Consulting

In the US, many use the Japanese word “Sensei” for the people who help companies implement Lean; in Japan, they use the English word “Consultant.” On both sides, words borrowed from the other’s language have snob appeal, and give the jobs a mystique it doesn’t need or deserve.

See What to Expect from Lean Manufacturing Consultants for  a Japanese perspective on this profession. As I also pointed out earlier, “sensei” (先生) is the Japanese word for school teacher. As a title, it is used through High School but not in Universities. You might use it to say that a person teaches at a university, but there is another word for “Professor” (Kyoju).

In Karate, there are six levels of instructors, from Deshi to Soke, and Sensei is the second lowest. The word is also attached to people’s names as a form of address, instead of “San,” either to make them feel respected for their expertise or sarcastically. It is nothing special.

In Lean, there is nothing a “Sensei” does that is different from what a good consultant would do. There is no need for new vocabulary. Consulting involves a business relationship that is different from employment, but the same kind of agreement also covers contractors as well as consultants.

What is the difference?  Most people don’t see any, and many contractors call themselves “consultants.” The key distinction is that a contractor works like a temporary employee, while consultants advise, train, and coach employees. The contractor’s output is more tangible, but the ability to produce it walks out with the contractor, whereas the consultant transfers know-how that remains after the end of the engagement.

You hire a contractor to write control software for your production equipment, because you don’t have engineers who can do it, and you don’t think you have a need for this skill on an on-going basis. If, however, you think it should be available in your organization, you may bring in a consultant to help your managers set strategies and policies on equipment control programs, select tools, and learn how to use them.

There are as many ways to work as a consultant as there are fields in which they are needed. Often, the know-how they transfer is procedural. They tell companies how to comply with regulations, pass audits, get ISO certified, or win the Shingo Prize.

Less often, it is about thinking through business strategy and finding the right moves in management and technology to be competitive. It is much more challenging, and there is no 12-step methodology for it. Lean consulting is in the latter category, because Lean implementation cannot be reduced to a procedure to be rolled out without thinking in every organization, whether it makes sausages or airplanes.

It is challenging, but it is what high-level consultants have been doing ever since Frederick Taylor invented the profession 125 years ago. It does not need a new name.
