Takt Planning Fable
The Fable - Flow Builders
The Railroad - An Analogy for the Takt Production System
The Hierarchy
The Program is the railroad — the whole enterprise. Tracks across a continent. Locomotives in service. Stations staffed. Crews trained. Schedules published. Investors paid. The Program is not any single train or any single route. It is the entire concern, run as one institution, accountable for every wheel that turns.
A Project is a rail network within that railroad — a regional system. The Pacific Northwest network. The Midwest network. A defined geography with its own routes, its own stations, its own freight and passengers, but operated under the same standards as every other network in the company. A rail network is large enough to fail on its own, and large enough to be measured on its own. So is a project.
Milestones are the end points on the line — the stations the train must arrive at, and arrive at on time. Not signposts. Not ribbons. Stations, where the schedule holds its meaning. If the train does not get there at the published hour, the system has failed. Milestones are not aspirations. They are the points the railroad has promised the public it will hit.
A Phase is a rail line within that network — a specific corridor between specific points. Seattle to Portland. Chicago to St. Louis. A line has a beginning and an end. It has a defined purpose. It is a route the train will run, in the order it will run it. A phase, like a line, is named by where it starts and where it ends.

It is a route the train will run, in the order it will run it. A phase, like a line, is named by where it starts and where it ends.
The Trains and Their Tempo
Trains, wagons, and trade flow are trains — full stop. A train is a sequence of cars hauled by a locomotive in a fixed order, on a fixed track, at a fixed speed. The order matters. The locomotive cannot be at the back. The dining car cannot be ahead of the engine. Each car has its job, each car follows the car in front of it, and each car carries its weight without becoming the whole train. A trade flow on a Takt project is the same thing. A line of crews moving in a fixed sequence, each one doing its part, each one feeding the next, none of them mistaking themselves for the engine.
Zone size is the speed of the train. Smaller zones, faster trains. Larger zones, slower trains. The size of the zone, like the speed of the train, is the choice that governs everything downstream — how many cars the line can carry, how often they arrive, how quickly the system breathes. It is not an afterthought. It is the first decision.
Takt time is the rhythm of the train. The interval between cars passing a given point. The drumbeat of the line. A train running on Takt does not run faster when the engineer feels strong, or slower when the engineer feels tired. It runs at the rhythm the schedule has promised — because behind that train is another train, and behind that one another, and the rhythm is what keeps them from colliding.
The Macro is the baseline time the railroad has promised the public. Seattle to Portland in three and a half hours. The number printed in the timetable. The number the dispatcher answers to. The number a customer plans their day around. The Macro is the public promise, and once it is published, it cannot be moved without consequence.
The Norm is the optimized run the engineer was actually able to achieve — the schedule the railroad runs the train against in practice, once it has learned the line. Three hours and twenty minutes, on a clear day, with experienced crews and well-maintained track. The Macro is the promise. The Norm is the performance underneath the promise. The two are different documents, run by different people, used for different conversations. Confusing them is one of the oldest mistakes in railroading.
The Path and the Connections
Buffers are the extra time built into the timetable for the things you cannot predict. A signal failure. A herd of cattle on the line. A passenger who slipped on the platform. The published time between Seattle and Portland is not the fastest the train could run on a perfect day. It is the fastest the train can reliably run on an imperfect one. Buffers are not waste. Buffers are what allows the system to deliver on the Macro when reality refuses to cooperate. A railroad with no buffers is a railroad that misses its arrivals.
The Path of Critical Flow is the route the train must take to reach its destination on time. Not every track the train could theoretically run on. The specific sequence of segments, switches, and signals that governs whether the train arrives. The dispatcher’s eye is on this path. The maintenance schedule is built around it. When something goes wrong on the path of critical flow, every other decision in the network bends to protect it, because if that path slips, the timetable slips, and the railroad has broken its promise.
Interconnections are the points where one train enables another. The mainline arrives at the junction; the branch line cannot leave until the mainline has passed; a third train is held at the platform until the branch line clears. Trains do not run independently. They run in relationship. Every interconnection is a moment where the discipline of the schedule is tested, and where the absence of discipline shows up first as a delay and then, if it continues, as a wreck.
