The queue you can’t walk past

Every Monday somebody asks engineering where the job is. Engineering says it is close. Both people are telling the truth, and neither of them has a number.

This is not a discipline problem. Production inventory is visible. You can walk the floor and see the parts stacked against the wall, and nobody has to be told if the shop is behind. Office inventory takes up no space. A drawing waiting for an approval, an RFI sitting in somebody’s inbox, a job that is ninety percent detailed and has been for two weeks: all of it occupies exactly zero square feet. You cannot walk past it, so you manage it by asking, and the answer you get back is always some version of busy.
Busy is not a measurement. It is the same answer whether engineering is two days behind or five weeks behind, and by the time the difference shows up on the floor, the release date has already moved.

What INNERGY already tracks 

Engineering time is measurable, and most shops never measure it. In INNERGY, drafting is a work order phase, the same as Production and Installation, so every drafting work order carries a start date, a critical date, a duration and a progress figure.

Date Management is where that stops being a per-job question. It is a single grid of every work order milestone across every project, and it separates four things most shops keep in one column: the Target Date the system calculates, an Override Date a human typed in on purpose, the Actual Date the milestone was really hit, and the Prevailing Date, whichever of those currently governs. Two columns beside them, Days In Step and Days Overdue, do the work of the Monday meeting without anyone having to answer for themselves.

Sorting that grid by Days In Step is the uncomfortable part. The jobs that surface are rarely the ones anybody was worried about. The loud job has been loud for a reason and somebody is on it. The job sitting in the same step for nineteen days is quiet, which is exactly why nothing has happened to it.

One number for the month

Individual milestones tell you where a job is. They do not tell you whether the month is going to make it. That is the Released % metric: released hours divided by total hours, measured against a release step you configure. It answers one question, which is how much of the work in front of you is clean and gone to the floor, versus still being drawn.

The Bottlenecks dashboard puts that in context. Its Workflow and PM in Workflow tabs cross-tabulate hours, cost and margin against time ranges, so you can see whether the engineering queue is a spike this month or the shape of your operation. The Throughput and Slippage widgets sit alongside it, and Slippage drills down to which project managers contributed to the move.

There are honest limits. The measurement is only as good as the release step you set, and if that step does not match what your shop actually treats as released, Released % will be precise and wrong. There is also the question of what counts. Across INNERGY platform data, a cross-tenant rollup built in August 2026, 54.2% of hours attributed to engineering are being worked and 45.8% are waiting, and the largest single waiting bucket is work out for approval. Whether that time should count against engineering at all is a judgment call worth roughly four points either way. Your leadership team makes that call, not the software.

Why we are going to Bonita Springs 

This is a hard conversation to have in a group webinar but an easy one to have across a table, which is the real reason we go to the AWI Annual Convention.

INNERGY will be at the 2026 convention, October 21 to 23, at the Hyatt Coconut Point in Bonita Springs, Florida. Jillian Klinar, Garin Trimble and I are making the trip. Find us at the Product Fair: two six-foot tables side by side, two screens running, no theater presentation on a loop.

Fifteen minutes is enough to see what the measurement looks like on a real operation: how long a job sits between award and released shop drawings, how much of a month is actually released, and what the grid surfaces when you sort it by the jobs nobody was worried about.

What we will not do at that table is tell you the software fixes a throughput problem. It makes the constraint visible, and visible is where a team can finally act. The deciding is still yours, and any vendor promising otherwise is selling you the easy version of a hard year.

Register for the event here and come see us in Bonita Springs. We will be the ones with two screens and too much coffee.

Ask a millwork owner where the company loses money and most will point at constraints they see on the floor. The machine that went down. The crew that ran long on install. The panel that came back wrong three days before delivery.

 

Then look at the numbers. AWI Cost of Doing Business Survey data puts the engineering productivity multiplier at roughly $15.35 of downstream shop labor and materials output for every $1 of drafting and engineering corporate cost. Engineering is the highest-return dollar in the building, which makes a backlog in engineering the most expensive delay you have.

 

Nine out of ten shops named the same constraint

 

In August 2026 we surveyed 124 woodworking shops across the United States, Canada, and Australia and New Zealand about their current CAD/CAM tools. 85% named the time it takes to detail or engineer a job as a pain point. It was the number one answer in every region, and nothing else came close.

 

The pressure is building from both sides. With increased renovation and retrofit rather than new construction, and existing buildings do not cooperate: nothing is square, dimensions have to be field-verified, and phasing around an occupied space means more one-off pieces and fewer repeatable runs. Same contract value, more drawings. Meanwhile a shortage of skilled engineers pulls design windows in. More drawings, less time, in the exact place where speed decides profitability.

