The Governing Principles of Lean

The Three Governing Principles That Resolve Every Lean Conflict

Here’s the deal. Somewhere in every genuine Lean journey, you hit a moment where two real Lean principles seem to pull in opposite directions. Someone says, I want to eliminate this waste, but getting rid of it costs money. Someone else says, I see a genuine improvement here, but at what point does chasing it become wasting time instead. Those moments are not a sign Lean is broken. They are a sign you need a genuine tiebreaker, and there are three governing principles that consistently resolve these conflicts.

I want to be honest that I have not tested this exhaustively enough to claim it is complete, and this framework may keep developing as I encounter more edge cases. What I can say confidently is that these three have held up consistently every time I have actually applied them.

The First Governing Principle: Theory of Constraints

When two Lean principles conflict, the first question worth asking is simple. Is this actually your bottleneck. Theory of constraints is genuinely one of the biggest governing principles across all of Lean, and it works by asking which option actually addresses the real limiting factor in this specific situation, rather than which one sounds more theoretically correct in general.

Here is a real example. Our own CFO recently faced a genuine conflict between one piece flow, which would take more time, and batching a task, which would be more convenient but potentially risk quality on something legally sensitive that genuinely could not afford a mistake. The real question was not which principle sounds more Lean in the abstract. It was which one actually addressed her genuine bottleneck. Since quality was clearly her most limiting factor in that specific situation, the correct move was choosing the larger batch, even though that technically violated one piece flow, because it protected the thing that actually mattered most in that moment.

Notice what actually happened in that conversation. Nobody argued about which principle was more theoretically correct. The entire decision came down to one direct question, asked and answered honestly, about where the real risk actually sat. That is the whole value of leading with constraints first, it replaces a debate about ideology with a concrete diagnosis.

Watch for these signs theory of constraints should be the deciding factor in your own conflicting Lean decision.

• One option clearly addresses a genuine limiting factor, while the other option simply follows a general Lean rule without regard to what is actually constraining the situation.
• A real, tangible cost, financial, legal, or safety related, tied directly to getting the decision wrong in this specific instance.
• Two Lean principles pulling in different directions where only one of them actually touches the real bottleneck at hand.

The Second Governing Principle: Respect for People

This one requires less explanation, though it deserves just as much weight as the other two. When two Lean principles genuinely conflict, ask directly which option best respects the human beings actually involved. That question alone tends to cut through a surprising amount of theoretical debate quickly, because it grounds the decision in something concrete rather than an abstract rule.

The Third Governing Principle: Quality

Here is where this framework got genuinely interesting for me recently. A colleague identified a real opportunity to improve the build kits we send out for our own training bootcamps, and it ran into a different Lean principle, the general guidance to only use thoroughly tested software and hardware rather than experimenting with something new. That created a genuine conflict worth resolving properly.

The resolution came down to asking what our actual product is. Since our business genuinely depends on delivering a quality bootcamp experience, investing real, careful attention into getting those kits right was not wasted effort or unnecessary nerding out. It was directly serving the actual product we sell. Quality can never be good enough when quality itself is the entire reason people show up in the first place.

That decision led directly to a genuinely clever solution, organizing every kit so its contents are perfectly arranged inside their storage bins. That single change does more than one thing at once. It showcases Lean thinking directly to the people using it, and it creates a genuinely remarkable experience that makes people want to come back and tell others. Quality and respect for people were not actually competing in that decision. They were the same decision, viewed from two different angles.

That outcome is worth paying attention to, because it means these three governing principles do not always compete against each other in practice. Applied honestly to the same situation, they often converge on the exact same answer, which is a genuinely reassuring sign that the decision being made is actually the right one.

Watch for these signs quality should be the deciding factor when two Lean principles seem to conflict.

• The improvement in question touches the actual core product or service your organization exists to deliver.
• Client or customer experience is directly affected by whichever option you choose.
• Investing real effort here would strengthen the very reason people choose to work with you in the first place.

Why Having Three Governing Principles Actually Simplifies Things

None of this requires memorizing dozens of individual Lean rules and hoping they never contradict each other. It requires holding these three governing principles above everything else, and running any genuine conflict through them directly. Is this the actual bottleneck. Does this genuinely respect the people involved. Does this protect or strengthen real quality. Whichever principle answers most directly to the specific situation in front of you tends to be the one worth following.

This is also why the framework stays useful even as new, more specific Lean rules get added over time. Individual rules can multiply endlessly, and new situations will always surface conflicts nobody anticipated in advance. Three governing principles held consistently above all of them give a team a stable way to reason through whatever comes up next, without needing an ever growing rulebook to cover every possible case in advance.

Applying This Framework to Your Own Team

None of this replaces good judgment, and it is not meant to. It gives that judgment a genuine structure to work through, rather than leaving every conflicting decision to gut feeling or whoever argues most persuasively in the room.

If your project needs superintendent coaching, project support, or leadership development, Elevate Construction can help your teams build genuine decision making discipline around these three governing principles, so conflicting Lean guidance stops feeling like a contradiction and starts feeling like a genuine, resolvable question.

So here is the challenge. The next time two Lean principles on your own project seem to pull against each other, run the decision through all three governing principles directly. Is this the actual bottleneck. Does this genuinely respect the people involved. Does this protect or strengthen real quality. More often than not, one of those three will answer the question clearly enough to move forward with real confidence.

Jason Schroeder said it plainly: “What would the theory of constraints say? What is best for our people? What is best from a quality standpoint?” Run every genuine conflict through those three questions, and the path forward tends to become clear.

On we go.

FAQ

Why do Lean principles sometimes genuinely conflict with each other in the first place?

Because individual Lean principles, like one piece flow or eliminating unnecessary spending, are each useful guidelines in general, but no single guideline accounts for every possible situation. Real projects and real businesses regularly encounter specific circumstances where two generally sound principles point in different directions, which is exactly why a higher level framework is needed to resolve the tension.

Why does theory of constraints outrank a general Lean rule like one piece flow when the two conflict?

Because theory of constraints asks which option actually addresses the real limiting factor in a specific situation, rather than which option follows a general rule correctly. A genuinely serious bottleneck, like a legal or quality risk, deserves more weight than a general preference for flow, since ignoring the real constraint causes far more damage than temporarily deviating from a standard rule.

How does the article resolve the tension between quality and the Lean principle against unnecessary spending?

By asking what the organization’s actual product or core value proposition is. If quality is genuinely central to what a business delivers, investing real effort into improving it is not unnecessary spending, it is direct investment in the actual product itself. The article treats this as a case where two principles only appear to conflict, since protecting quality in that specific business actually serves the deeper goal both principles are meant to support.

Can these three governing principles ever conflict with each other, and if so, how should that be resolved?

The article does not fully address this scenario, and Jason himself acknowledges the framework may still be developing. In practice, working through all three questions honestly, addressing the real bottleneck, respecting the people involved, and protecting genuine quality, tends to surface which concern is actually most urgent in a specific situation, even when more than one of the three principles applies at once.
