Why tech managers are earning their Green Belt

A growing number of tech managers are earning their Green Belt. Not for the dojo, but for the operations floor.

While Agile and DevOps methodologies dominate the way teams build and deploy software, they don’t always address the underlying processes that slow delivery, waste resources, or cause recurring quality issues. 

“If the process behind it isn’t optimized, all you’ve done is moved the problem.”

For tech managers facing delays, resource constraints, and recurring quality issues, Lean Six Sigma Green Belt (LSSGB) offers a structured, data-driven approach to fix what’s slowing teams down. 

An LSSGB is trained in a hybrid methodology that blends Lean principles (eliminating waste) with Six Sigma tools (reducing variation and defects). Green Belts lead small to medium-sized process improvement projects or support larger initiatives. 

For startup teams, this means gaining sharper analytical skills and a deeper understanding of where and how to optimize performance.

“Even if you’re doing a huge cloud transformation or an SAP upgrade to the new HANA platform, there are always processes involved,” said Marco Steinmueller, a Senior Tech Consultan, LSSGB Black Belt Practitioner, and Program Advisory Council member for The Chang School’s Postgraduate Certificate in LSSGB. 

“There’s always a need for improvement, and that’s where Lean Six Sigma tools become incredibly valuable.”

Startups often move fast, but sometimes, they move fast in the wrong direction. Without the tools to analyze and improve underlying systems, productivity gains are hard to sustain.

“The mindset is always to look at the big picture,” says Steinmueller. “You can’t just optimize one thing. You need to look at the whole end-to-end stream from the processes to the people to the technology and continuously improve it.”

Optimize, optimize, optimize

From cloud integration to software release cycles, waste can creep into even the most modern workflows. Lean Six Sigma offers tools like Value Stream Mapping to visualize processes, identify inefficiencies, and enhance quality.

“You add value at every step, or you don’t do it,” says Steinmueller. “If there’s no value, it doesn’t belong in the workflow.”

This philosophy applies whether you’re rolling out an internal platform or optimizing customer support response times.

In resource-constrained environments, which most startups are, Lean Six Sigma helps also teams do more with less.

“There are a lot of layoffs, tight margins, and underutilized resources, especially in cloud environments,” says Steinmueller. “Lean Six Sigma helps you look critically at where your money is going, and what value each process or resource adds.”

This mindset is critical when navigating legacy systems, technical debt, or cloud migrations.

“You can’t just lift and shift your old systems to the cloud and expect magic,” he notes. “If the process behind it isn’t optimized, all you’ve done is moved the problem.”

Back decisions with data

Using the Define, Measure, Analyze, Improve, Control framework, tech managers can diagnose operational bottlenecks and implement fixes grounded in real-time data.

“One powerful combination we’re seeing is traditional lean tools paired with newer technologies like process mining,” says Steinmueller. “You get live data, not just historical insights, and can act fast on what the data is showing you.”

This helps managers answer critical questions: Are we allocating resources effectively? Where are we seeing the most defects? How can we streamline delivery?

Deliver faster

Agile teams focus on iteration. DevOps teams focus on deployment. Lean Six Sigma helps both reduce recurring errors and improve outcomes over time.

“Lean Six Sigma can help reduce sprint cycle times, improve delivery speed, and support root cause analysis,” Steinmueller explains. “It goes deeper than a retro meeting. It helps teams understand why something happened and how to prevent it.”

He adds that while Agile focuses on getting the MVP out the door, Lean Six Sigma supports long-term optimization and resilience.

Whether you’re building hardware, software, or hybrid products, Lean Six Sigma can ensure user needs are baked into the process early.

“You get the perspective of software, hardware, and user requirements and bring them together to innovate and ensure quality,” says Steinmueller.

By focusing on upstream quality and cross-functional collaboration, startups can reduce rework and deliver better products faster.

Foster a culture of continuous improvement

Lean Six Sigma is as much a mindset as it is a toolkit.

“The beauty of the Green Belt level is you’re hands-on. You’re on the floor, working in real time, testing, adjusting, improving,” says Steinmueller. “It’s a great starting point for anyone looking to bring measurable value to their role.”

Steinmueller added that Green Belts don’t need to lead massive enterprise-wide transformations but rather improve workflows, mentor peers, and deliver tangible wins.

“You won’t change the whole world with one project,” he said, “but you’ll build experience and momentum. And that’s how innovation scales.”
