How To Replace Tribal Knowledge

Fri, 10/07/2011 - 11:22am

Some experts estimate that, of the 11 million manufacturing employees now working in the U.S., approximately 25 percent (or 2.7 million) are 55 years of age or older. Replacing these people is a big problem for manufacturing because they are the most experienced and usually the most skilled people working in a manufacturing plant, and the knowledge base is about to leave with them when they retire. In many industries, a good deal of the knowledge and solutions are not written down — they are in the workers’ heads. I call this “tribal knowledge” and it is not only more important than most corporations will admit, it is also a driving force behind innovation. Every manufacturing company needs to assess written knowledge versus tribal knowledge. At the same time they need to identify the “tribal knowledge gurus” in the company. The objective is to download their brains and get the knowledge documented before they walk out the door. This critical knowledge is often a big part of the company’s competitive advantage and is also the basis of the training for their replacements.

When I was a general manager of a custom machine manufacturer, I struggled with this problem for years. I never made a lot of progress trying to capture key tribal knowledge but, in retrospect, I think I would have approached the problem as follows:

  • Identify the knowledge gurus — Some of our field service people had worked on all of the machines that were ever built. Two or three had a reservoir of knowledge, service tips, repair tricks, and machine idiosyncrasies that nobody else had. But, as technicians, they did not like to write and it required special techniques to get the information downloaded from their brains. There were also two engineering managers and two in sales who had almost all of the information on costs and prices. They had all been involved in developing costs, prices, and quotations for more then 25 years and a good deal of it was not written down and only in their memory. Had these four gotten bubonic plague we would have been out of business.
  • Identify the knowledge — In the case of service techs, there was an enormous amount of service tips, diagnostic procedures, and information on how the older machines really worked that would be invaluable in service maintenance and operation manuals as well as training programs for the new hires. The cost/price information was also voluminous in terms of options, accessories, engineering solutions, and past applications that were all applicable to future sales opportunities. But if we could not get this information documented we could not train their replacements and the family jewels would still be in one basket.
  • Commit to the time — Both the downloading of the information and the development of new training programs is much like an apprentice program that will lead to journeymen. One must accept the fact that it is a long-term investment that may be three to five years. As soon as it is practical, it is necessary to appoint the people who are likely to replace the gurus to both learn from their mentors and to get the tribal information onto paper.

The cost justification is always difficult because you are asking management to invest. The costs for the additional labor and training costs could be in the hundreds of thousands and it is difficult to pin down in a return on investment formula. But the danger of doing nothing is endangering millions of dollars in future sales. This problem is not going to be solved by just an aggressive hiring program of new people after the gurus have retired. It will take a long time to transfer all of the skills and knowledge needed to replace the baby boomers with most of the tribal knowledge.

Using Older Workers
Once you have identified the people who have valuable tribal knowledge or who have skills that are difficult to replace, see how many of them are approaching retirement age. The next step is to develop a human resource program to retain and use them.

  • Some older workers may still want to work or may need to work because their retirement benefits are inadequate. If they are knowledge gurus, it is wise to develop a staffing strategy to allow them to work part time as employees or on a contractual basis.
  • If their retirement is a defined benefits program that doesn’t allow them to be re-employed, then develop an agreement with a separate company to “lease back” the special employees.
  • These older workers can also be used for projects that require special expertise. These could be short term projects for design engineers or installation projects requiring project management skills. Perhaps this may require recruitment of retired employees with special skills for the length of a contract.

Recruiting New Employees
Recent surveys show that many companies do not want to retain older employees. Instead, according to an article by KM World, they are going to “fill future talent tracks by relying on an aggressive recruiting program for new employees.” The CEOs who say this are probably not close enough to the key workers with the tribal knowledge and don’t know the real value. This is problematic when it comes to manufacturing of industrial products which require a lot of skills — especially since a recent survey by the Fabricators and Manufactures Association showed that “52 percent of teens have little or no interest in a manufacturing career and another 21 percent are ambivalent.” Those companies who have decided they are going to aggressively recruit new employees are going to have to overcome a negative image. The ongoing publicity of outsourcing, plant closures, union busting, and cyclical industry layoffs has not sold young people, teachers, parents, and school counselors on American manufacturing as a career.

I think to overcome the image and security problems, manufacturers are going to have to make a commitment to long-term (three to five year) training programs as well as long-term employment security. So far, most large corporations have said they are looking for highly skilled people, but I haven’t heard any of them commit to funding a three to five year training program to develop these skills.

Getting Practical
So, in looking at these problems in the short term, I think the two most practical solutions are to do everything possible to capture the valuable tribal knowledge and to develop strategies to retain older workers.
Have you done an assessment in your company that identifies the older workers and the knowledge that is about to walk out the door?
