Going to Gemba

Source: Motor Trend (http://www.motortrend.com/news/miles-in-three-2013-honda-accords/)

In my past life before data architecture, I used to be a manufacturing engineer in the automotive industry. At the time, the popular approach was Lean Manufacturing and the Toyota Production System, driven by Toyota’s massive success in the United States.

Lean was—and still is—about increasing value to the customer by reducing and eliminating work that doesn’t add meaningful value. This spawned many tools and practices to surface inefficient habits. One that stayed with me was the concept of “going to gemba.” In Japanese, gemba means “the real place” where work actually happens. In practice, this meant that managers and engineers left the office and went to the shop floor. There they simply observed: stood and watched the work happening, and asked questions of the line operators in a curious and respectful manner. No decisions were made on the floor. Leadership took what they had learned back to the office and used those lessons to shape operational plans.

This concept came to mind as I read this post on LinkedIn:

Dirty Data (Done Dirt Cheap)

The running joke amongst Generation X is that we don’t listen to music after the year 2000. We feel comfortable around the music we grew up with, so we prefer to stick to the music of the 80s, sometimes the 70s, and occasionally the 90s. That’s true for me, although in my case, while my musical taste stayed in the 80s, over the years it’s wandered over the globe sampling music from the decade. When I was in Europe I caught the last few years of European synth pop and Italo Disco. When I moved to Europe it was Celtic rock with Clannad. And just prior to COVID I was digging Soviet rock through Kino and Victor Tsoi.

So we Gen Xers regard it with some bemusement when the younger generation start rediscovering the artists we grew up with. First it was Millennials getting rickrolled and finding they actually liked Rick Astley, leading the ginger crooner to come out of retirement. More recently, the backdrop of the 80s in the Netflix show Stranger Things brought many 80s songs back into the spotlight, such as Kate Bush, David Bowie, and Metallica. The series finale, which dropped on New Year’s Eve 2025, did it again. Prince and the Revolution’s “Purple Rain” re-entered the Billboard Hot 100 at No. 27, its first appearance on the survey since Prince’s death in 2016. “When Doves Cry,” the other Prince song in the finale, was the one new listeners had to look up. It topped US and UK Shazam on January 2, 2026, in part because the title is barely in the lyric.

The thing that most interests me, however, are the reaction videos. Sometimes, new ears notice things that mine have overlooked.

Fire for Effect

My unit: 3rd Battalion, 13th Field Artillery. “Without fear, favor, or hope for reward.” (Source: public domain media)

I went to college on an ROTC scholarship. When I got my degree, I went into active duty service as a lieutenant. During my time on active duty, I served in a field artillery battalion, as part of the operations staff. That is where I learned how the Army actually delivers fire support

The most important thing to know about artillery is that it can’t win the battle alone. The Army relies on maneuver units (tanks and infantry) to seize or hold the battlefield. Artillery supports them by putting shells, rockets, or missiles on the enemy to suppress or destroy it.

How that support is organized is the interesting part. Artillery units usually belong to a division or a corps, but they do not always work directly for that headquarters. Sometimes they shoot higher-level missions such as SEAD (suppression of enemy air defenses) or counterfire (attacking the other side’s artillery). Sometimes they talk straight to a subordinate unit that is in contact and needs rounds now. And sometimes they have a primary mission and a secondary one stacked underneath it.

The Stall

A while ago I was “gifted” with a gas grill. (It’s a long story—basically, someone I knew left behind the grill at my house and never came by to pick it up.) While I enjoy cooking, I’m usually not much of a grilling guy. However, I do have a fondness for barbecue. I lived in Kentucky for over two decades and traveled all over the South during that period. As a result, I was initiated into the finer details of pulled pork and smoked brisket.

As it turns out, there is actually a way to smoke with a gas grill; all you need is a smoker box to hold the wood chips, which you can get at any hardware store. So this past summer, I figured I’d put the gas grill to use and try my hand at smoking. It’s been a learning experience, and there were mistakes along the way. But with time and practice, I’ll get better at it.

Déjà Vu All Over Again

When I was finishing college in the early 90s, one of the trends that was starting to go viral back then was the concept of fractals. Although the term had been invented in the 70s by the mathematician Benoît Mandelbrot, it didn’t really take off in the public consciousness until about twenty years later, due in no small part to computer-generated graphics of the Mandelbrot set. Something about psychedelic imagery of Mandelbrot sets really clicked with the zeitgeist back then (largely thanks to boomers coming into their ascendancy and reliving some of their highlights from the 60s).

Ghosts in the Machine

*We are Spirits in the Material World (Source: “Betty Boop in Snow White”, 1933)*

Back in the 90s, while I was still on active duty, I joined a Compuserve online forum for active and veteran military members. I remember a post by an Air Force captain retelling an incident that happened in the skies over Iraq during Operation: Desert Storm.

This occurred during the initial combat missions while the Coalition Forces were establishing air supremacy. On one mission, the captain was flight commander for about half a dozen fighters. They were flying above the clouds when his wingman reported a radar contact underneath the clouds. The IFF (Identify Friend or Foe) transponders did not indicate that these were friendly planes, so his wingman recommended attacking (which, under the rules of engagement at that phase, was the correct response).

Something about the whole thing felt off to the captain. He instructed the flight to wait for visual confirmation.

Schrodinger’s Cat

I haven’t owned a television for the last fifteen years.

Call it an odd twist of fate, but I was gradually weaned off of television since college. A lot of people, especially in the younger generation, find the concept of life devoid of TV as inconceivable.

However, instead of television, I do watch a lot of YouTube, especially by independent content creators covering diverse fields such as pop culture, Slavic hardbass music, law, and cooking. And since the Amber Heard/Johnny Depp trial, I’ve been watching a lot of livestreams about the entertainment industry.

And one metaphor that’s been popping up lately is the analogy of Schrödinger’s Cat.

Running on Empty

At the lowest point in my life, I had less than twenty dollars to my name.

It was 2004, and I had been unemployed for nearly a year. Due to the circumstances under which I was terminated, I was denied unemployment insurance, forcing me to live on meager savings that ran out within a couple of months. I ended up selling almost all of my gaming and science fiction books and toys on eBay just to have money to pay the mortgage. As for food and gas, I did the dumbest thing you could ever do: max out my credit cards and play the balance juggling game to stay solvent.

It was so bad, I almost got arrested for bouncing a check on a speeding ticket.

Take the Long Way Home

For most people, 2021 will be remembered as 1 PC (post-COVID). Some people have spent this year resigning themselves to the New Normal. Others have been struggling to return to the Old Normal, life before social distancing, masks, and vaccines.

For me, however, 2021 was the watershed for the New Old Normal.

In this year that’s just ending, I left Kentucky, the place I had been living for half my lifetime, and moved back to New Hampshire, my childhood home. Since announcing my departure back in August, many people have asked what made me decide to leave. The answer I gave was simply, “After COVID, I decided it was time to come home.”

This works fine for small talk over cocktails. But much like the rest of 2021, the truth is much more complicated.

Sins of Our Fathers

Not too long ago, I happened to hear about an old friend from school. We had corresponded off and on for a while, but I hadn’t really seen her for over 18 years.

(Out of respect for her privacy, I’m not mentioning her name. If you’re reading this, and I hope you are, know that I’m writing this for you out of the best faith. Tough love is as hard on the giver as it is on the recipient.)