Independent activities are the work that runs alongside the line without crossing it. Maintenance trains on side tracks. Yard switching. Station cleaning. Signal calibration. Ticketing windows. None of this stops the mainline; none of it is timed to it; but all of it is necessary, and all of it must be planned, staffed, and accountable. A railroad that ignores the work on the side tracks finds, eventually, that the side tracks have stopped working — and then the mainline cannot run either.
The Supply Depot
A train does not create what it carries. It moves what has been staged for it to move.
Behind every working railroad is a network of depots, warehouses, team tracks, and freight yards where the cargo lives before the train arrives. Coal at the colliery siding. Grain at the elevator. Lumber on the team track. Manufactured goods in the warehouse at the edge of the yard. The cargo is not on the train when the train rolls out of the originating station. It has been gathered, sorted, and switched onto the train in the order the train will need it — bottom of the consist first, top of the consist last, the car for Cleveland coupled ahead of the car for Buffalo because Cleveland is the earlier stop.
That is the work of the supply depot. And the relationship between the depot and the mainline is the relationship that makes or breaks the timetable.
If the freight is not at the depot when the switching crew comes for it, the train leaves short. If the freight is at the depot but in the wrong order, the train rolls into Cleveland with the Buffalo cars on top, and an hour is lost untangling what should have been untangled in the yard. If the depot is full but the switching crew is late, the train waits at the platform with steam up and a crew on the clock, burning money on a delay that is not the train’s fault and is not the depot’s fault but is, very much, the system’s fault.
The materials on a Takt project are freight on a railroad. They live, before they are needed, in a depot — a yard, a laydown area, a fabrication shop, a vendor’s warehouse two states away. They must be staged, sequenced, and delivered to the station the trade is working in, on the day the trade is working there, in the order the trade will install them. Not before. Not after. Not in a pile in the wrong room. In the right place, at the right time, in the order the work will consume them.
The discipline this requires is the discipline of the freight yard. Someone has to know what is in the depot. Someone has to know what the train needs and when. Someone has to switch the cars onto the consist in the order that serves the route, and someone has to release them to the line on the cadence the timetable has set. None of this is glamorous. All of it is the difference between a train that runs and a train that sits at the platform with nothing to carry and nothing to deliver.
The trades are the trains. The materials are the freight. The depot is everything that lives between the vendor and the work face — the laydown yard, the staging area, the just-in-time delivery, the kitting cart that arrives at the zone the morning the crew enters it. A railroad that runs its trains beautifully and lets its depots run themselves does not run for long. The depot is not a separate concern. The depot is half of the railroad.
A train without freight is a locomotive making noise.
A trade without materials is the same thing.
Risk and the Honesty of the System
Fresh-eyes review is the act of walking the line before the train runs. A second crew, with no stake in the schedule, walking the rails, testing the switches, listening to the signal bells, asking why a particular curve is rated for the speed it is rated for. The crew that built the line cannot see the line clearly anymore. The fresh-eyes crew can. They are not hired to admire the work. They are hired to find what the original crew has stopped being able to find. The best railroads insist on this before any new line carries a passenger.
Constraints are the things that limit how fast the train can run. The grade on a hill. The radius of a curve. The weight rating of a bridge. The horsepower of the locomotive. The condition of the rail. Constraints are properties of the system; you do not eliminate them by working harder. You eliminate them by changing the system — laying heavier rail, regrading the hill, replacing the bridge, ordering a stronger locomotive. Constraints are honest about what the railroad can and cannot do, and the railroads that listen to them outlast the ones that do not.
Roadblocks are the things in the way of the train. A tree across the track. A landslide in the cut. A boxcar parked on the wrong siding. A roadblock is not a property of the system. It is an event in the system. It is removed, not redesigned. But until it is removed, the train cannot move, and the cost of the roadblock is the time the train was scheduled to be running and was not.
The first job of every crew on every railroad is to know the difference between the two. The constraint is the bridge; the roadblock is the tree on the bridge. You cut the tree. You replace the bridge. Conflating the two is how lines die.
