Keeping It Simple
The fastest, simplest ways to grow your business - no jargon, no fluff. Practical strategies that actually work for SME owners in the USA, New Zealand, and worldwide.
Most owners respond to a bottleneck by fixing something else. The warehouse is backed up, so they buy new software for sales. The team is stretched, so they hire another generalist instead of fixing the one role that's actually jamming up the flow of work. Eli Goldratt's Theory of Constraints, developed at Toyota and popularised through his business novel "The Goal," makes a single, simple claim: every system has exactly one constraint limiting its output at any given time, and improving anything that isn't the constraint is close to a waste of effort. A review of documented Theory of Constraints case studies across manufacturing and service businesses found a mean lead-time reduction of 69 percent and a mean revenue or throughput increase of 68 percent once the real constraint was identified and managed. Kevin D'Ambros-Smith has run this diagnostic with SME clients across industries from eCommerce to engineering, and it's almost always the first real fix a business needs.
Fixing Everything Except the Thing That's Broken
The named enemy is diffuse effort. A business under pressure tends to improve whatever is easiest to improve, a new tool, a new hire, a new process, rather than whatever is actually capping output. Goldratt's insight is that none of that secondary work changes the business's total throughput if it isn't aimed at the constraint. A faster sales team selling into a production line that's already maxed out doesn't grow revenue. It grows a backlog.
The Theory of Constraints, in Plain English
Goldratt's five focusing steps, adapted for an SME rather than a factory floor:
- 1. Find It — map the workflow and identify the single step where work piles up waiting, not the step that looks busiest.
- 2. Exploit It — get everything possible out of that step before spending a dollar on it. Remove interruptions, protect its time, clear its queue first.
- 3. Subordinate Everything Else — every other part of the business adjusts its pace to match the constraint, instead of each department optimising for itself.
- 4. Elevate It — only once steps one to three are exhausted do you invest, hire or buy equipment to expand that one step's capacity.
- 5. Repeat — once that constraint is fixed, a new one appears somewhere else. Go back to step one.
"Kevin has simplified a lot of the processes that have been floating in my head. It has made things easier to navigate as we begin to launch a new service offering to the market. I feel confident and able to do this, thanks to Kevin."

Why Owners Know This and Still Don't Do It
Finding the real constraint is uncomfortable, because it's often not where the owner wants it to be. It might be the owner themselves, approving every invoice personally. It might be a star employee who has become a single point of failure. Owners understandably gravitate toward fixes that don't require that kind of honest look inward. An outside diagnostic, run by someone with no stake in protecting any one department or person, tends to find the real constraint in a single session rather than months of well-intentioned but scattered improvement.
Quick Wins
- Map your core workflow on one page and mark where work visibly queues up waiting.
- Protect that one step's time today, cancel one meeting or interruption that eats into it.
- Before approving any new hire or tool, ask whether it actually expands the constraint, or just makes something else faster.
Key Takeaways
- Every system has exactly one constraint limiting its total output at any given time.
- Documented Theory of Constraints case studies show a mean 69 percent lead-time reduction once the real constraint is managed.
- Fixing anything that isn't the constraint rarely changes total output, it just moves the backlog.
- Exploit and subordinate before you spend money elevating capacity.
Before your next hire or software subscription, find out whether it's actually solving your constraint, or just feeling productive.
