I get my kicks from Champlain

Samuel de Champlain is my nomination for Mr. Gemba.

I enjoyed immensely reading David Hackett Fischer's biography of the father on New France called Champlain's Dream (Simon & Schuster, 2008).  Like many of us in modern organizations, Champlain started out with a dream, had little if not negative "management" backing, did his exploration the right way, and changed his corner of the world forever.

Champlain's Dream
Let me put this in a QFD context.

Business Goals: converts Native Americans to Catholicism (as measured by # souls), create wealth for France (as measured in livers – French currency at the time), compete with English and Dutch (as measured by # ports, colonies).

Key Stakeholders: 3 successions of King Henri IV, Queen Regent Marie de Medici, and Louis XIII and their administrations. Financial backers including Compagnie de Caen and Hundred Associates.

Key Customers: various tribes of Native Americans on the St. Lawrence River, French traders, Colonists, Catholic Church clergy.

Customer Process Models: Champlain joined many tabagie (smoking festivals and meetings) with Native Americans to learn about their lives, their joys, and their struggles.

Gemba: After the "interview" research of the tabagie, Champlain then explored the St. Lawrence gemba. They joined hunts for food, parties of war, lived in their villages, ate their food, stayed on through the winter seasons (in the early 1600s, most Europeans were fair-weather visitors to North America). He did youth "student" exchanges to learn their languages and customs, etc. This is real gemba.

Customer Needs:

    About the Native Americans, Champlain learned:
  • Help feed our families (many St. Lawrence tribes were hunters and gatherers, did not store food, and suffered terribly with disease and starvation during some winters).
  • Protect us from our enemies (both Indian and European).
  • Help us live in peace.
    About Colonists:
  • I want to serve my King.
  • I want to become a land owner (almost impossible for non-nobility in France).
  • I want a place to retire with my family.
  • I want a great adventure.
  • I want to get out of debtors prison.
    About Clergy:
  • Establish the Church in North America.
  • Create a rule of law and faith (not just revenge).
  • Free to do missionary work.
    About French traders:
  • I want to trade with everyone.
  • I want to fish anywhere.
  • I want to make a lot of money.

Functional Requirements: respect for Native American cultures, no retribution, assure adequate food and nutrition, establish rule of law based on just solutions for all parties, build trust by keeping promises, religious tolerance, make colonies self-sustaining, encourage intermarriage.

The result was a mastery of exploration, cartography, co-habitation of peoples for mutual benefit, and a tremendous leadership style that got it "right" most of the time. This came from Champlain's non-judgmental willingness to learn, appreciate diversity, and explore beyond his comfort zone. In that era, it was the French who recognized the humanity of Native Americans, while the Spanish were enslaving them and the British were pushing them off their land.

Champlain's life is an example of how to do gemba right.

Now’s the time!

It’s that time of the year again, when we begin the call for papers for this year’s QFD Symposium.

This year’s will be an International Symposium, taking place September 6–7 in Santa Fe, New Mexico.  It’s a great time to meet your peers of QFD as well as greet some of the gurus of quality excellence.

As usual, there will be classes, discussions and demonstrations, and we’re looking for contributors who would like to show others how they’ve successfully applied QFD to their own professional (or personal) projects.

If you have a project or paper, completed or in-progress, you’d like to share, please send an abstract now.

Healthcare optimization and its effects on patients

This came from someone who read our recent post on healthcare improvement:

I would like to talk about a recent experience I had at a doctor’s office. Given my medical history, the experience might not be relatable to everyone but I think it highlights an important problem in the area of medical process improvement, where offices are adopting new Standard Operating Procedures to streamline patient visits, as a local improvement without seeing the big picture or global improvement.

(photo of an eye clinic)

To start, it’s important to note that I have a long history with eye doctors and have spent my whole life in the same medical system and hospital, and I have a medical record that could rival Proust’s In Search of Lost Time as a blunt weapon.  Like any experienced patient, I know the procedure for checkups and I know how my eyes should test.

