Who Cares for the Care Givers?

Last month I joined Eric Buhrens, CEO at Lean Enterprise Institute (LEI) to host a leadership team from the Tel Aviv’s Sourasky Medical Center.  They were on a study mission to many of Boston’s fine hospitals and were winding up their week in Boston with a visit to LEI.  Early in the discussion one of our guests asked, “In a few words, please tell me what Lean is.”   Eric fielded this question concisely, explaining “Lean means creating more value for customers with fewer resources.”   He then asked me to relate the following story, a bit more long-winded, to amplify the concept:

I had a recent sojourn of more than a few days at one of Boston’s finest hospitals affording me a rare opportunity for extended direct observation of the process.  In Lean lingo, I was observing from the point of view of the “object” of improvement —  the part to be worked on.  In a factory, the object of improvement is a piece of material, a part being progressively converted by agents of improvement into a finished product.

Clinicians bristle at this analogy.  People, after all, are not widgets.  Of course, I agree.  Patients are each of them unique, and the task to make them well is anything but standard.  Caregivers must often make split-second decisions based upon years of experience and practice, spanning an enormous range of different potential conditions.   They are indeed agents of improvement, operating singly and as a team, with a passionate commitment to making the patient well. From scrub techs to cleaners to docs, surgeons, nurses, and administrators, these caregivers adroitly shift gears from one minute to next, at one point calming a delirious octogenarian who is screaming in the middle of the night for a pepperoni pizza and then a minute later resuscitating a gentleman in cardiac arrest.  As one of their recent customers, I extend my gratitude.

Toast-Kaizen_TabletBut, as I note in the Toast Kaizen video, “continuous improvement is not so much about the work as the things that get in the way of the work.”

Therefore, please allow me to offer an example from my extended observation.  For a period of days, I was tethered to an IV connected by about six feet of plastic tubing to an infusion pump and IV solution bag.  The dosage rate required the bag containing the elixir to be replaced approximately twice per day.  I say approximately because the flow of medicine was interrupted on average once per hour by a pump fault – an airlock in the line. When an airlock was sensed the pump would pause and alarm.  A nurse would then come by to adjust the tubing above the infusion pump, clear the fault and continue the infusion.  Depending upon the level of activity on the floor, wait time for the nurse ranged from a minute to fifteen minutes.  Oddly, if the fault was not attended to in the first five minutes the alarm grew much louder.  This I am told is a countermeasure to “alarm fatigue”,  a condition which occurs when there are too many alarms to handle at one time.  My sense is that the increased loudness did little more to alert the nurses; it was just an addition to the ongoing cacophony of alarms sounding throughout the floor.  In my own case, however, the increased loudness caused me to hit my call button.  This sent a signal to the nurse’s station that, after hearing from me that my infusion pump was alarming, would summon the beeper my nurse was carrying.  Depending upon the level of the many non-standard things that could be happening on the hospital floor, this might elicit an immediate response – or maybe not.

WhoCaresPostWhen the pump alarmed, I understood that my need was not the most critical, but felt compelled to ask my nurse – actually multiple nurses over a period of days – what they thought might be done to reduce the incidence of airlocks in the line; for example, did they think the problem was caused by equipment malfunction or set-up or the viscosity of the solution, or perhaps a software issue?  Had they investigated the problem?  I was struck by their responses.

First, every nurse assumed that my questions regarding the pump were motivated by my own wellbeing. “No,” I exclaimed, “I’m not asking for myself, I’m inquiring on your behalf.  Your time is so valuable, I hate to see it consumed by these kinds of headaches.”  Still, the response was a long-suffering “we do whatever it takes to care for our patients.”  In the minds of caregivers, clearing pump faults was just an inevitable annoyance – part of the job.  The mindset, while admirably focused on the patient, was also resigned to the status quo of common annoyances.  “At what point does an annoyance become a problem?” I asked one nurse.  She responded simply “its hard to make changes.”  Then, pausing for a second, she reflected, “One of our technicians showed me a trick a while back that he said would reduce airlocks in the line.  Let’s give it a try.”  With that, she repositioned the tubing above the infusion pump.    Subsequently, the pump did not alarm for hours – not until a refill solution bag was needed!  The breakthrough here was not so much in the deployment of a potentially better method, but the realization by one caregiver that what she had considered an annoyance was actually a big problem.

