How Should A General Contractor Choose A Lean Construction Training Or Consulting Partner?

How Should a General Contractor Choose a Lean Construction Training or Consulting Partner?

Here’s the deal. I am a Lean trainer and a Lean consultant myself, which means you should treat everything I say here with a healthy amount of skepticism and go get other opinions too. With that disclosure out of the way, here is what I genuinely believe, based on running this business and watching plenty of implementations succeed and fail.

Consultants Are Genuinely Useful, and That Is Not a Sales Pitch

Coaches, trainers, and consultants are a real, legitimate part of taking a business to the next level. I have never once seen a company make that leap without them. We have used them constantly at Elevate ourselves, even in our first years, when I cashed in my own retirement just to get the business started. We have paid for executive coaching, for business operating system consulting, for LinkedIn coaching, and currently for help making sure our content is actually findable through AI powered search. We have used SEO specialists and business consultants along the way too. Hiring outside expertise is simply part of how a business gets better.

Even Paul Akers, whose book 2 Second Lean opens by saying you do not technically need a Lean consultant, describes in that same book how his own next step involved hiring one to come into his shop and paying for a trip to Japan to see Lean practices firsthand. People say you do not need consultants. In practice, the people saying that tend to have used one anyway.

A Story About What Happens When a Company Only Wants to Dabble

If you genuinely just want to say your company does Lean, without going any deeper than that, you can hire almost anyone and get away with it. I saw this play out directly with a local contractor. A consultant had them running what he called a three week pull, which is not actually a pull plan at all. A real pull plan is organized by phase, not by a rolling time window. What that company actually got was a look ahead plan moved from Excel onto sticky notes, dressed up in Lean language so it could be mentioned in proposals.

That was fine with the people involved, because going deeper was never really the goal. Some of the operations staff at that company genuinely did not want to take it further, so a shallow implementation suited everyone just fine.

What Happened When That Same Company Went Deeper

That same company later hired us to actually implement the full system on an eighty five million dollar project that ultimately grew to one hundred twenty million dollars. We worked with them on real pull planning and a genuine Lean implementation, and the results were dramatic. The project ran ahead of schedule and under budget. The onsite team was genuinely happy. Signage and visual systems were done right. The owner was impressed, and so were the trades. We still have showcase footage from that project.

Here is the part worth learning from directly. Our growing influence made the field operations manager and the original consultant genuinely nervous, and they moved quickly to have us removed from the project. That is the real crux of the issue. Going all the way with a Lean implementation requires managing internal dissension, securing genuine buy-in from the people who influence the organization, and being fully prepared to follow through. If you actually want to kill a Lean effort, here is exactly how to do it. Keep leadership from being genuinely all in. Focus on profits and money above everything else. Let a scheduling or legal director who fears losing significance quietly resist the change. Or simply allow dissenters to undermine the effort because they personally dislike change.

Watch for these signs internal politics are quietly working against a real Lean implementation:

• Leadership publicly supportive of the effort but not genuinely engaged in driving it
• A scheduling, legal, or administrative role that seems threatened by the growing influence of the new system
• Vocal resistance to change tolerated without any real pushback from leadership

Red Flags to Watch for in a Potential Consultant

There are specific warning signs worth checking before signing with any Lean consultant, and the first one is basic diagnostic work. A genuine consultant needs to ask where your organization actually wants to go, assess your organization directly, and visit you in person before proposing anything. A consultant who skips straight to selling you a predetermined package, without ever diagnosing your actual situation, is at minimum a real orange flag, the same way a doctor cannot responsibly diagnose anything without running actual tests.

The second red flag is a consultant who suggests going slow or implementing just one small piece at a time. That advice sounds cautious and reasonable, and it is actually one of the least Lean things you can do. It is called sub-optimization, improving one isolated piece while the entire system around it stays unimplemented, which rarely produces meaningful results.

The third red flag is a consultant who only genuinely knows one tool. Somebody who only knows Last Planner will only implement Last Planner. Somebody who only knows theory of constraints will only apply that. Somebody fixated purely on advanced work packaging or purely on Takt will do exactly that and nothing more. A consultant needs to understand the entire Lean spectrum, theory of constraints, line of balance, location based scheduling, Takt, Last Planner, Kanban, general Lean manufacturing, fabrication facility principles, and advanced work packaging, and be able to explain clearly how all of those pieces connect to each other. If they cannot articulate that connection, that is a genuine red flag.

Why the Underlying Framework Matters as Much as the Tools

A genuine Lean partner needs to understand a specific pattern. Construction has to be planned on a real rhythm together with the trades, which means genuine fluency in the pre-construction planning system, the Takt production system, and the Last Planner System together, not any one of them in isolation.

There is a useful framework from the book Switch worth applying here. People need to know what they are actually supposed to be doing, they need to genuinely want to do it, and they need circumstances that actually let them succeed at it. Translated into a scaling pattern, that means a real business system, a real operating system, real training so everyone gets brought up to speed together, and monthly field walks to reinforce the implementation in practice. Skip any one of those four and a Lean effort will not scale across an organization, no matter how good the initial pilot project looked.

The Single Biggest Red Flag of All

If a consultant is genuinely pro-CPM, that is worth treating as disqualifying. Anybody who tolerates or defends CPM at this point is either unaware of the consequences it produces, does not genuinely understand Lean thinking, or understands the harm it causes and continues to defend it anyway. None of those three options is a good foundation for a genuine Lean partnership.

How to Actually Evaluate a Potential Partner

None of this needs to be figured out entirely alone. If your project needs superintendent coaching, project support, or leadership development, Elevate Construction can help evaluate whether a specific consultant genuinely understands the entire Lean spectrum, or whether they are likely to leave you with a shallow, sub-optimized implementation dressed up in the right vocabulary.

So here is the challenge. Before signing with any Lean consultant, ask them directly to walk through how theory of constraints, Takt, Last Planner, Kanban, and advanced work packaging connect to each other on a real project. If the answer is vague, or if they immediately steer the conversation back toward the one tool they know best, that conversation just told you everything you need to know.

Jason Schroeder said it plainly: “Sub-optimization is the most unlean thing you can do.” Choose a partner who understands the whole system, not just the one piece they happen to sell.

On we go.

FAQ

Why is suggesting a slow, one piece at a time rollout actually a red flag rather than sound advice?
Because it produces sub-optimization, meaning improvement in one isolated area while the rest of the system remains untouched, which rarely produces the kind of results a genuine Lean implementation is capable of. A consultant who genuinely understands the full system will typically recommend implementing the business system, operating system, training, and field support together, since each piece reinforces the others.

How can a general contractor tell whether internal politics are likely to undermine a Lean implementation before it even starts?
Watch for leadership that is publicly supportive but not genuinely engaged in driving the change personally, and watch for roles like scheduling or legal that might feel threatened by a new system gaining real influence. Securing genuine buy-in from those influencers before a deep implementation begins is far easier than trying to repair sabotage after resistance has already taken hold.

Why does the article treat a pro-CPM consultant as an automatic disqualifier?
Because CPM’s structural flaws, including trade stacking, trade burdening, and the absence of real buffers, are well documented at this point. A consultant who still defends or tolerates that method is either unaware of those consequences, does not genuinely understand Lean principles, or understands the harm and continues anyway, none of which makes for a trustworthy foundation for a genuine Lean partnership.