On this visit, I made it quickly from the waiting room to the exam room (an area this hospital has made incredible strides in over the past twenty years) and soon my exam was underway.  The technician measured my eyesight with a multi-line letter chart and then took my eye pressure using a Tono-pen.  Both of my readings were off.

The multi-line letter chart helps prevent cheating through memorization but it makes it much harder to focus on any one line.  Tono-pens are used because they save time over traditional Goldmann tonometers (the little blue cones they press into your eyeball) but they are both less accurate and less precise. We’ll get back to the time savings in a minute.

My vision was measured at 20/30, acceptable for many people and good for others. But with my glasses, 20/15 is the norm and 20/20 is what I have on an off-day when I’m tired.  It’s not a big delta though and it can vary with things as simple as room dryness or the cleanliness of my glasses, so I was a bit annoyed with the result but not yet concerned. Then came the Tono-pen.
 
Tono-pens are a small handheld device for measuring intraocular pressure and they’re a godsend for measuring small children and patients who can’t sit still.  Unfortunately, I’m not one of them and given my eyes’ history, I have a very precise range of what my eye pressures should be. This particular visit, the pressure in both eyes was abnormally high by more than five; the right eye’s being nearly double its normal value and a possible signal that something might be wrong.  The technician’s response was to move me back into a waiting room while my eyes dilated, and advance to her next patient.

All of this was done in a matter of minutes and her efficiency was through the roof!  By basic metrics, she did her job swiftly and followed exact protocol for processing patients.  After all, it’s not her fault my eyes had subpar measurements; the doctor would just have to treat it.

When my doctor arrived, she began a more thorough investigation of my eyes. Her conclusion was that everything looked great.  All of the parts in every sector had maintained their shape and size from the last visit, and there wasn’t a hint of inflammation.  Still slightly worried about the high pressures, I asked if she could re-measure them and she obliged, this time using the gold standard Goldmann tonometer (photo below). This time, everything was normal.

(photo of Goldmann tonometer, photo by Jason Ruck, Creative Commons)

The point of this writing is not to call attention to a single technician, because she did exactly as she was trained.  It is rather to show what generic service can miss and how it could be better.

Upon seeing and hearing that my eye pressures were out of line, the technician should’ve conducted a second test, possibly using the more accurate and precise equipment, and compared it to my historical figures. The problem with this is that it would’ve cost her time, and being in a low level position, she doesn’t have the clout to shrug off time requirements and quotas.

Now why is it a problem if everyone in a medical office tries to work as quickly as possible? 

Mistakes and malpractice aside, it misses the big picture.  The primary bottleneck in a doctor’s office is the doctor herself.  They are in least supply, have the busiest schedules and are almost always the reason you’re processed in a timely or slow manner; the rest of the system adjusts around them.

In this case, spending an extra three to five minutes during the technician’s stage would not have delayed my consultation or departure at all, since I still had to wait another 5+ minutes for my eyes to dilate and another 5+ after that for the doctor to become available.  The same goes for the next patient she had to visit.  If the doctor can only see 5 patients per hour and technicians prepare 10 patients per hour, the clinic will still only fully process 5 patients per hour.  The system can move no faster than the slowest link.

So not only did the time saving measures before the doctor’s stage provide no temporal benefits but in the end, the less precise device actually cost the clinic time it was meant to save.  You see, the doctor spent additional time conducting a re-measurement of my eye pressure that actually could’ve taken place twenty minutes prior when there was a buffer zone.  Reducing time during the technician’s stage meant overloading the doctor’s stage and the end result was an increase in the total time for processing.  As you can imagine, this sort of thing gets compounded with every patient.

In the late Eli Goldratt’s Theory of Constraints, it was recommended improvements to throughput must come by way of removing all unnecessary loads from the bottleneck. At a clinic, this means that anything that can be done by a technician should be done with the precision and accuracy that a doctor requires so that they do not have to repeat testing. By increasing the attention to detail of technicians, it may be possible to reduce the overall load on the doctor, thus speeding up the entire system.  This could add up to significant savings, especially in these times of concern for reducing healthcare costs for both hospitals and patients.