Steering the System
The meeting system is the check-in cadence the engineers and dispatchers run to keep the railroad operating. Morning briefings. Hourly position reports. Tower-to-tower handoffs. The conductor’s check at every station stop. None of these meetings are about the railroad in the abstract. Each one has a job — confirm position, confirm next move, surface any condition that has changed since the last check-in. The meetings of a railroad are not where the railroad gets debated. They are where the railroad gets steered.
Zone control is inspection as the train moves. The trackwalker who walks ahead of the train to check the rail. The signalman in the tower who watches the train pass. The dispatcher who sees the train’s position update on the board. The conductor who walks the cars. Zone control is not a single inspection at the end. It is a continuous one, distributed along the line, performed by people whose job is to catch the small thing now so it does not become the large thing later. A railroad without zone control is a railroad that finds out about its problems at the next derailment.
Delay management is the dispatcher’s craft. When a train is late, the dispatcher does not ask the engineer to drive faster. He cannot. The track has a speed limit; the bridge has a weight limit; the curve has a radius. What the dispatcher does instead is reroute, re-sequence, hold a connecting train at the platform, release a passing siding earlier, send a relief locomotive up the line. The art of delay management is doing whatever can be done within the limits of the system to protect the next promise. Pushing the train is not part of that art. The track will not let you. The system will not let you. And if you try, the railroad will pay for it twice — first in the failure of the push, and second in the wreck the push almost caused.
The Timetable
The first American railroads ran on local time. They were not failing for it — they were succeeding, in the way an industry can succeed at the small scale and run out of room at the large one. A single line between two cities could be coordinated by experienced crews and good intentions. A continent could not. The railroads did not wait for a wreck on every line to convince them. They looked at the system they had, recognized what it could and could not carry, and built a better one. They drew the lines. They picked the day. They reset the clocks at noon. And then they ran their trains against a timetable the whole country could read.
That is the move. Not the collapse before the change — the recognition before the collapse.
A construction project sits in the same place.
If every trade is keeping its own time, the project is running on local clocks. There will be activity. There will be effort. There will, on the right days, even be progress. People will succeed inside it the way the early railroads succeeded — by knowing the line, knowing the crews, and carrying the system on their backs. But there is a size, and a complexity, and a pace at which the local-clock system runs out of room. Every builder who has lived through a project that almost came apart knows where that line is. They have stood on the wrong side of it.
The Takt Production System is the timetable. The cadence is the beat. The trades are the trains. The zones are the segments. The Macro is the promise. The Norm is the run. The buffers, the constraints, the meetings, the inspections, the delay management — all of it exists to keep the trains moving on the timetable the system has published.
You do not have to wait for the wreck.
You can draw the lines. You can pick the day. You can reset the clocks.
Build the railroad.
Keep the time.
Let the trains run.
Stasis
The Director
Olivia was the youngest director at Evergreen Construction but not because she was favored or especially lucky. Her performance was almost always spot-on, and she had a rare ability to disarm even the most volatile of situations, connect with people on a deeper level, and create a sense of calm. She loved her work and her unique high energy permeated her projects. When she was on the job or over the job, everyone felt compelled towards better performance. Being a fifth-generation builder, she firmly believed that building was in her blood. By all accounts, Olivia was born to be a builder. She knew what she was doing and she expected her team to as well. Close observers in the company realized that she was destined for higher levels of success and authority, but even competitive colleagues didn’t seem to resent it—probably because she always cared for and worked with people. She was open to her team both emotionally and intellectually. When getting things done, there were never any casualties and few deviations or missteps.
Olivia took pride in her ability to leverage her team and pull in resources as necessary. She was masterful when organizing the chaos and madness of a project and turning it into a success, but right now she found herself concurrently overseeing eight projects, and her presence was stretched too thin to be effective. While her supervisors had complete confidence in her, she was becoming uncharacteristically stressed and uncertain. How could she maintain success on so many projects at once if she wasn’t physically present? How could she train and mentor others to lead these projects in a way that would replicate her stability and create a reassuring atmosphere for the teams and owners?
