“All animals are equal, but some animals are more equal than others.”

This quote from George Orwell’s political allegory, Animal Farm, occurred to me recently as I listened to a design engineer explain to me how he was taught in college that engineers have a special responsibility to help their less able co-workers.  Not intending to single out engineers or generalize from one data point, this example demonstrates what I observe to be a longstanding preoccupation with degrees, certificates, and belts.  We may refer to employees on the front line as “value-adding”, but too often it’s the ones with letters after their names that we actually value.

In 1957, Peter Drucker dubbed the latter group knowledge workers, “high-level employees who apply theoretical and analytical knowledge, acquired through formal education,” thereby inadvertently differentiating the thinkers from the do-ers, the high level from the low level, the brain trust from the variable expense.

My personal experience with this distinction developed over a period of years as I changed jobs, first from marketing to IT and then to production.  In the eyes of my fellow managers, I morphed in the process from an imaginative idea person into a brainy techno-geek and finally to a slow-witted grunt.  The adjectives are important because they connote associated stereotypes.  I joke that I started near the top and then worked my way down, IQ dropping along the way.  Paradoxically, my knowledge of value and waste increased each time I got further from that theoretical and analytical knowledge and closer to the floor.   John Shook noted at the 2016 Northeast LEAN Conference, the persons who do the work are the real knowledge workers, as they are the ones with a first-hand understanding of the work.   (Incidentally, our 2017 Northeast Lean Conference is on the horizon. Check out the agenda.)

Whether in a factory or an office or an operating room, the knowledge is contained in the work.  In that sense, all work should be knowledge work if we are thinking about it and trying to improve it.   Steve Spear refers to Lean transformation as “theory proven by practice.”  Both are essential and should be inextricably linked.   Our Lean transformation should have room for both the theorists and the practitioners.   Unfortunately, when it comes to transformation, some employees are “more equal than others.”   We favor the theorists and mostly ignore the practitioners.  Perhaps our love affair with a college education and degrees and certificates and belts has baked in a two-class society where only a select few employees are heard and seen; the rest fall into that eighth waste category of “lost human creativity.”  I’ve assembled a short list of nouns and adjectives commonly used to describe these classes. Can you think of others?  Please share.

The Final Frontier

On May 5, 1961, Alan Shepard became the first US astronaut to journey to the “final frontier.”  Atop a Mercury rocket, Shepard launched into a fifteen-minute suborbital journey reaching an altitude of about one hundred miles before returning to earth.  His space capsule, Freedom 7, was a wonder of science weighing a little more than one ton and loaded to the max with avionics and life support apparatus. Yet, this pioneering venture into endless space would also afford almost no space for the passenger.  According to launch engineer, Guenter Wendt, “astronauts entered their capsules with a shoehorn and departed with a can opener.”   I remember watching footage of Shephard squeezing into his capsule.  The memory still creates pangs of claustrophobia.

Ironically, space constraints faced by NASA fueled a revolution in miniaturization evident in almost every innovation of modern society – from laptops to cell phones to transportation to medical devices to all things Internet.  The need to pack more utility into a small package has changed everything.  Or almost everything.  Here are some recent exceptions:

“We’re adding a new wing to manufacturing,” a colleague related to me recently, “we’re running out of space.”   As I glanced around a shop floor crowded more with material than machines, I asked, “What are you going to put in the new space?”  “We’re just going to spread out,” he said.  “This is a good time to build before interest rates start to climb.”

Another manufacturer advised recently that he was building a Lean warehouse.  “What’s that?” I asked.   “We’re relocating all of our raw material to a location that’s closer to the main highway,” he said. “We need to add several machines, so were Lean-ing out the space.”    “Aren’t you just adding more space and moving inventory farther from your floor?”  I asked.  His response: “Warehouse space is cheap.”

A major hospital requested Lean assistance to re-design its perinatal services in order to accommodate more patients.  After reviewing the current operation, I recommended that existing space could be repurposed to handle the projected growth. “No,” they said, “We’re cramped. We need more space and the budget is already approved.”