What ever happened to customer service?

It seems these days that customer service has gone to the dogs. It used to be we gave our best customers our best service, especially in this service economy! Here are some of my recent experiences.

(photo of restaurant check holder)
Case #1
At a national chain restaurant
, the guest check holder (the leatherette bill holder the waitperson brings to your table) was redesigned. Instead of the conventional, little clear plastic pocket that was the perfect size to hold a credit card, their new design has a simple slit that is cut directly on the holder lining.
    Because there is no pocket seam to hold the card securely in place anymore, once you insert the credit card into the slit, gravity works to slip right down to the bottom of the 10" deep holder, unbeknown to the customer.

    When my waitress brought my credit card slip to sign, the card was nowhere to be seen. After a frantic search of the floor around the table, the card was found stuck inside the lining of the folder where it had slipped down to the bottom. It had a friend, too – another card lost by a previous guest over one week prior! The waitperson's response – "Oh that happens all the time." Well, if it happened more than once, why didn't they fix the problem?

    Case #2
    The new US healthcare laws require that children over 26 have their own health insurance. After transferring our son to his own insurance plan, he enrolled in automatic-pay from the bank account. The first monthly payment was deducted properly, but not the second. After several long phone calls, it turns out the second payment was deducted from someone else's bank in error. How could that be, since it's all done by computer, right?

    In fixing the problem, the insurance company not only removed the incorrect payment for the current month, but they also removed the correct payment for the previous month, meaning my son was now in arrears and at risk of losing his new insurance, even though we had followed all correct steps to transfer and set up automatic payment.

    Furthermore, their customer service representative just reported his account now shows "paid" for the next five months, even though he has not paid past the current month.

    Case #3
    (photo of smart phone roaming)
    "Global roaming" on a mobile phone is essential when traveling overseas. I recently had to activate the plan that gives me a discount on data when traveling abroad, which is important for a smart phone. Well, this took several calls with conflicting information from the various agents at my mobile service provider. One person said it was not necessary, another said it could be done now and I would be all set. A third person actually took me through the steps to change my iPhone settings so it would work. Had this third person not explained the setup to me, the phone would not have worked.

      I'm sure you must have some stories yourself. Why not share them with us?

      If you run a service or support operation, learn how to understand what your customers really want. It will earn you customer loyalty and save you money from multiple mis-handlings by your staff.

      To learn new QFD tools for this, I recommend attending the QFD Green Belt® course. I will be teaching the Orlando course on Feb. 28 - March 1, 2013. You will learn how to apply QFD correctly and most efficiently from the first time.

      The course includes Excel templates which is an economical alternative to buying commercial software that is most likely based on outdated methods. The course has no prerequisites.

      “Did you find everything okay?”

      It’s a question consumers hear on a daily basis, whether they’re at a grocery store, electronics store, sporting goods store or basically any kind of retail outlet.  Sometimes our answer is ‘yes’ and other times ‘no,’ but what never seems to change is the outcome from this little encounter.  Anyone reading this blog probably already understands why – because it’s not a service question, it’s a marketing statement.

      (photo - cashier and customer "Did you find everything okay?")Much like “Welcome!” from greeters at many mega stores, this simple line is meant to project a customer-first attitude amongst a store’s employees (and at no additional cost!,) however, unlike a throwaway greeting, this question represents a much greater missed opportunity.

      It is not that the asker (often a cashier) is disingenuous when asking this question, but rather the question itself is problematic and their training does not enable them to deal with the voices of customers they receive.  It is an avenue for feedback, but it almost always leads to a dead end.

      The most immediate problem with this question is that it’s vague and open to multiple interpretations by different customers.  One of the main principles of asking good questions is making sure the respondent actually knows what’s being asked.