The Project Team
The Start
The project had gone well from the start and things mobilized quickly. The team worked cohesively, and Olivia was once again credited for driving the success in overcoming project obstacles and roadblocks. In fact, she had been sold as the senior project manager on the project and was the main reason the company had won the proposal. However, as authority began to transition from Olivia to the onsite superintendent and project manager, things began to unravel. Undetectable at first, the drift toward instability became obvious as certain deadlines slipped, the team morale started to decline, and they began to have safety incidents. As new projects demanded her attention, Olivia was only able to stay with the team for about three months. Olivia and the Evergreen CEO were in agreement that Brad and Paul would have to step up.
The Trigger
Safety Reporting
Frustration
Despite the fact that Olivia should be focusing on the upcoming bid proposal and interview, Jeff’s call overshadowed everything else that day. It was difficult not to be angry about the situation; the team had all the skills they needed, they had the training, they had past successes. They had implemented Last Planner® and Scrum concepts. Contracts were in place and the best trades were selected. So what was the problem? Olivia had all the pieces to the puzzle laid out in front of her but she couldn’t fit them together.
The Interview
When the selection panel entered, the tension in the room was palpable. Abby, with her infectious laugh that often helped set the tone for the rest of the team, was oddly quiet. She’d seemed down this morning, but Olivia hadn’t taken the time to chat and now wished she would have. Juan still seemed flustered about his late arrival. The energy that Olivia had come to expect from this team was missing. No inroads were made with the stiff members of the selection panel. By the time introductions were made and everyone took their seats, Olivia was certain that Evergreen would not be asked to partner with Encompass Medical. The group wasn’t functioning as a team; they seemed more like uncomfortable strangers who had been thrown into a room together. Though Olivia and the team members began to find their footing, she had a sinking feeling that it was too late; they could not overcome their dismal first impression. She was pleased that Evergreen finished strong and left with their heads held high, but the parting “thank yous” from the selection panel seemed perfunctory, rather than congratulatory. They sounded more like goodbyes and condolences. The team just knew.
He smiled for the first time all morning. “Absolutely. Right now?”

The Weekly Work Planning Meeting
People Problems
The Consultant
The Phone Call
Hiring Elevate
Olivia sounded more confident than she had during their previous conversation. David was excited about the opportunity to work with Evergreen, but he felt the need for caution as well. Olivia had wanted to move fast through the initial call and consultation, which indicated big issues. David was confident in his ability to help solve problems, but he knew he could face a possible combination of stubbornness, pride, and even fear that would be an obstacle to them accepting his help.
The Surprise
The Trip
On the way up to the rafting tour’s headquarters, David and Olivia talked about her experience, the status of the projects she oversaw, and some of the background behind the problems they were facing at OneCare. Once the entire team was assembled, the guide began his safety instruction and everyone rechecked their gear and supplies. The group then rode the shuttle to the launch site. David took the opportunity to watch the team which consequently took his mind off his own trepidation about the rapids. And there was trepidation. Though he and his wife had lived in the area for over twelve years and taken their kids on many outdoor adventures, they had never been whitewater rafting. Their older kids would love it though. They had been excited for him to go. That thought gave him a boost of confidence in the experience. Maybe he would enjoy it enough to put it on the family adventure list. It was so much cooler up in the woods, which would be a nice break from the Phoenix temperatures, and it was only three hours from home.
The more David watched Olivia’s team, the more he appreciated the characteristics he was witnessing. They were confident, safe, open, and high functioning. Even the project engineers would joke with Olivia, and there did not seem to be any excessive hierarchy among them. As he observed, he began to rule out that it was an Evergreen team issue. Even Brad seemed like a remarkable leader—all too unusual in a superintendent. David had no clear idea what the root of the problem was but was pleasantly surprised that there wasn’t a lot of unhealthy contention within the group. As a consultant, his job could involve heavy pressure when pointing out specific individuals.
“I’ve never felt so much exhilaration in so much chaos. We could’ve flipped over at any minute, but I felt that adrenaline kick in and I was in the zone!”
