Not everywhere. But at your non-bottleneck operations, absolutely.
Here's why. Every system has one constraint that sets the pace โ one machine, one process, one person. The whole operation moves at that speed no matter what you do everywhere else. ๐๐ญ'๐ฌ ๐ ๐๐ก๐๐ข๐ง, ๐๐ง๐ ๐ญ๐ก๐ ๐๐ก๐๐ข๐ง ๐ข๐ฌ ๐จ๐ง๐ฅ๐ฒ ๐๐ฌ ๐ฌ๐ญ๐ซ๐จ๐ง๐ ๐๐ฌ ๐ข๐ญ๐ฌ ๐ฐ๐๐๐ค๐๐ฌ๐ญ ๐ฅ๐ข๐ง๐ค.
So when you push a non-bottleneck machine to run at 100% because idle equipment feels like waste, what happens?
Work-in-process piles up. Inventory goes up. Operating expense goes up. And throughput โ the actual rate you turn work into money โ doesn't move at all.

Inspection only means something if the thing you're inspecting against is right.
A CMM is a very expensive way to confirm a part matches a drawing. If the drawing is wrong, incomplete, or out of date, all that machine does is give you confidence in the wrong answer.
This is why quality problems so often trace back upstream to documentation rather than to the shop floor. The operator ran it right. The inspector checked it right. The spec was wrong.
Real quality assurance is a chain: correct drawing, correct process, correct measurement. Miss the first link and the other two don't save you.

That's the whole thesis of my ๐
๐๐๐๐๐๐ ๐ฌ๐๐ฌ๐ฌ๐ข๐จ๐ง, and it's the bet our entire company is built on.
Here's why I believe it. Every system has one constraint that sets the pace for everything else. On the shop floor that's usually a machine. At the company level, for most small manufacturers, it isn't a machine at all.
It's whether people are trusted to own outcomes or just execute tasks. Whether improvement is a project or a daily habit. Whether leadership development gets budgeted like capital equipment or squeezed in when there's time.
Fix the machine and you get a faster bottleneck. Fix the culture and you change what the company is capable of.
I'm unpacking the full framework in Vegas this October. ๐๐จ๐๐ ๐๐๐๐๐๐๐ ๐ ๐๐ญ๐ฌ ๐ฒ๐จ๐ฎ ๐๐% ๐จ๐๐ ๐ซ๐๐ ๐ข๐ฌ๐ญ๐ซ๐๐ญ๐ข๐จ๐ง, link in the comments. ๐

Thank you to everyone who helped make the Future Makers: Advanced Manufacturing STEM Experience a meaningful opportunity for students from Hazelwood East Middle School and Rogers Middle School - Affton.
With support from Big Rocks Engineering and partners including Greater St. Louis Area Scouting, Project Manufacturing, Southwestern Illinois College, and Missouri University of Science and Technology, students had the chance to explore advanced manufacturing in a hands-on, approachable way.
Opportunities like this help young people connect classroom learning to real careers and begin to understand that manufacturing is not just something that happens somewhere else, but rather right here at home.

It's been running for fifteen years. One supplier makes it. Nobody remembers who designed it. The only drawing is a photocopy of a photocopy with a handwritten change in the margin from 2011.
And it works. That's the problem โ it works, so nobody touches it.
Then the supplier retires, or raises the price 40%, or has a quality escape and suddenly that part is the only thing standing between you and a shipment you can't make.
The time to document that part is now, while everything's calm and you have a good sample to work from. Not during the emergency.
If you know exactly which part I'm describing, ๐๐ข๐ฅ๐ฅ ๐จ๐ฎ๐ญ ๐ญ๐ก๐ ๐๐จ๐ง๐ญ๐๐๐ญ ๐๐จ๐ซ๐ฆ ๐จ๐ง ๐จ๐ฎ๐ซ ๐ฐ๐๐๐ฌ๐ข๐ญ๐. That's the one we should start with.

Here's the argument I'm making. Most small manufacturers think they're losing to bigger competitors because of capital. Better equipment, deeper pockets, more people. I don't think that's it.
I think culture is the constraint. And unlike capital, culture doesn't require a bigger budget. It requires a framework and the discipline to run it weekly.
This isn't theory. It's what we run across five companies at Big Rocks Manufacturing, and I'll walk through the actual frameworks, not a case study with the details sanded off.

Grateful for a room full of people who show up, pull up a chair and actually talk. The conversation went everywhere it should. Excitement building for IMTS this week. The continued uptrend in manufacturing demand. Real talk on AI, ERPs, and actually using the technology on the floor instead of just talking about it.
And then the stuff that makes these nights worth it, like swapping stories about San Francisco, hiking Yosemite and Sequoia and somehow ending up deep in the history of the Norton grape and Napa Valley (if you know, you know, go read The Wild Vine).
That's the point. People who do the same work, facing the same challenges, just talking it out over a cold one.
Thank you to everyone who came out and made it what it was. These nights don't work without you and every time, I leave reminded of how good this community really is.
Haven't made it out yet? Join us for the next one on October 8th. The door's always open, and the first cold one is on us. ๐บ