It seems that decisions regarding space are driven more by claustrophobia or perceived worth than actual need.   Flow distance may double or triple as a result of expansion, but additional space somehow still equates to growth.   More space is viewed as an investment, an alluring addition to the balance sheet, or a badge of success.   Only on rare occasions do I encounter a growing business that is interested in reducing space. Perhaps, then, space is the final frontier.  Not more space, but less.   I wonder how much Lean progress would be made if space were seen as a constraint for business as it was for NASA’s Mercury launch.

How much space do you have?  Too much?  Too little? Share a story.

Systems Tinking

At GBMP’s launch of the Shingo Institute’s BUILD EXCELLENCE workshop, it occurred to me that perhaps systems thinking might be more aptly named systems rethinking.  Workshop participants offered up current systems in their organizations that actually impeded continuous improvement, each time expressing frustration with the difficulty to create system change.  For larger organizations with more explicit codification of systems, the task to create a change was more onerous.  One class participant commented, “Our standard procedures are documented in dozens of binders – all of them covered with dust.”   But even in smaller organizations, creating a new system will mean undoing a de facto process that, despite its shortcomings, feels normal.

According to the Shingo Institute, these systems are the domain of managers who should be reviewing them regularly.  But, when business systems are ingrained as part of the corporate fabric, the idea of changing even one of them instills concern regarding the global effects.  Will changing one system negatively impact others?  Concern for unanticipated consequences will trigger risk-averse behavior.  Add to that challenge the fact that existing systems may, in fact, have been authored by the same persons who are now charged with evaluating their effectiveness.  When Shigeo Shingo declared that subjective inspection of one’s own work is not good practice, he might have included the work of managers along with that of front line employees.    It would be better apparently for these organizations to have no systems to start their Lean journeys than to be saddled with status quo systems that evoke the wrong behaviors.  So, what can be done?

According to the Shingo Institute:

First, stop basing the design of systems purely on local results.  This practice creates silos and disharmony.  Each part of the organization is rewarded as if it were its own company, rather than for its contribution to system goals.   Speaking at a Shingo Conference many years ago, Russ Scaffede, formerly an executive at General Motors (and later at Toyota) quipped, “At GM we used to say ‘All of our divisions made money, only the corporation lost its shirt.’”   That is the status quo condition for many organizations: local bogeys driven by systems that simply don’t knit together.

Second, consider the foundational principles beneath the Lean tools, or, as Shigeo Shingo noted, first ‘know-why’ before you ‘know-how.’  Many organizations parrot the tools without understanding the philosophy that makes them effective.  Simply layering tools on top of a faulty philosophy also generates disharmony rather than real results.   Many organizations, for example, have invested time to develop a quality system like ISO including QC tools and problem-solving methods; but employees are afraid to report problems for fear of reprisal.  Shingo Principles articulate the culture that must be present to make systems work.

sytems_tinkeringFinally, to avoid concerns regarding the interdependency of systems, i.e., the unanticipated consequences make the changes small; in the words of Masaaki Imai, “create many small changes for the better.”   Don’t let the policy books gather dust; review and update them often.   To use a metaphor from knitting,  check and adjust your systems one thread at a time.  Don’t let the knitting unravel.  It’s called tinking, the process of taking knitting back stitch by stitch to correct a problem in the fabric. (Tink is knit spelled backward.)   In this case, let’s call it “Systems Tinking.”

P.S. Speaking of the ‘know-why’ before the ‘know-how’, GBMP’s  Lean conference is coming to Worcester MA on September 19-20. The theme for our 13th annual event – “The Integration of Culture & Tools” – will be an exploration of the value of Lean tools when embedded with a Lean culture. I know September feels like a long way off, but it’ll be here before you know it. The event features four keynote presenters including Paul Akers, author of ‘2-Second Lean’ & Brian Wellinghoff from Barry Wehmiller, plus 30+ breakout sessions and more than a dozen poster presentations for yokoten in our Community of Lean Lounge. Simply put, it’s the best opportunity for Lean learning and networking with professionals just like yourself – passionate Lean practitioners. Early bird registration discount (save close to $200!)  in effect through May 31. That’s tomorrow folks. I hope you take advantage of the savings. But don’t take my word for it. Check out the agenda at a glance, testimonials and photos from last year’s event and much much more on the website and decide for yourself. I sure hope to see you in September!