Of course, this just a single point of observation, an anecdote.  I didn’t see the nurse again to thank her or ask her what trick she had applied.  I wondered who else on the floor knew about this trick and how many pointless interruptions to their incredibly valuable work could be reduced if the trick became a standard.

I concluded my story to the management team: “Your caregivers are your most valuable resource.  Management’s job is to create an environment in which the ‘things that get in the way of the work’ are exposed and corrected, enabling caregivers to fulfill their missions with more time and greater focus on making the patient well.”

What do you think? I’d love to hear from you.

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.

Ludicrous Speed

speedMel Brooks fans will remember Spaceballs, his jocular jibe at the Star Wars epic. In pursuit of a rebel ship, evil Lord Dark Helmet (Rick Moranis) orders his crew to accelerate their craft beyond the speed of light to “ludicrous speed.” While time travel remains science fiction, our ability to process and transmit data has proceeded apace since I was a young lean dude. In college we expressed data transmission speed as a baud rate, a unit of measure roughly equivalent to one alphanumeric character per second. Geeks like me sat at Teletype machines watching our computer programs transmit programs at the blazing speed of 32 baud (i.e. 32 characters per second) to a shared computer at Dartmouth College, which then processed that information at a rate expressed in IPS, instructions per second.   Information speed was severely limited by the transmission and processing technology of the day.  By the time I graduated college however, speed had progressed to MIPS, millions of instructions per second, then to billions, and more recently FLOPS.   The trend continues today, bounded only by theoretical limits, towards ludicrous speed.

Fascination with information speed has been with us since 1953 when the first commercial computer was sold. At that time UNIVAC (Universal Automatic Computer) processing speeds averaged 0.002 MIPS. Only a handful of the world’s largest corporations could afford the million-dollar price tag for the twenty-nine thousand pound device that filled a four hundred square-foot room.   UNIVAC was the device that coined the term “real-time” defined as the “actual time during which something takes place” plus a few more MIPS for processing.   No doubt, the technological breakthrough was amazing, if only visible to a few persons.

However, compare UNIVAC’s real-time stats to the iPhone 6, weighing in at less than five ounces, and fitting easily in a jacket pocket. In a sixty year span, the speed of real-time has increased by nearly 130 million percent. Ludicrous speed! Moreover, smart phones are ubiquitous. Now everyone can have real-time information, not just a few large corporations. So what’s so ludicrous about that?

From a Lean standpoint, there are a number of challenges:

  1. First, is the barrage of media presented to us every minute of the day. How many emails must I routinely delete each time I handle my smart phone?   How many videos do I need to see on, for example, Kanban? YouTube lists 56,600 entries. Which of these is valuable to me? Which represent misinformation?   How can I confirm? In reality anybody can post any video today – with ludicrous speed.  No doubt, some of these videos will be excellent. But I could sort and sift through the YouTube haystack forever looking for good information.
  2. Second, the promises of automating Lean are alluring but insidious. For example, say some, do away with those pesky cards (kanbans) and replace with them with real-time kanban. This, unfortunately, separates the information from the material, assuring that the two flows will be out of sync. Moreover, the ‘instantaneous’ information becomes invisible.   Cyberspace is not a Gemba. We can’t go there to see queues or delays or problems.
  3. There is a paradox in the lack of connectedness that has derived from this ludicrous speed of information flow. An increasing number of persons labor under the delusion, for example, that texting is “talking to someone.”   At a time when we are finally acknowledging the importance of social science to real Lean transformation, we are at the same time interposing a tool that isolates people, that creates only the illusion of human interaction.
  4. The ludicrous speed with which we can all whip up professional-looking presentations today has blurred the distinction between looking good and being good. In the immortal words of Dave Lee Roth, “It’s not whether you win or lose, it’s how good you look.”   PowerPoint, the original “baffle-them-with-B.S.” application has been around for twenty-five years, but it is quickly being supplanted by a plethora of smartphone apps for 5S, standardized work , Kanban, Kamishibai, and..well…you name it! Why do we do this? Because we can.   The words of my old-school TPS teacher are ringing in my ears.   Responding to my PowerPoint-drawn value stream map, he replied “Don’t make it pretty, make it accurate.
  5. Finally, as with material flow, when we focus primarily on cycle time, those nanoseconds of computer processing and transmission, we lose sight of the often huge stagnation time of computer queues, the automated over-production of information (produced before it is needed), and the total elapsed time for information flow, which includes the batching of information before input and after output. Those times can be truly ludicrous.