 

What the margin gap is actually made of

 

AWI Cost of Doing Business Survey data shows an 11-point operating margin gap between top-quartile firms and the median. Same machines, same lumber, same labor market. For a $10 million shop, that is roughly $1.1 million more EBIT every year.

 

Here is the part that surprises people: top-quartile firms spend less on engineering payroll than bottom-quartile firms and still win. The advantage is not more engineers. It is the ability to release clean work early and know where every job stands. When we polled owners at an INNERGY Summit on what that would be worth, complete shop drawings four weeks early with all materials staged, 64% said their profit would more than double.

 

“Profitability is made prior to the sawdust, in estimating, engineering, and the flow of information long before a single part is cut.”

Marc Sanderson, CEO, INNERGY

 

The instinct is to hire. The constraint is usually the waiting.

 

When engineering runs behind, the default move is another drafter. Sometimes that is right. But capacity added to a serial process is still a serial process, and in a file-based desktop tool the hours go somewhere other than engineering:

• One person per job. A second drafter means a second file and a merge at the end. 

• Crashes on custom work, which is the work that pays best. 

• Performance that degrades as job size grows, on the projects the schedule can least absorb. 

• A recut loop that routes through whoever has the file open. 

None of that is engineering. It is waiting, redoing, and hand-carrying. You cannot hire your way out of a backlog whose real cause is that only one person can be in the room.

 

What we built, and why

 

INNERGY Engineering launched on August 19, 2026: cloud-native CAD/CAM built inside INNERGY ERP, developed and hardened alongside Early Adopter shops. It aims at one outcome above all others. Get engineering done faster, because faster engineering is more throughput, and throughput is margin.

 

Several people can design and engineer in the same project at the same time, with no file locking and no waiting for a colleague to close a file. Work saves continuously, so a crash no longer costs a morning. It runs on the hardware your team already owns, and updates arrive automatically instead of as manual installs. Because engineering lives inside the platform, drawings, bills of materials, and CNC output flow through to production and purchasing instead of being re-keyed.

 

It makes its in-person debut at IWF Atlanta 2026, August 25 to 28 at the Georgia World Congress Center.

 

Three questions before you buy anything

 

You do not need new software to find out whether engineering is your constraint. You need three numbers.

 

• How many days pass between award and released shop drawings, and how much of that is work versus backlog?
• How many people can be inside your largest active job right now, at the same time?
• How many times last week did an engineer stop engineering to unblock someone else?

 

If the answer to the second is “one” and the answer to the third is a number you do not like, capacity is not your problem. Access is. That is fixable, and worth fixing upstream while the margin is still there to protect.

Everyone’s busy, the shop is moving, the PMs are buried, and somehow at the end of the month the profit doesn’t match the effort.

If you own a millwork shop, you’ve probably said some version of that out loud in the last 30 days. It feels like six different problems, but it’s one: a bottleneck you can’t see. The fix starts with a single question. Where is your work stuck?

 

Your shop only moves as fast as its slowest step

 

Eli Goldratt laid this out in his 1984 book The Goal, and it’s the foundation INNERGY was built on. Every operation has one step that sets the pace for everything else, which means speeding up any other step doesn’t make you faster. It just piles up more work in front of the slow one.

 

That has an uncomfortable implication for where you spend your attention. Most owners put 80 percent of it on the shop floor and 20 percent in the office, and in most shops that allocation is exactly backwards.

 

Here’s why. Goldratt’s way to find the bottleneck is to look for where work piles up. The pile is the diagnosis. On the floor that works great, because carts stacked in front of the finishing line are hard to miss. But in custom millwork, your most expensive pile usually isn’t made of parts. It’s made of information: the drawing sitting in the drafter’s queue, the submittal waiting on the architect, the revisions stacking up after a field change while a PM asks the same person for the same status three times in a week.

 

None of that is visible. A drawing that’s been sitting in a queue for two weeks looks exactly like one that’s been there for two hours, but that two-week queue is hurting your throughput just like a broken machine would. You can’t walk past it and see it.

 

That’s the problem INNERGY’s bottleneck report solves. It shows you where your dollars are sitting at every step of your workflow, so the invisible pile becomes as obvious as the carts on the floor. On a recent webinar, two shop owners told us what that visibility changed for them.

 

RCS Millwork: blaming the floor for an office problem

 

Joe Keller at RCS Millwork, a 100-person architectural woodworking shop, was sure the bottleneck was production. Work orders were going out the door already overdue, and when the floor missed deadlines, the floor took the heat. Sound familiar?

