How Lean Six Sigma Shapes My Leadership

Last weekend marked an important milestone in my leadership journey.
I officially became a Certified Lean Six Sigma Champion.
While the certification is worth celebrating, what matters far more is what Lean Six Sigma represents.
Lean Six Sigma is a mindset of continuous improvement, clarity, efficiency, and people-centred problem-solving.
It’s not just a methodology.
It’s a leadership philosophy.
Over the years, I’ve seen firsthand how it can transform healthcare systems, teams, and outcomes, and how the same principles can drive success in almost every other industry.
Why Lean Six Sigma Matters in Leadership
At its core, Lean Six Sigma focuses on two simple but powerful goals:
Eliminating waste
Reducing variation and errors
In leadership terms, that means:
Clearer processes
Better decisions
Improved outcomes
Happier teams
Stronger customer or patient experiences
But more importantly, it teaches leaders to move from reacting to problems to systematically solving them.
Instead of firefighting every day, you build systems that prevent fires in the first place.
How I Use Lean Six Sigma as a Healthcare Leader
Healthcare is one of the most complex industries in the world.
This industry has
Multiple stakeholders.
High risk.
Tight resources.
Lives at stake.
And yet many healthcare challenges are not clinical problems.
They are process problems.
Over the years, I’ve applied Lean Six Sigma principles in several ways:
1️⃣ Improving Patient Flow
In many hospitals, patients experience long waiting times not because staff are slow, but because systems are inefficient.
By mapping patient journeys and identifying bottlenecks, we can:
Reduce delays
Improve bed utilisation
Enhance patient experience
Small process changes often lead to massive improvements in outcomes.
2️⃣ Reducing Errors and Rework
Medication errors, documentation mistakes, and repeated tests are costly in both financial and safety terms.
Lean Six Sigma tools help:
Identify root causes
Standardise best practices
Reduce variation
The result is safer care and more reliable systems.
3️⃣ Supporting Burnt-Out Teams
When processes are chaotic, people burn out.
By simplifying workflows and removing unnecessary steps, teams:
Work smarter
Feel more in control
Experience less stress
Operational excellence is also a form of compassion.
Lean Six Sigma Beyond Healthcare: Where It’s Making an Impact
While it started in manufacturing, Lean Six Sigma now drives excellence across many industries.
Here are a few examples you may relate to:
Manufacturing
This is where Lean Six Sigma became famous.
Companies use it to:
Reduce defects
Improve production speed
Lower costs
Increase quality
From car production to electronics, it ensures consistency and efficiency at scale.
Finance & Banking
Banks apply Lean Six Sigma to:
Reduce loan processing time
Minimise errors in transactions
Improve customer service
For example, some banks have cut mortgage approval times from weeks to days simply by streamlining processes.
Logistics & Supply Chain
In logistics, small inefficiencies quickly become expensive.
Lean Six Sigma helps:
Optimise delivery routes
Reduce inventory waste
Improve turnaround times
Companies such as courier services and retailers use it to meet customers’ expectations quickly.
Retail & E-commerce
Retailers apply Lean Six Sigma to:
Improve checkout processes
Reduce stockouts
Enhance customer experience
Better systems mean happier customers and higher profitability.
Technology & Startups
Even tech companies use Lean Six Sigma thinking to:
Improve product development cycles
Reduce bugs
Streamline onboarding
Agile and Lean principles often work hand in hand.
The Leadership Lesson Across All Industries
Here’s the truth many leaders miss:
Most performance problems are not people problems.
They are process problems.
Lean Six Sigma teaches you to ask:
Where is waste hiding?
Where are errors coming from?
Where does work get stuck?
What can be simplified?
When you fix the system, people naturally perform better.
What Becoming a Champion Means to Me
Earning this certification is not about adding another title.
It’s about deepening my ability to:
Lead operational transformation
Build efficient systems
Support high-performing teams
Deliver better outcomes in healthcare and beyond
As a healthcare leader, executive coach, and strategist, Lean Six Sigma strengthens how I help organisations grow sustainably.
A Simple Lean Six Sigma Exercise for This Week
Try this quick leadership reflection:
Pick one process in your work that frustrates people.
Ask:
Where does the delay happen most?
Where do mistakes repeat?
Which steps add no real value?
Even identifying one improvement can unlock significant efficiency gains.
Lean Six Sigma is not just for factories.
It’s for leaders who want clarity over chaos, systems over stress, and improvement over firefighting.
Whether you’re in healthcare, finance, tech, education, manufacturing, or entrepreneurship, the principles remain powerful.
As I step into this new chapter as a Certified Lean Six Sigma Champion, I’m more convinced than ever that outstanding leadership is built on great systems.
And great systems are built intentionally.