I’m admittedly a participant in the information age and I benefit from its ludicrous speed.  I use the Internet, for example, to write my posts and revel in the opportunity to pull in links to humorous video, historical background and scholarly articles.   But I worry that the ludicrous speed with which I send and receive information today may not be leading to more wisdom.

Please share your thoughts. Do you agree or disagree with the challenges I’ve posed? Can you think of other challenges?

P.S. GBMP has lined up several Shingo Institute workshops this winter and spring. For those who wish to learn how to create and lead sustainable cultures of excellence based on the Shingo Model and its Guiding Principles, we hope you can join one of our exceptional Certified Facilitators at an event near you soon. Read all about the courses and our faciliatators here.

Also, it’s long been a part of my organization’s mission to help build a community of passionate lean practitioners, leaders and learners and we at GBMP are proud of our Membership Mission and program. You can read all about it here. After more than a decade without a change in the annual fee to belong (which has always been an astonishingly low $495 per year for a company-wide membership),  dues are going up in March of 2016. Not without additional benefits, we promise. And not without the option to pay the current price to keep the current level of benefits (plus a few new ones). Beat the increase by signing up for or renewing a current membership now so you’ll get all the benefits of our GOLD Membership for the old price.

Up, Back and Around

up backWatching the US Women’s Team take the World Cup last week caused me to reminisce about my short-term coaching stint of a U12 soccer team. Before becoming a coach, I hadn’t played soccer or even watched a game, but there were not enough coaches in our town league so I volunteered.   After a two-week clinic for new coaches, I’d learned enough to know when I was allowed to substitute players, what was meant by off sides and a few other key rules. I’d even learned how to clumsily dribble and pass, but, like many other coaches, not well enough to actually teach the kids.  Fortunately for the team, however, a parent of one of the players knew John G., a local resident who at one time had played on the Portuguese national team. John seemed to know everything about soccer from basic skills to game tactics and even strategy for the season. Beyond this, John motivated and energized the kids. His personal enthusiasm and love of the game was contagious. Whenever I would thank him for sharing his skill and experience, he’d humbly respond, “The game is the best teacher.”

“No doubt,” I thought, “the boys are learning to play by playing, but John G. observes each boy’s every move, making subtle adjustments in skill and teamwork.”

Practice, after all, does not make perfect; it makes permanent. John had the boys practicing dribbling, passing and kicking the right way. Over the course of the season, every player improved individually, and the group of giggly eleven year old boys became an accomplished team – not World Cup, but pretty darned good.   “Better teams beat better players,” John G. exclaimed when any player appeared to be less than selfless in his play. Along the way I also became a better coach observing and listening to him.

Watching the superb play last week by the US women reminded me of one more of John G.’s lessons, which like his other coaching tips have had direct application to my work. “Up, back and around” he’d shout to the field during scrimmage. “Don’t always try to beat the defender directly. If the resistance is too great, then pass the ball back to your teammate and play around the defense.” While this tactic appeared to be “two steps forward and one step back,” it led ultimately to many goals.

So it is approaching True North.   The goal does not change, but depending upon the resistance at any point we should take John G.’s advice and avoid forcing the play. Don’t try to change the status quo by yourself. Share with your team members, and take the change up, back and around.

Do you trust all of your team, or do you only pass to certain team members? Let me hear from you.