 

But as Joe put it, his shop never had a chance to win, because the work was late before it ever hit the floor. The real bottleneck was in the office: submittals sitting in customer review, often sent late without enough review time built in.

 

The cost of running blind might also sound familiar. RCS’s general manager, one of the most highly paid people in the company, tracked every job on a spreadsheet so large it couldn’t be shared. He spent roughly 80 hours a week on data entry just to keep it current, and it still couldn’t tell anyone where work was actually stuck.

 

Joe’s advice now is simple. On the floor, walk out and look for the carts. In the office, look at your bottleneck report. RCS uses it to see where dollars and hours are sitting by department and by project manager, which lets them spot a heavy month coming and pull work forward to level the load.

 

The payoff: after putting bottleneck management into practice, RCS moved from lower-quartile AWI profitability to upper quartile and held it there for several years. They weren’t doing more work. They were doing the same work far more profitably.

 

Busby Cabinets: 90 days instead of 18 months

 

John Miller at Busby Cabinets, a 75-person high-end residential shop, will tell you straight: if you own a company, you have a bottleneck. The only question is whether you know where it is.

 

His has moved over the years, from installation to engineering to finishing. Each time, his team worked the same playbook from Theory of Constraints: find the bottleneck, get everything you can out of it before spending a dime, and only then think about new people or machines.

 

Breaking the engineering bottleneck was supposed to take 18 months to two years. It took 90 days.

 

Finishing held the bigger surprise. Once the team had real data, it showed 60 to 65 percent of finishing capacity was being burned on rework, redoing parts that had already been through the department once. When they dug into the cause, much of it traced back to voids in their 5-ply core material that had crews filling and resanding flat panels three or four times.

 

The fix sounds wrong on paper: buy more expensive plywood. Busby switched to 11-ply Baltic birch at two to three times the material cost, and it was still an easy call, because it cut the rework in half and freed up capacity they didn’t know they had. In 90 days, finishing capacity grew by about 50 percent without a new hire or a new machine. That’s the part worth sitting with. The answer to their capacity problem wasn’t capacity at all.

 

Today Busby’s bottleneck is the market. They need more work to fill the capacity they’ve uncovered.

 

Asked which report he’d hand his past self on day one, John didn’t hesitate: the bottleneck report. Where’s my work stuck? Why is it stuck? What will it take to get it unstuck? It also gave his whole team a common language, so the conversation moved from “we’re missing deadlines and we don’t know why” to a focused fix.

 

 

Three moves for Monday morning

 

You don’t need to measure capacity at every step, and you don’t need a consultant. Start here:

 

1. Map your workflow steps, office included. Estimating and drafting count just as much as cutting and finishing.
2. Look for the pile. On the floor, it’s carts. In the office, ask your PMs and drafters where work sits waiting. That dead work-in-process is your answer.
3. Attack the bottleneck first. Before you spend money, ask what process or policy change would free up capacity at that one step. Both Joe and John found their biggest gains there.

 

And if your pile is hiding in the office, the bottleneck report makes it visible: every job, every step, every dollar sitting still. See it in action.

In custom millwork and cabinetry, profitability rarely comes down to raw speed or the size of your shop floor. What matters more is flow. How smoothly does work move from one stage to the next? Production managers and supervisors already know this. The real cost often hides in the invisible delays, not just in the pile-ups you can see.

 

That is why the right woodworking software can make such a difference. By revealing where projects are slowing down, it helps you eliminate the bottlenecks that quietly erode margins.

 

What Is a Bottleneck in Woodworking Operations?

 

A bottleneck in woodworking operations is any point where projects stack up faster than they can move forward. Picture it as a traffic jam.

 

Here’s the tricky part. The logjam might show up on the shop floor, but the real problem often starts earlier. Engineering backlogs. Material approvals stuck in limbo. Submittals waiting on feedback. For shops like Mission Bell Manufacturing in California, managing these hidden delays has proven just as important as optimizing their actual production line.

 

Most custom shops struggle with visibility. If you’re juggling spreadsheets and gut instincts to decide what comes next, you’re essentially managing blindfolded. And because custom work changes from job to job, your woodworking bottleneck today may look completely different next month.

 

Traditional fixes often backfire. Shops add staff or equipment where the issue seems obvious, but without real data, they may end up solving the wrong problem.

 

The reality is that every step in woodworking production is interconnected. A delay anywhere ripples downstream, starving work centers and creating that all-too-familiar firefighting culture.

