Try This Simple Exercise
A few years ago, a colleague shared a frustrating story: her team was working tirelessly to meet a critical deadline, but progress was painfully slow.
She added more resources, but that didn’t help.
She motivated her team to work harder, but that didn’t help.
She tried every possible solution, but the delays just kept piling up.
Eventually, after many months of stress and countless heroics from the team, they found the culprit.
It was a single bottleneck—an overburdened approval process in the workflow — the most inconspicuous of steps — that caused the entire workflow to grind to a halt.
So, although her team was delivering more and faster than ever before, the approval process acted like the weakest link in the chain.
I have run into many such situations in my own experience. Many times over.
According to the Harvard Business Review, inefficiencies caused by poor workflow management cost organizations an average of 20-30% of their annual revenue.
As leaders, we often face scenarios where one weak link in the chain derails everything. This is where the Theory of Constraints (TOC) shines as a powerful framework to identify and address the bottlenecks holding your team back.
In this issue, I will discuss the ins and outs of this powerful framework, and how you can start applying it in your work. Let’s do this.
What is the Theory of Constraints?
I was first introduced to the theory of constraints in The Goal by Eliyahu M. Goldratt, a required reading for my MBA several years ago.
Unlike most ‘required reads’ in MBA and other professional programs, this book hooked me like none other. It’s written as a fable, and I finished the book in three days straight. You should definitely check it out.
Okay, back to the framework.
The Theory of Constraints was designed to improve systems by addressing their weakest points. Any workflow or process has its weakest point. For example, when you think about aircraft safety, the weakest points are the takeoff and landing, which are by far the most dangerous “phases” in the entire journey. That’s the reason why aircraft companies pay much closer attention to those parts to ensure a safe journey.
At its core, TOC states that every system has at least one constraint—a limiting factor that prevents it from achieving optimal performance. By identifying and managing this constraint, you can unlock significant improvements.
Goldratt famously used a factory floor as an example (once again, do read the book!), but the principles apply across industries and organizational levels. Whether it’s a slow approval process, understaffing, or a technological bottleneck, the goal of TOC is to maximize throughput by focusing on the constraint.
How the Theory of Constraints Works
The TOC framework revolves around five focusing steps:
Identify the Constraint: Find the bottleneck that limits your system’s performance. It could be a physical limitation, like a machine with limited capacity, or an intangible one, like a policy or cultural resistance.
Exploit the Constraint: Make the most of the constraint without expensive upgrades. For instance, if one team member is the sole approver for critical decisions, prioritize their tasks to reduce delays.
Subordinate Everything to the Constraint: Align all processes and resources to support the constraint. This may mean reorganizing workflows or reallocating team responsibilities.
Elevate the Constraint: If the constraint is still limiting performance, explore long-term solutions like hiring additional staff, investing in new tools, or revising policies.
Repeat the Process: Once the constraint is resolved, a new one will emerge. Continuous improvement is the name of the game.
TOC can transform the way you solve problems by enabling you to narrow your focus on what matters the most.
Real-Life Scenarios
TOC isn’t just for manufacturing; its principles can be applied across industries and functions. For inspiration, below are some real-life scenarios across industries.
1. Manufacturing: Breaking Through Production Line Bottlenecks
Scenario: A factory producing consumer electronics faced recurring delays. One critical machine in the production line had limited capacity, causing a backup of materials. Despite having additional machines downstream, the overall throughput was constrained by this single bottleneck.
Application of TOC:
Step 1: Identify the Constraint: The team analyzed the production workflow and pinpointed the machine as the bottleneck.
Step 2: Exploit the Constraint: They maximized the uptime of the machine through proactive maintenance and rescheduled tasks to ensure it operated without interruptions.
Step 3: Subordinate Everything: Downstream processes were adjusted to match the machine’s output, preventing overproduction and waste.
Step 4: Elevate the Constraint: The company eventually invested in an upgraded machine with higher capacity.
Result: By systematically addressing the bottleneck, the factory increased production efficiency by 25% without hiring additional staff or adding more shifts.
2. Software Development: Streamlining Code Review Processes
Scenario: A tech startup struggled with slow software releases. Although the developers completed their work on time, the code review process became a bottleneck, delaying deployments.
Application of TOC:
Step 1: Identify the Constraint: Using the code review dashboards, the team realized that a single senior engineer handled most code reviews.
Step 2: Exploit the Constraint: They prioritized critical features and assigned review slots to the senior engineer, ensuring high-priority code was reviewed first.
Step 3: Subordinate Everything: Junior engineers were trained to handle routine reviews, leaving only complex issues for the senior engineer.
Step 4: Elevate the Constraint: Over time, the team introduced automated testing tools to reduce the manual workload of code reviews.
Result: The startup reduced its time-to-deployment by 40%, allowing faster response to customer feedback.
3. Sales Teams: Shortening Lead Conversion Cycles
Scenario: A SaaS company’s sales process was hampered by long lead times. Contracts required multiple approvals, slowing down the conversion of leads to paying customers.
Application of TOC:
Step 1: Identify the Constraint: The sales team identified the contract approval process as the primary bottleneck.
Step 2: Exploit the Constraint: The company standardized contract templates for common scenarios, reducing the need for extensive legal reviews.
Step 3: Subordinate Everything: Sales reps were instructed to guide customers through the new streamlined approval process to prevent additional delays.
Step 4: Elevate the Constraint: They implemented an e-signature platform, further speeding up contract finalization.
Result: The time required to close deals was cut in half, boosting the company’s quarterly revenue by 20%.
4. Healthcare: Improving Patient Flow in Hospitals
Scenario: A hospital emergency department faced overcrowding, with patients waiting hours to be seen by doctors. The primary constraint was the availability of diagnostic imaging services like X-rays and CT scans.
Application of TOC:
Step 1: Identify the Constraint: Analysis revealed that delays in imaging were the key bottleneck.
Step 2: Exploit the Constraint: The hospital prioritized emergency cases and scheduled routine imaging during off-peak hours.
Step 3: Subordinate Everything: Staff schedules and patient flow processes were reorganized to support the imaging department’s capacity.
Step 4: Elevate the Constraint: The hospital invested in an additional imaging machine and hired trained technicians.
Result: Patient wait times were reduced by 30%, and the emergency department’s capacity increased, improving overall patient satisfaction.