P-D Ratios

The last few weeks have been all things Shingo for me including a presentation at the Shingo Institute’s International Conference three weeks ago in Provo, Utah, followed by four days of Shingo Institute workshops at Vibco in Richmond, Rhode Island. Questions at both events about assessing for enterprise excellence caused me to reflect on a basic framework that Shingo himself used to explain the progression of what we refer to today as “Lean maturity”.

pdratioThe P-D Ratio was Shingo’s comparison of the time required to Produce a product to the time given by the customer to Deliver the product. A large P-D ratio, for example, was indicative of a producer who took much longer to produce a product than desired by the customer. In 1985, this was the condition in my business. We attempted to match the customer’s short “D” time by stockpiling inventory.   Our push production method, as Dr. Shingo called it, was “speculative”, that is to say we built to forecast. Unfortunately our forecasts were wrong much of the time and there was an abundance of Muda in our production system. The atmosphere in the plant was one of frenetic expediting, particularly at month and quarter end. I don’t recall using the word “culture” at the time, but in today’s terms we did not yet have a culture of improvement. Shortly after I took a job as materials manager, a question posed to me by a buyer from one of our largest customers, a compressor manufacturer, summed up our P-D ratio:

“Welcome to your new job, Mr. Hamilton.   Can you explain to me why your company takes sixteen weeks to fill an order for a product the size of my fist, while my company can make a product as big as a house and deliver it in a week?”

That mortifying question may very well have been the trigger for my first study of TPS. A read of Robert Hall’s Zero Inventories (1982) led via a footnote to Shigeo Shingo’s Study of the Toyota Production System (1981) and this is where the epiphanies began. The book was such a bad translation from the Japanese that it has become a collector’s item. (It was retranslated in 1989 to a more readable but less authentic form.) Using Shingo’s ideas, we began to shift our production from “speculative” to “authorized” – Mr. Shingo’s words to describe the shift from push production to pull. And little by little, the sixteen weeks reduced to ten and then five and eventually, over a period of years, to two weeks for our customer’s product. With starts and stops and lot of TPS learning opportunities, by 1990 we’d reduced the P-D ratio from 16:1 to 2:1, not exactly just-in-time, but improved enough to be recognized in 1990 by the Shingo Prize for Manufacturing Excellence.

By the fall of that year we were asked to tell our TPS story at the annual AME conference in Boston.   A team of seven persons from my company each told a piece of the story: what we’d learned technically and how we worked together to overcome challenges and develop an improvement culture. After our presentation, each team member sat at a different lunch table, anxious to hear from other participants. As I seated myself for lunch, the gentleman to my right was already talking about some impressive results: shorter lead-times, inventory reductions, lower costs. Not to be outdone, someone across the table talked about same day delivery.   Another told a story of enormous cost reductions. “These are really impressive results,” I thought to myself.

I broke my silence by announcing that while my company had worked very hard to improve, our results were not nearly so compelling as those described by others at the table. Hoping to capitalize on the experience of others at my table, I then asked, “What companies are you with?”  To my complete surprise, everyone else at my table was a consultant. One was pushing Theory of Constraints, another was into TPM and a third was an MRP consultant. The rest were Lean consultants, a relatively new idea at that time. All had business cards in hand. Suddenly their improvement claims seemed a bit less credible. In 1985, there had been almost nothing written about TPS and the only Lean (TPS) consultants were from Japan. It was hard to find companies that had even heard of TPS. But, by the 1990 AME conference, Lean consultants were apparently multiplying like lab rats.   The group at my lunch table outnumbered the doers by 9 to 1, a ratio that was later borne out more generally by other of my team members. “Lean is good business for consultants,” I skeptically thought to myself, “but what about their customers.”

pdratio2Revisiting Shingo and his ideas over the last few weeks at conferences and training, I’ve concocted a whimsical P-D ratio for us to keep an eye on: The ratio of Pundits to Doers. (Yes, I am now a Pundit too.)   Today’s pundits have titles superior to consultant: Lean Expert, Lean Practice Expert, Sensei, Master Sensei, Black Belt, Guru and so on. Have a laugh –  We’re even on Weird Al’s radar!   My unscientific application of this Pundit-Doer ratio leads me to believe that while there are many more Doers now than in 1990 (the good news), the Pundit-Doer ratio is getting larger (the bad news.)  There are more of us, both internal and external, than there are doers.

During a recent discussion with my board of directors, the question was posed: “What do we want GBMP to look like in ten years?” One astute board member commented, “Perhaps we should ask ‘What do we want our customers to look like in ten years?’”

Where is your company on Shingo’s P-D scale?   Where do you want to be in ten years? Please share a thought.