      The first possibility that springs to my mind is, “Was the process of finding specific product groups and making selections easily accomplished?” This can be broken down in at least three ways as follows:
      • “Was our inventory organization logical to you?” 
      • “Was our inventory accessible to you?”  and 
      • “Did we provide enough information to help you decide?”  
      There are likely more ways to break down the process of shopping, but it’s worth noting that an online store like Amazon, which has begun to enter the grocery business in some cities, can easily meet these needs without much extra effort through their existing online interface.  This makes it all the more important for today’s brick and mortar grocery stories to satisfy in these areas.

      Another way to interpret the question is, “Do we carry the specific items you’re looking for?”  – either by item type or item brand. This is an issue of supply management and no amount of friendly customer service is going to help the customer get what they want on that current trip.

      There might, however, be an easy and visible method for customer requisitions, which would not only please a customer but also guarantee a return visit when their item arrives.  This is often possible at electronics stores (although the process is far from visible or easy) but is rarely possible in grocery stores.  When a customer’s favorite brand of mustard or bread goes missing and they ask an employee why they no longer carry that item, they’re often met with an “I don’t know” which is neither helpful nor informative. The excruciating weakness of that response is that it could be!

      Even when store representatives ask meaningful questions and their customers provide informative answers, they’re rarely trained with the necessary tools or provided a response channel to turn that voice of customer into helpful information.

      Every time the question is asked, a store is in position to receive useful feedback, both positive and negative, yet that information goes nowhere; it gets stuck with a clerk who doesn’t know who to give it to or a manager who doesn’t want to receive it. “Did you find everything okay?” is a façade of customer-first thinking, and fortunately there’re ways to improve it.

      An easy start is to ask better questions, and to make sure your representatives know how to respond when the customer's answer is “no.”  A working response channel from customer to representative to management is important, however this is dependent on a customer’s time, mood and memory and may lead to skewed results.

      For instance, feedback on message boards tends to occur more when something has gone wrong, rather than when something has gone right.  Questionnaires sent out by grocery stores tend to be focused on their own product or process rather than the customer’s experience (or their desired shopping outcome), and by the time customers receive them, they may not remember all of the relevant details from their shopping encounter.  Furthermore, even if a customer did have difficulty searching through a store’s shelves and a cashier was able to help them, what good would it do if the customer had already waited in line and was about to pay (as they often are when the question is asked)?

      For these reasons, going to the gemba is the most effective way to find customers’ needs in order to improve their shopping experience.  True customer-first thinking means discovering if they “found everything okay” (and everything it entails) before they check out of your store.

      When your EOB becomes an SOB!

      When is information from a service provider (or any vendor) too little or too much? I'd like to share a recent experience with my health insurance company.

      When It Is Too Little. 
      My university offered me health insurance on an "opt-out" basis, meaning I was included unless I chose not. The insurance would only covered me and not my family, so I did not want it. I missed the opt-out deadline, and unbeknown to me, I was added to the university policy, which used the same health insurance company as my family policy.

      This insurance company, seeing two policies under my name, automatically dropped my family policy. They did not call me, they did not write me; they just sent me a refund check in the mail.

      When I received the check, I called them to find out why – it was a refund of my family policy which has been in place over decades with no lapse in premium payment, and yet they decided to cancel it without ever asking me. Stunned and outraged, I had to buy a separate "bridge" policy for my family from a different insurance company.

      Eventually I was able to reinstate my cancelled family health insurance policy and get off the university plan, but it took a month of calls to both the insurance company and university and dealing with their bureaucratic processes before finally getting things straighten out.


      When It Is Too Much. 
      photo - Billing Statement
      Yesterday, my insurance company just sent me a revised EOB (explanation of benefits), about a hospital treatment from a few months ago, for which they had already reimbursed since then. I have the original hospital bill as well as the first EOB showing a balance of $0.00.

      However, the revised EOB I just received indicated that nothing had been paid to the hospital and that I was responsible for the full amount (it was expensive!).

