Hamamoto, TIMEWELL.
Today I want to talk about an "organizational disease" that many companies are falling into without realizing it.
"Now where did that document go?" "That's something only Tanaka would know..." "Ever since my predecessor left, nobody knows how that process works..."
Does any of that sound familiar? If even one of these resonates, your organization may be suffering from the silent disease of knowledge siloing.
This article examines in depth why internal information retrieval is so inefficient — and how knowledge siloing, as the root cause, is holding back organizational growth. If your organization is struggling with information management or knowledge sharing, this article is meant to offer a way forward.
Chapter 1: The Time That Disappears — Why Does Searching Take 30 Minutes?
McKinsey research puts it at roughly 20% of a knowledge worker's time spent on information retrieval [1]. Assuming 2,000 working hours per year, 400 hours — about 50 working days — disappear into searching.
The number is striking. But for people in the field, it tends to feel about right. Working on ZEROCK at TIMEWELL, I've had the chance to speak with information systems teams and corporate planning departments at many companies. The one thing I hear consistently: frustration at the enormous time spent just searching for information.
Why is information retrieval so inefficient? Three structural factors.
Factor 1: Scattered Information — The Maze That Organizational Silos Create
The most fundamental problem: information lives across multiple systems and folders. Most organizations have different departments using different tools with different file management rules.
- Sales uses Salesforce for customer data
- Engineering manages technical documentation in Confluence
- HR stores policy documents in SharePoint
- Finance manages data in a proprietary accounting system
Cross-system search is difficult, which means every retrieval starts with a first-order judgment call: "which system should I check first?"
At one manufacturing company we worked with, seven different document management systems coexisted within the organization. New employees averaged over 40 minutes to reach the information they needed — a startling reality.
Factor 2: Inconsistent Naming Conventions — The Fragility of Relying on Human Memory
The second problem: file and folder naming conventions are not standardized.
"Proposal_FinalVersion," "Proposal_FinalVersion2," "Proposal_ActuallyFinal"
Most people have seen exactly this pattern. It sounds like a joke, but it causes serious problems.
When a file is created, the name feels perfectly identifiable in the moment. Three months or six months later, recalling the context of that name is hard. If you weren't the person who created it, finding it is even harder.
| Situation | Time to find file |
|---|---|
| File you created last week | 1-2 minutes |
| File you created 6 months ago | 5-10 minutes |
| File created by someone else | 15-30 minutes |
| File created by someone who left | 30+ minutes, or never found |
Table 1: Typical time spent searching for files
Factor 3: Knowledge Siloing — What Leaves When People Leave
The third problem: knowledge concentrated in individuals. "That's something only Tanaka would know" is a conversation that happens regularly in many organizations.
The know-how for specific business processes or customer handling exists only inside one person's head, never captured in a form that can be shared. This problem becomes acute when "Tanaka" leaves or transfers.
At one IT company we supported, when a key engineer resigned, it took over three months to reconstruct the system configuration that only that engineer had known. Knowledge accumulated over years survived only as fragments in a handover document — the majority lost to the organization permanently.

We have prepared materials covering ZEROCK case studies and implementation methods.
Chapter 2: The Three Consequences of Knowledge Siloing
Knowledge siloing can look efficient in the short term. "Just ask Suzuki and it's handled." "Leave it to Tanaka and you know it's right." But allowing this state to persist causes serious organizational harm.
Consequence 1: Operational Disruption Risk
In organizations with advanced siloing, key people's absence immediately causes work to stall — when they're on vacation, out sick, or when they resign. The organization takes real damage.
Research estimates that the knowledge loss cost from a single experienced employee's departure is equivalent to 50-200% of that employee's annual salary [2]. That includes not just replacement hiring and training costs, but the time and cost required to reconstruct lost implicit knowledge.
Consequence 2: Growth Constraints
Knowledge siloing severely limits organizational scalability. New people join, but without access to accumulated knowledge, they take a long time to become fully effective.
Siloed organizations also struggle to innovate. Knowledge confined to individuals means fewer opportunities for the combination of different knowledge sets that produces new ideas.
Consequence 3: Psychological Burden
Siloing creates real pressure on the people who hold the knowledge. "I'm the only one who knows this" creates a situation where you can't take time off, can't change jobs, even when you want to.
And the anxiety that "sharing what I know makes me less valuable" can trigger deliberate information hoarding — damaging organizational trust and healthy culture.