 

How INNERGY’s Bottleneck Report Works

 

INNERGY’s Bottleneck Report is based on a simple truth from the Theory of Constraints: where inventory piles up, there’s a problem.

 

Instead of looking at departments in isolation, the report brings your entire workflow into a single view. From the first sales opportunity to installation, you can see how jobs move—or don’t move—through the system.

 

It’s also visual. Rather than combing through spreadsheets, you get a clear graphic that shows where work flows smoothly and where it doesn’t. When a stage starts backing up, the system highlights it with a “wedge,” making the bottleneck impossible to miss.

 

Customization is built in. You can define workflow steps that reflect your shop’s reality, like “Awaiting Field Dimensions,” “Pending Client Approval,” or “Ready for CNC.” Each stage has clear ownership, so when something hits the urgent wedge, your team knows exactly where to act.

 

The forward-looking capacity view is another standout. Instead of discovering a bottleneck after it happens, you see workload forecasts weeks in advance. This lets you reassign people, approve overtime, or line up outsourcing before the crunch hits.

 

For machinists and supervisors, that means fewer boom-and-bust cycles. Work arrives steadily, and preparation replaces last-minute scrambling.

 

 

Real Examples of Bottleneck Resolution

 

What does this look like in practice?

 

Take a common scenario: the shop floor sits idle while engineering is swamped with revisions. It’s not a machine problem at all—it’s an engineering bottleneck. The Bottleneck Report makes that clear, allowing leaders to redirect resources before valuable capacity is wasted.

 

Mission Bell Manufacturing experienced this firsthand. With complex projects spanning estimating, engineering, production, and installation, they often felt like they were chasing fires. Once they adopted system-wide visibility, they could finally anticipate issues instead of constantly reacting.

 

Another discovery many shops make involves materials. Jobs may appear “ready for production,” but if approvals or client selections are missing, they can’t move. Without insight into these pre-production stages, it’s easy to assume more shop capacity is needed when the real constraint sits with project management.

 

Finishing departments often tell a similar story. When too many jobs are released at once, artificial traffic jams form. By pacing release rates instead of flooding the floor, shops see dramatic throughput improvements without adding staff or machines.

 

The bigger picture is this: bottlenecks shift. They move around from month to month. Advanced tools help you keep up, so you’re always solving today’s problem instead of yesterday’s.

 

 

Steps to Implement Continuous Improvement

 

So how do you put this into practice?

 

1. Start with visibility. Map every step of your workflow, from estimating and engineering to shop floor operations. The goal is a complete picture of how work moves.

 

2. Assign ownership. Each step needs someone responsible. When a bottleneck appears, that person must have the authority to act.

 

3. Review regularly. Weekly meetings should begin with the Bottleneck Report. Instead of debating who is busiest, you discuss where the flow is breaking down and what to do about it.

 

4. Use the Five Focusing Steps. Identify the bottleneck, keep it fully utilized, align everything else to support it, add capacity if needed, then restart the cycle once the bottleneck shifts.

 

5. Tie in woodworking project estimations. Historical data from the report helps sales set realistic timelines. This prevents overpromising and reduces the chaos that creates bottlenecks.

 

6. Train your team. Tools only work if people know how to use them. Make sure staff understand how to read and act on the report.

 

 

Metrics That Matter

 

Along with the report’s visuals, a few key metrics help you stay on top of shop flow:

 

1. 1. • Work-in-progress by step. Track not just job counts but also hours and dollar value.
      • Cycle times. When projects start spending more time in a stage than usual, that’s a red flag.
      • Throughput rate. Focus on how much work gets delivered over time, not just efficiency in one department.
      • On-time delivery. Drops here almost always trace back to hidden bottlenecks.
      • Constraint utilization. The bottleneck sets your output. It should never sit idle.

 

Conclusion

 

Becoming more efficient is not about pushing harder or buying more machines. It’s about seeing the system clearly and managing flow with intention.

 

With a modern ERP, shops can shift from guesswork to data, from firefighting to proactive planning. Spotting bottlenecks before they hit, balancing capacity intelligently, and focusing on the right constraint each day turns chaos into predictability.

 

The woodworking industry is only getting more complex. Customers expect faster timelines and flawless quality. Shops that adopt tools like the Bottleneck Report and ERP systems will have a competitive edge. Those clinging to spreadsheets and gut feel risk falling behind.

 

At the end of the day, your operation isn’t limited by your machines or even your talent. It’s limited by the slowest point in your workflow. Find it. Manage it. And watch the rest of your shop accelerate.