      I called the insurance company and they explained these details: After the original bill was reimbursed, the hospital lowered their price (hospital billing error) and re-sent a smaller bill to the insurance company. This triggered the insurance company to "take back" the original payment and send me a revised EOB explaining nothing had been paid.

      Then, the insurance company paid the hospital the lower amount, and issued a "revised, revised EOB" showing that my balance was now $0.00 again. This revised, revised EOB will be mailed to me next week, they tell me. How confusing!

      In other words, in this case the insurance company, for some internal reason, decided to write to me the intermediate information that I did not need to know. Because of this intermediate and incomplete information, I became very worried and spent a lot of time, trying to find out what happened. It would have been better had they told me nothing and just handled the transaction between the hospital and the insurance company. SOB!

      Kansei Engineering and Education

      One of the "cousin" methods we use in Modern QFD is called Kansei Engineering, which I often translate as emotional quality (when used by itself) or lifestyle deployment (when combined with QFD).

      The original concept creator, Dr. Michio Nagamachi, also uses it for ergonomics (both physical and emotional) in order to elevate a produce above its pure functionality.


      In a January 5, 2013 article in the New York Times by Al Baker, "Ergonomic Seats? Most Pupils Squirm in a Classroom Classic", the subject of school chairs interested me greatly. It seems that even today, most schools see chairs as a means to corral children so they can learn in the traditional school settings that date back to the 19th century 5-S approach: sit straight, speak only when spoken to, study only the books we approve, store easily, and save money.

      photo - school chairs


      Saving money seems to still trump the others, as schools continue to buy chairs that will last 30-50 years. Despite a German study and recent experience that children's comfort and engagement are improved with more ergonomic and mobile chairs, schools are slow to change. Professor Galen Cranz in her 1998 book "The Chair: Rethinking Culture, Body and Design," wished child movement were accorded more consideration.

      From a QFD and Kansei perspective, children should be seen as "customers" and users of the chair.  Today's classrooms, group work, electronics, and other educational tools should be observed in "gemba" visits (actually go to a classroom and see how teachers and students interact), so that 21st century chairs and desks can be created to help children achieve their educational goals.

      I know observing children is problematic, and adjustments to the gemba methods must be made. You may find these papers helpful:

      Capturing voice of social network and using it

      Brian X. Chen reports in the January 2 2013 Bits section of the New York Times, "The iPhone Goofs Up on Telling Time, Again," that the new Do Not Disturb (DND) function on iOS6 iPhone failed to turn off for many users on New Years Day.

      This is a new feature that allows iPhone users to set a quiet time (like when you sleep) to block incoming calls and alerts. It is suppose to turn itself off at a pre-determined time so that calls, alerts, and alarms can be heard.This bug is even more noteworthy because it is featured in a new television commercial airing this week. NYT readers first blasted Apple for the bug, and then turned on themselves for whining about such a small inconvenience.

      This brings to mind two QFD concepts. The first is the famous "Sales Point" column in the quality planning table room on the right side of the House of Quality matrix (or done independently in Blitz QFD®) where a selling point is given extra weight which eventually strengthens the improvement calculation for related technical requirements. Below is one example of a HOQ with Sales Points weights (the yellow highlighted column).

      example - HoQ matrix (partial) with Sales Points weights

      The purpose of the "sales points" column has been frequently challenged as it seems to do the same job as the relative importance and the level-up columns, and is thus redundant. Dr. Akao's purpose, however, was to add a sales point value when the associated customer need is going to be promoted, as in the case of this Apple commercial. The added weight would direct engineers and software developers to  pay more attention to its auto on/off functionality.

      The second point, I commented myself back to the New York Times:
      "I see the DND issue as one of software quality. Developers often have incomplete or inaccurate use cases around which they design their features and code. They do not fully understand how the feature gets used in real life, and so sometimes get it wrong. Like the proverbial mushroom, they are kept in the dark and fed s**t!
      It is comments from users like you who post here that can provide the necessary insight to do the job right the first time. There are methods for analyzing the voice of the customer, like QFD, that actually build on your feedback and help marketeers and engineers do their jobs better. So keep on blogging and contributing your experiences - we will all benefit."

