Ninety eight percent of technical trials are a lie told by a single focused mind and we all choose to believe the lie because the alternative is to admit that people are the only thing that matters. I sat in a room three weeks ago and watched a project manager show a slide with a big green check mark and a number that said one hundred percent.

They had tracked sixty seven crates from a dock in one city to a warehouse in another and every single tag had talked to every single reader and the data was as clean as a new sheet of glass. The board cheered and the CEO smiled and they all thought they had bought a solution but they had really just bought three weeks of a very smart man named Greg.

The Variable That Makes the Math Work

Greg is a senior engineer with a house in the suburbs and a desk that is always clean and he cares about things like the dielectric constant of corrugated cardboard. When Greg ran the pilot he walked down to the loading dock and he stood in the heat for five hours and he personally placed every single tag on every single crate.

He knew that if he put the tag too close to the steel corner of the crate the radio waves would bounce and die so he measured four inches from the edge with his thumb. He knew that the wet wood of the pallets would soak up the signal like a sponge so he made sure the tags faced the aisle and he cleared the path for the antennas. Greg was the variable that made the math work and Greg is the one thing they cannot buy in bulk for the rollout.

The Rollout and the Rule of the Thumb

The rollout started in September and the weather was grey and the mood was different. Greg was back at his desk working on the next big thing and the job of tagging twenty thousand crates went to a team of eleven people who were paid by the hour and had never heard of radio frequency physics.

They were given a box of stickers and a goal to finish by five o clock and a supervisor who told them to keep the line moving no matter what. By the end of the first week the read rates had dropped to seventy two percent and by the end of the month the whole system was a ghost of its former self.

The tags were the same tags and the readers were the same readers and the software was the same software but the knowledge was gone and the system was failing because nobody had written down the unwritten rules of the thumb.

The Failure of Presence

I spent a lot of time thinking about this while I was at a funeral last week and I did something terrible and I laughed out loud when the priest called the man in the coffin by the wrong name. The priest was just reading a sheet of paper and he was tired and he had three more services to do that day and he had never met Leonard so he called him Larry.

It was a failure of the rollout and the ritual was the pilot but the human in charge was just a part of a machine and I laughed because the absurdity of it hit me like a physical weight. We build these huge structures of technology and we expect them to carry our intentions but they only carry our presence and when we walk away the structures fall apart.

Dreams vs. Reality

The physical layer of a project is the only thing that is real and it is also the thing that people try to ignore the most. They want to talk about the cloud and the data and the analytics but all of that is just a dream if the tag on the box cannot scream loud enough to be heard.

“It is like building a multi million dollar radio station and then giving the host a tin can and a string.”

I have seen companies spend six figures on a software platform and then buy the cheapest stickers they could find on the internet because they thought a tag is just a tag.

Designing for the World That Kills

A tag is a complex piece of engineering that has to survive a world that wants to kill it. It starts in a factory where a tiny silicon chip is bonded to an antenna made of copper or aluminum. This bond is the heart of the whole thing and if it is weak then a little bit of vibration or a change in heat will snap it and the tag will go silent.

The team at

WXR

understands this because they have been inside the architecture of the chip since 2008 and they know that you cannot design a tag in a vacuum.

You have to design it for the substrate which is just a fancy word for the thing you are sticking it to. If you are tracking car parts you need a tag that can handle metal and if you are tracking bags of IV fluid you need a tag that can handle water.

The Transition to the Floor

When you move from a pilot to a rollout you are moving from a world of care to a world of speed and the hardware has to be strong enough to handle the transition. If the tag only works when Greg places it with his thumb then the tag is a failure even if it has a one hundred percent read rate in the trial.

A good tag is a tag that works when it is placed upside down by a guy who is thinking about his lunch and has been standing on concrete for eight hours. It has to be tuned so the frequency stays stable even when the environment is messy and the placement is sloppy.

The Value of the Boring Solution

I used to think my job was to find the most clever way to solve a problem but now I think my job is to find the most boring way to make a solution that cannot be broken by a tired person. I stopped looking at the best case scenario and I started looking at the worst person on their worst day.

I want the tag that works when the box is wet and the forklift is moving too fast and the worker is angry at his boss. That is where the real value lives and it does not live in the champagne emoji in the project channel after a successful trial with forty cartons.

Building the Genius into the Metal

The gap between the engineer and the temp worker is the graveyard of most IoT projects and you cannot bridge that gap with more meetings or more training. You bridge it by making the hardware so good that it does not need a genius to install it.

You design the antenna to be wide and the adhesive to be aggressive and the housing to be tough. You take the rules that lived in Greg’s head and you build them into the physical shape of the tag itself. If the metal frame of the crate is the problem then you build a tag that uses the metal as a part of the antenna instead of fighting against it.

The Hand That Decides

I saw a guy yesterday at a warehouse who was slapping stickers on plastic bins and he was doing it so fast that his hand was a blur. He was not looking at where the stickers landed and some were on the side and some were on the bottom and some were half hanging off the edge.

“I asked him if he knew what the stickers did and he said they were for the computers and then he kept moving.”

That man is the king of the rollout and his hand is the hand that decides if the project succeeds or fails. If the technology cannot survive his speed then the technology is just a toy for engineers to play with in a quiet room in March.

We have to stop treating the pilot like a proof of the system and start treating it like a test of the staffing. If the only way to get the data is to have a senior engineer on the floor then you do not have a system and you have a very expensive hobby.

The real work happens when the lights are low and the experts are gone and the machines are running at full tilt. That is when you find out if the tag you bought is a real tool or just a lie you told yourself to get a budget approved.

The Mercy of the Work

I still think about Leonard and the priest who called him Larry. It was a small mistake but it changed the whole meaning of the moment for everyone in that room. It reminded me that the hand that holds the paper or the hand that holds the sticker is the most important part of the whole chain.

We can build the best chips and the best antennas in the world but we are still at the mercy of the person who shows up to do the work. The only way to win is to make the work so simple and the hardware so robust that the name on the paper does not matter and the tag on the box speaks for itself no matter who put it there.

I have made this mistake myself many times and I have stood in front of clients and promised them the world because I saw it work in a small room. I forgot that the world is bigger than a small room and it is much messier and it is filled with people who do not care about my project.

I learned to love the physical reality of the factory floor and the grime of the loading dock because that is where the truth lives. You can keep your clean desks and your perfect slides and your green check marks.

I will take the tag that survives the hand of the man who is thinking about his lunch and the worker who is just trying to make it to five o clock. That is the only thing that is real and the rest is just a dream that ends in September.