“That’s what happens every time I go,” Olivia said. “For me, the rush comes from being near the danger. That’s why I do white water rafting; calm rivers are no fun. You don’t know when you’re about to come up against a rock; you’re always ready for anything. You knock into something and you trust the guide and then eventually, you’ll start to be able to trust your own skills.”
The Campfire
Onsite
The Problem
Olivia looked at David and said, “Now that you’ve explained it a little bit, we’d like you to present a more detailed plan for implementation of Takt. We need to see what that would look like. Is that doable?
Trains
The Meeting
“Thanks, Olivia,” David said as he positioned himself next to the projector’s screen. “The word Takt means rhythm; it indicates the beat or the rate of flow for something. Takt planning is essentially a planning system that incorporates flow, stability, and a certain amount of predictability. If you use this system for preparing work and setting milestones for the Last Planner® and Scrum teams, they will have targets they can hit and a game they can win.
Olivia made some train analogy notes:
- Land Survey = Determining Takt time and throughput
- Design of the railway system = Takt plan
- Clearing the path and making a level track = Leveling trades
- Railroad ties = Operations, or how the site is run
- Rails = Prefabrication
- Cowcatcher = Roadblock removal
- Front engine = Pre-planning team
- Engineers = A high performing team
- Takt wagons = Workers, information, and equipment
- Contents of wagons = Work product
- Caboose = Finish as you go
- Speed of the train = Takt time
- Arrival sequence of trains to the station = Throughput
- Mountains = Constraints
- Weather = Burden on the system
Plan:
- Create project Takt plan
- Discuss with OneCare
- Rally trades
- Issue zero-dollar change orders
- Implement fast
- See that everyone’s heading in the same direction
Method:
- Improve worker conditions
- Stabilize all operations
- Measure continuous improvement
Dissension:
Olivia appreciated his frankness and knew it was time to give everyone a reason to unify. “Team, I had a difficult conversation this afternoon. Jeff spoke to Brian this morning. David, Jeff is the senior VP over OneCare. We won’t be shortlisted for any future work until we’ve come up with a permanent solution to the problems we’ve been having. Evergreen’s image is suffering, our reputations are on the line, and there is no easy way out of this. I want everyone here tomorrow morning at eight, ready to make a decision, weigh in, and buy in completely. I’m meeting Brian for lunch, and I want to give him our plan.”
The Critical Choice
The Discussion:
“Alright.” David was in his element. He looked at the group, excited at the challenge they faced. “Let’s do this! The first step is to establish a plan with flow and then get everyone on the same page
Reversal
The Switch:
- Wall framing
- Electrical and plumbing wall rough-in
- Ceiling, soffit framing, and inspection
- Hang drywall
- Tape and finish drywall
- Paint
Creating the Plan:
The “Fresh Eyes” Meeting:
- Confirm procurement for separated phases - Brad, 1 week.
- Can the OFCI equipment dates be leveled according to the new plan? - Olivia, 7 days.
- Create an org chart by functional area to send out to the trades - Juan, 2 days.
- Does the schedule have weather and schedule contingency?
- Have trade partners vetted their durations in some form?
- Are there any owner activities that the contract requires be included in the construction schedule?
- Has the early or long lead procurement been identified?
- Have we included mockups?
- Does the exterior mockup trigger the release of all materials or is it an assembly mockup and not performance mockup?
- Will field measurements be required before material (counter tops, metal panels, glass, etc.) are ordered?
- Is it appropriate to guarantee openings in order to eliminate long lead times late in the project?
- Have we accounted for the procurement duration of owner provided items and can we tell them when they need to be ordered and delivered? Will the owner provide these?
- Is procurement strategically entered, has the PM reviewed and confirmed durations, and is it leveled for the designers?
- Make sure all dry-in ties are correct.
- There were reminders interspersed with more questions.
- Look at the completion of exterior to interiors and ensure there are no come-back areas.
- Look at the staging of the elevator on level 1 or basement. Do not plan on building that area right away.
- Level 1 will always be torn up during construction. Can you go top down?
- Have we coordinated the schedule with the steel erector so we represent the sequence in which the building will be erected? Will the rest of the building will sequence off this plan?