      My second point is that every opportunity to get customer feedback should be welcomed by a company. Many companies do monitor social media as part of their customer relationships management (CRM) programs, but not all companies forward the information to new product development departments.

      The customer voice table is the QFD tool for analyzing these comments. In order to give engineers direction for improvements and next generation products, negatives and complaints should be reversed into positive statements, and technical solutions should be translated into product independent customer needs.

      Why we drink beer?

      As we celebrate the various holidays and new year in our own special ways, let me propose a toast – of Singha Beer!
      photo - Singha beer

      This week, the American Society for Quality (ASQ) posted as an "Editor's Pick" on their Knowledge Center a QFD case study done by Singha Beer of Thailand. The response has generated a lot of interest and ASQ plans to post it on their home page.

      Unlike most QFD applications, this case had little to do with the product, and much to do with the marketing and branding message – not what we drink but why we drink.

      Here is the link to the article "Thai Brewery Deploys QFD Tools to Tap Into Consumer Motivation" (PDF) at ASQ site.

      Enjoy.


      PS: The QFD Institute also has a synopsis of this case study

      QFD at Holiday Time

      The holiday season is a great time to sharpen our QFD skills. Here are some techniques that might make the celebrations and shopping a little easier.
      photo - holiday gift shopping
      • Gift shopping for someone? Instead of asking them what your should buy (a solution), try asking for what they need (what difficulties do they have at work or home, what opportunities do they wish for, how would they like others to see them)? This helps us practice the Customer Voice table where we translate VOC into true needs.
      • Hard to choose among several options for a gift, a restaurant, or a party to attend? Practice your alternative selection technique.
      1. First list your options.
      2. Write down what is attractive about each option, and what is unattractive about each option. Convert unattractive statements into positive ones. For example, this restaurant is "too far away" becomes "nearby." These are your judgment criteria.
      3. Prioritize the judgment criteria. For emotional decisions, AHP's pairwise decision making is a great way to work through them.
      4. The highest priority judgment criteria will drive your decision. Look at which option best fulfills them. Feel comfortable that you made the best choice possible given all the wonderful options.
      photo - holiday party options
      1. Define your dilemma using the Engineering Parameters in Table 2 in the above link. For example, I am invited to two parties at the same time – my best friend and my in-laws. One contradiction is improve EP 26 Amount of Substance (I want to improve my pleasure for the afternoon) without the undesired result of EP 13 Stability of Object (I don't want my marriage to become unstable).
      2. Look up the pair in the Table of Contradictions to find Inventive Principles 15, 2, 17, 40. Let's see what solutions we can invent.

          IP 15. Dynamicity.
      1. Make an object or its environment automatically adjust for optimal performance at each stage of operation. Have the meal at your in-laws (so you can compliment her cooking) and dessert at your friends (so you can stay late).
      2. Divide an object into elements which can change position relative to each other. Same as above, but decide that day where to go first.
      3. If an object is immovable, make it movable or interchangeable. E-mail your suggestions to qfdi@qfdi.org

          IP 2. Extraction.
      1. Extract (remove or separate) a "disturbing" part or property from an object.
      2. Extract only the necessary part or property. Exchange gifts, have a drink at the in-laws and then see your friends.

          IP 17. Move to a new dimension.
      1. Remove problems with moving an object in a line by two-dimensional movement (i.e. along a plane). Invite in-laws and friends to your house, instead. Have one party upstairs and the other downstairs.
      2. Use a multi-layered assembly of objects instead of a single layer. Add pleasure to visiting your in-laws by inviting your friends to come with you. Or, have lunch with in-laws and dinner with friends.
      3. Incline the object or turn it on its side. E-mail your suggestions to qfdi@qfdi.org

      IP 40. Composite materials.
      • Replace a homogeneous material with a composite one. Take two cars, and divide the family up so each can stay as long as they want at either party.
