. Over-reliance on data, failure to recognise contributions, silos, weak succession planning, and neglected networks all erode the invisible glue that holds performance together.
The result is more than knowledge loss: it’s a loss of resilience, foresight, and the ability to align sustainability with profitability.
Leaders who want to protect their organisation’s future must act deliberately to value, share, and sustain tacit knowledge.