- Do we have a plan for when the permanent power will be turned on for the building?
- Will there be a need for a temporary roof?
- Does the flow incorporate specialty rooms (restrooms, IDF, MDF, mech, fire rise, SES, etc.)? Would it make more sense to break these up?
- Ensure the skin and roof are complete enough by the time drywall or insulation starts.
- Ensure exterior skin is in place in time for interior framing and drywall to connect to it. If not, are there comeback areas?
- Is there some form of climate control functioning before high-end millwork is installed? If not, is there a risk plan to manage?
- Have we accounted for time for wood products to acclimatize to the building?
- Ensure commissioning is detailed enough at the end of the schedule.
- Is the path for turning power on built in the schedule?
- Do we show the path to air on, and is it linked back to finishes?

Olivia knew Brad wanted to ensure everyone in this room knew how this system would support and maintain better safety standards and practices. The positive reactions to these concepts during the meeting were evident.
Jeff nodded, impressed. “Okay, we’ll meet three weeks from now to assess—as long as our insurance walks show excellent for the next three weeks,” Jeff said. “If not, I’ll be back sooner to discuss this.”
“Thank you Jeff and thank you team for your time and efforts here today,” Olivia said, and she closed the meeting.
- Clean bathrooms
- An air-conditioned lunch area
- A redesigned conference room area
- Every contractor working from one schedule with the zero-dollar change order
- A meeting system of planning the next day and huddling daily with the workers
- Less worker counts onsite due to more flow efficiency
- Clean areas that crews controlled as a part of their sequence
- A project team holding people accountable
- An office team with more ability to stabilize procurement with consistent datesAn office team with more ability to stabilize procurement with consistent dates
Takt is a holding system, not a push system. When people try to keep pushing they lose the genius of the system. Holding means flow. When you flow, you go fast. Much like the Navy Seal saying, “Slow is smooth, and smooth if fast,” with Lean, “Holding is smooth, and smooth is fast.” When Jeff visited the site six weeks after that OAC meeting where they began to implement their Takt plan for OneCare, he saw an entirely new jobsite.
In Spite of...
Starting with Takt
- Takt—up and to the CD phase
- Implementing “fresh eyes” meetings
- The buyout of Takt and Lean in contracts
- Setting up logistics to support Takt
Future Projects:
- Intentional Pre-construction Efforts - All projects are to follow the Evergreen First Planner System leading up and to a “fresh eyes” meeting for every project.
- Lean in Contracts - Takt, LPS® and Scrum in addition to Lean behaviors and systems are to become a part of the master subcontract agreement and be included in work authorizations.
- The Last Planner® System - The Last Planner System® is to be standardized with modifications needed to merge it with the Takt planning process.
- Prefabrication - Prefabrication will become the default for projects. Stick-built work is to be done only when authorized.
- Win Over the Workforce - Worker bathrooms, lunchrooms, barbeques, parking, smoking areas and morning huddles are to be Evergreen standard for all projects as the minimum.
- Orient People Well - Orientations will onboard workers and foremen to Takt, LPS®, Scrum, and concepts of flow. Foremen are to be trained monthly on these systems.
- Design Remarkable Interaction Spaces - Interaction spaces are to be standardized for Evergreen projects to support integration and e traincollaboration.
- Implement Zero Tolerance - A company approach to zero tolerance is to be coordinated with field ops so projects can focus on executing work in a safe manner.
- Grade Contractors - Contractor grading is to be scaled generally, with reporting that enables leadership and estimates to see how trades are performing.
Here is where we leave them behind and you become the main character of the book. The rest of our book describes the steps David taught the team for their Takt journey, and we’d like to welcome you to take the same journey. What will you do to implement Takt on your project? Whatever your next move is, we want you to know we’re cheering you on as you begin your fight against waste and variation. Every week, month, and year of learning Takt will become more and more exciting. Once you and your company begin implementing Takt planning and Takt control, you will begin to see huge gains in production which will lead to increased profits and shorter overall project durations—not to mention the stability and flow that will protect families and people on our job sites. Stay with it. On we go!
