Understanding and Managing Tribal Knowledge

Tribal or legacy knowledge — the practical tips and tricks frontline workers learn on the job but aren't in the official documentation — is essential to many manufacturers' smooth operations. This knowledge helps them work smarter and more efficiently, and there are risks to keeping it locked up in veterans' heads or workflows.

The aging manufacturing workforce is making this an acute problem: About a quarter of today's manufacturing workforce is age 55 or older, and when they retire, all of the knowledge they've accumulated over their career will be gone.

For this reason, documenting your frontline's tribal knowledge is vital to maintaining operational continuity, avoiding compliance problems, and ensuring long-term success for manufacturers. Let’s explore what tribal knowledge is, why it’s important, and how to harness and institutionalize this invaluable resource effectively.

What Is Tribal Knowledge?

Tribal knowledge is the unwritten insights, skills, and expertise employees accumulate on the job and often share informally through personal interactions or hands-on experience. It's also known as tacit knowledge, implicit knowledge, legacy knowledge, or unwritten lore.

This information is crucial for day-to-day operations, yet it generally remains undocumented and inaccessible to the broader organization.

Tribal Knowledge vs. Institutional Knowledge

These two terms are often used interchangeably, but they have a meaningful distinction:

• Tribal knowledge is the "secret sauce" that lives informally within a group of people — undocumented, passed down through word of mouth, and often invisible until someone leaves. For example, knowing the exact feel of a conveyor belt's tension that indicates it needs adjustment.
• Institutional knowledge includes everything an organization knows, from tribal knowledge to formal documentation.
  ‍

Unlike formal training materials or operational manuals, tribal knowledge lives in the minds of experienced workers, making it a valuable yet fragile resource. 

Examples of Tribal Knowledge

There are many ways tribal knowledge becomes vital for troubleshooting, innovation, and efficiency. These might include:

• Recognizing machine quirks, like knowing that a certain sound indicates a broken fan belt or that you need to apply pressure at a certain angle for optimal performance.
• Applying workarounds that aren't part of SOPs to fix recurring problems or prevent quality defects.
• Boosting productivity by discovering novel ways to assemble parts faster or reduce waste. 

The Compliance Risk of Undocumented Workarounds

Most of the time, these workarounds are used to optimize or improve manufacturing outcomes. However, some undocumented workarounds might unintentionally violate compliance or regulatory requirements. 

Unless you make the effort to document frontline workflows, these could slip through the cracks, opening you to fines, reputational damage, or other risks.

Pros and Cons of Tribal Knowledge

Think of tribal knowledge as an asset that bridges the gap between theory and practice. Organizations that effectively harness this knowledge can reduce errors, shorten onboarding times, and enhance productivity.

Is Tribal Knowledge Good?

Allowing workers to accumulate and share knowledge is essential to continuous improvement, such as:

• Operational efficiency: Frontline workers' learned experience creates shortcuts that help machines work at peak performance.
• Organizational agility: The people closest to the line can troubleshoot and make adaptations in real time to fix problems faster.
• Cultural benefits: Demonstrating that you value your frontline by honoring their expertise improves employee engagement, satisfaction, and retention.

Is Tribal Knowledge Bad?

The biggest challenge of tribal knowledge is its undocumented nature, which can create challenges such as:

• Operational bottlenecks: When employees leave — whether through retirement, job changes, or unforeseen circumstances — their knowledge often leaves with them, creating gaps.
• Manufacturing inconsistencies: If tacit knowledge is held by a few "gatekeepers," it may create quality or other inconsistencies between shifts.
• Knowledge hoarding: Withholding vital information from co-workers to protect job security can produce a toxic culture.
• Duplicated effort: Workers may spend time and labor solving problems that others have already fixed.
• Safety and compliance issues: Bypassing official protocols may risk equipment damage, injury, or regulatory fines. 
• Scalability barriers: When best practices aren't documented, it's difficult to expand them to other teams or new employees.
• Resistance to innovation: Over-reliance on legacy knowledge can create a "we've always done it this way" culture that creates barriers to new technologies or workflows.