Chapter 3: Why Conventional Knowledge Management Fails
Many organizations that recognize the siloing problem have tried internal wikis or file server-based knowledge management. Success, however, is the exception rather than the rule.
The Hollowing-Out of Internal Wikis
Many organizations have launched Notion, Confluence, or custom wiki systems with instructions to "consolidate information here." The results, more often than not:
- Pages updated enthusiastically at launch go stale as contributors change roles or get busy
- What remains is outdated information — an "information graveyard"
- No incentive to update; inadequate search functionality
- "Nobody reads it, so nobody updates it; nobody updates it, so nobody reads it" — a self-reinforcing cycle
The Labyrinthine File Server
Similarly, file server management has reached its limits. Folder structures that have accumulated over years have grown far beyond their original design intent into something that nobody fully understands.
At one trading company we spoke with, the file server folder hierarchy had reached 12 levels deep — reaching a target file could require more than 10 clicks.
The Fundamental Limitation of Conventional Approaches
What these conventional approaches share: the assumption that "information must be stored correctly; retrieved through the correct path." This approach depends on human memory and behavioral consistency — and becomes increasingly fragile as organizations grow.
Chapter 4: A New Approach to Knowledge Management for the AI Era
So how do we break free from the serious disease of siloing?
Advances in AI — particularly large language models (LLMs) and RAG (Retrieval-Augmented Generation) — have made a fundamentally new approach possible.
From "Searching" to "Finding"
Traditional knowledge management required users to search the right keywords in the right place. AI-era knowledge management enables finding semantically relevant information regardless of where it's stored.
Rather than depending on file names or folder structures, you ask in natural language — "how do we handle customer complaints?" — and get relevant documents, past emails, and chat history retrieved cross-system.
Natural Accumulation Through Daily Work
Traditional knowledge sharing required "extra work" — deliberately writing documentation. AI-era knowledge management enables knowledge accumulating naturally through the process of doing the work.
Questions and answers in chat, research results, discoveries made during projects — saved to the knowledge base in one click. Knowledge builds up as an extension of daily work, not as a separate documentation task.
Converting Implicit Knowledge to Explicit
With AI, extracting implicit knowledge that was previously difficult to articulate becomes achievable. As experienced employees engage with AI in conversation, the dialogue log surfaces knowledge that can be saved as organizational knowledge — making explicit what the person themselves may not have consciously articulated.
| Conventional Approach | AI-Era Approach |
|---|---|
| Store in the right place | Find anywhere |
| Keyword search | Ask in natural language |
| Deliberate documentation | Accumulates through daily work |
| Implicit knowledge hard to share | AI extracts implicit knowledge |
| Manual updates | Automatic updates and consistency checking |

Chapter 5: ZEROCK — Democratizing Organizational Knowledge
"The ideal is clear. But building something like this from scratch in-house sounds like an enormous undertaking."
Many people reach this point. The answer is ZEROCK — TIMEWELL's enterprise knowledge AI platform, designed specifically to solve exactly the challenges described above.
Find Internal Information in 10 Seconds
ZEROCK's GraphRAG technology connects semantically related information scattered across an organization and delivers an environment where the right information can be found in under 10 seconds. Cross-system search across file servers, groupware, chat tools, and more.
AI Knowledge — Automatic Accumulation
ZEROCK's "AI Knowledge" feature saves knowledge generated through daily work in one click. Accumulated knowledge is automatically organized and related, becoming something anyone can use.
Convert Veteran Knowledge into Organizational Assets
Extract implicit knowledge through conversations with experienced employees and convert it into the organizational knowledge base. Even after departures or transfers, that knowledge remains in the organization.
Enterprise-grade security is built in from the start: IP address restrictions, single sign-on (SSO), and more — ready for large enterprise deployment.
Conclusion: Knowledge Is an Organizational Asset
Inefficient information retrieval and knowledge siloing are not merely an inconvenience. They are management challenges that directly affect organizational competitiveness.
- Reduce information retrieval time → that time becomes available for creative work
- Convert experienced employees' knowledge into organizational knowledge → greater resilience against attrition risk
- Consolidate scattered information → data-driven decision-making becomes possible
Going forward, organizations that move away from knowledge siloing — where everything depends on specific individuals — and toward managing knowledge as an "organizational asset" will gain competitive advantage.
