Lean six sigma in 2025: 5 trends every business leader should know

In today’s fast-moving business landscape, the ability to improve processes, cut waste, and boost efficiency is more critical than ever.

That’s where Lean Six Sigma continues to prove its value — especially in 2025, as new technologies and workplace challenges reshape how businesses operate. From AI to sustainability,

Lean Six Sigma is evolving rapidly. Here are five key trends in Lean Six Sigma that every senior leader should be paying attention to — and how upskilling your team can keep you ahead of the curve.

1. Ai and data analytics are enhancing process improvement

AI and machine learning are no longer buzzwords — they’re tools that are transforming how businesses approach process improvement. In 2025, many organisations are integrating AI-driven analytics into their Lean Six Sigma strategies to detect patterns, predict bottlenecks, and automate root cause analysis.

✅ Leadership takeaway: Businesses that combine Lean Six Sigma methodology with AI tools are gaining faster insights and driving measurable performance gains.

2. Agile and lean are converging

In tech-driven industries, Lean and Agile have started to blend. The traditional structure of Lean Six Sigma is being adapted to meet the faster, iterative cycles of Agile. This “hybrid” approach is ideal for modern teams delivering digital products or rapid service innovation.

✅ Leadership takeaway: Training your team in both Lean Six Sigma and Agile methodologies can foster a culture of continuous improvement and innovation.

3. Sustainability and esg goals are tied to lean outcomes

With ESG (Environmental, Social, Governance) and net-zero commitments high on the corporate agenda, Lean Six Sigma is now being used to identify and reduce wasteful or unsustainable practices — from energy usage to excess materials.

✅ Leadership takeaway: Process improvement is no longer just about saving time and money — it’s also about meeting corporate sustainability goals.

4. Soft skills are the new core competencies

While Lean Six Sigma has traditionally focused on data and process tools (DMAIC, fishbone diagrams, etc.), 2025 leaders are increasingly valuing soft skills like change management, coaching, and cross-functional communication.

✅ Leadership takeaway: Developing well-rounded leaders who can drive improvement across teams is just as important as technical know-how.

5. Apprenticeships are upskilling the next generation of leaders

As businesses navigate an ageing workforce and growing digital skills gap, many are turning to leadership apprenticeships — including those focused on Lean Six Sigma — to build talent pipelines.

These structured programmes combine on-the-job training with formal qualifications and allow businesses to shape future leaders who understand how to improve performance and embed a culture of continuous improvement.

✅ Leadership takeaway: If you’re serious about business efficiency, investing in leadership training through apprenticeships is a powerful, cost-effective solution.