Eliminating these drawbacks is why it's critical to document your tribal knowledge.

How to Capture Tribal Knowledge

Identifying, documenting, and disseminating tribal knowledge can be time-consuming, but it is essential for preserving critical insights and making them accessible to the entire organization. 

Here’s how to do it:

1. Identify Key Knowledge Holders

Start by consulting with managers and team leads to pinpoint individuals with critical insights into daily operations. Also, spend time observing the shop floor and doing skill assessments to uncover informal leaders with deep knowledge and experience that others rely on.

2. Extract Tribal Knowledge

Next, use structured interviews and knowledge-sharing sessions to extract insights from key knowledge holders. Use open-ended questions to encourage them to explain processes, provide tips, and share troubleshooting methods in detail. Group workshops and collaborative sessions may foster an environment of open communication and mutual learning for gathering information. 

3. Validate What You've Learned

Some tribal knowledge might be outdated, incorrect, or risky to the business. Before you institutionalize undocumented daily practices, have subject-matter experts review and validate their accuracy and efficacy.

Also, if you have a lot of tribal knowledge to document, prioritize the things that matter most, such as safety-critical processes or practices that protect your bottom line, versus "nice-to-have" efficiency tips.

4. Document Tribal Knowledge

Next, document tribal knowledge in an organized, easily retrievable way. Use structured frameworks, such as step-by-step guides or templates, to ensure consistency. Video recordings, process flowcharts, and centralized digital repositories make the information accessible and useful for a broad audience. This ensures that tribal knowledge is preserved, actionable, and a continuous asset to the organization.

Four popular formats for documenting knowledge are:

• Traditional training: Structured training programs are useful when you have a lot of information to share, such as during new-hire onboarding.
• Traditional documentation: Make manuals and other written documentation searchable and available on mobile devices for quick access. 
• On-the-job videos: Record a worker demonstrating their learned knowledge to a newer worker.
• Step-by-step digital workflows: Illustrated workflows accommodate operators who speak different languages, have certain disabilities, or have low literacy in the local native language.

5. Continue Accumulating Tribal Knowledge

Employees never stop learning, and giving employees the tools and opportunities to exchange insights is key to cultivating a knowledge-sharing culture. 

• Encourage open communication, recognize and reward employees for their contributions, and integrate knowledge sharing into performance evaluations.
• Provide tools for workers to exchange insights, such as regular team meetings or shared digital spaces, 
• Implement systems and processes to quickly capture and preserve valuable insights.
• Mine your frontline logs, machine logs, frontline chats, SOPs, and other documentation using AI to unearth newly discovered insights.
• Update your documentation regularly to incorporate new knowledge.

How to Share Tribal Knowledge With Employees

Turning tribal knowledge into institutional knowledge can be time-consuming to create and challenging to keep up to date — but it's necessary to turn critical expertise into a lasting organizational asset. 

Make sure your frontline workforce has clear opportunities and multiple ways to access the information you've documented. These may include:

• Mentorship programs: Identify experienced workers on each shift to serve as mentors to co-workers.
• Daily standups: Team meetings at the start of each shift are an excellent place to share new information or demonstrate new techniques.
• Frontline collaboration platforms: Connected workforce solutions create a "smart factory" environment by empowering operators to communicate and collaborate around real-time data.
• Learning management systems: Use an LMS to document upskilling opportunities, training, and compliance, so you know which workers haven't yet learned new processes or information.
• Digital communication devices: Mobile devices — whether company-owned or employees' personal devices with enterprise applications installed — are an ideal way to communicate with workers, especially when paired with a connected workforce solution.
  ‍

By utilizing technologies such as tablet devices, real-time data collection tools, and mobile communication platforms, organizations can automatically capture and disseminate critical insights. These make information accessible to all employees and help ensure that knowledge is continuously updated and seamlessly integrated into workflows. Digitally connected systems help bridge gaps between workers, fostering more effective collaboration and operational continuity.
