When my wife was seven months pregnant with our first child, we moved into my parents’ spare bedroom. We had just rented out our house, and we were six weeks away from closing escrow on our new home where we would go on to raise our little family. While we were living in the spare bedroom, we had to quickly adopt some survival skills. This was a great adventure, mainly because of me. I am not only a super-sensitive person, but I also think that I am funnier than I actually am...
To survive this six week adventure, my wife and I quickly realized that we needed a special “stop” signal that either of us could invoke without angering the other. We needed an alert system that, without words or sensationalism, indicated "feelings are about to be hurt." Living in such a small space with so much external stress, we needed to ensure that effective communication and systems were in place to end teasing, nagging, questioning, or eye-rolling before the point of no return. The signal? If one of us were about to experience hurt feelings, we were to extend our arms and close them shut, like the jaws of an alligator. This signal means, without question, hesitation, sarcastic remark, or huffy sounds, that everything was to stop. Immediately.
Almost a decade later while reading the book The Lean StartUp (2011) by Eric Ries, I was fascinated to learn about a mechanism at Toyota that worked in radically the same way. It is called the "Andon Cord." The Andon Cord is a cord that any worker along the assembly line is expected to pull if a problem or concern is seen. Pulling the cord is not something determined by rank or seniority. Pulling the cord illuminates a series of immediate responses by supervisors that may or may not actually stop the entire line of production. Ries (2011) explains that it "allows any worker to ask for help as soon as they notice any problem, such as a defect in a physical part, stopping the entire production line if it cannot be corrected immediately" (p. 187). Without naming it, in How (2011) by Dov Seidman, he explains the power of this concept as "it (quality) became the responsibility of every employee at every level of the task. Power shifted from the top of the hierarchy down to its base; anyone, at any stage of the process, could stop the line" (pp. 211-212).
This is much like what my wife and I had developed to get through our in-between-houses-time, and in fact we still use the signal today. Frankly, much of the success of our marriage has been forged by this strategy that puts the responsibility on both of us for acting and responding appropriately in a predetermined and understood fashion.
I was speaking to a visitor touring our school in the spring of 2017, and he took the story of the Andon Cord as a quality control tool and superimposed it as a strategy for ferreting out instruction that didn't meet “his” standards. In fact, he quite-excitedly gleaned that this proven concept from industry empowered him to be more direct and quicker to make note of low-grade instruction at “his” school.
So bothered by his interpretation, I was inspired to write this post. I told him that I thought the transference of the concept of the Andon Cord from manufacturing to education was more to do about empowering all people in the organization and flattening the hierarchy, aka, culture. It was not immediately about quality control on instruction. I told him that, in fact, I thought the story taken in the context as he processed it was actually damaging. Whether he wanted to hear it or not, I continued that, 'from my perspective, the power of the Andon Cord idea speaks to...'
