Earlier this month, I spoke to Marciano Hermo about his new book -- Integrating Lean Six Sigma and Automation: A Framework for Transforming Processes in the Digital Age -- which, through a structured integration cycle, real-world examples, and field-tested tools, demonstrates how improvement and technology reinforce, not replace, each other.
During our conversation, I asked him: "Why has it been a struggle to integrate Lean Six Sigma and automation?" Here is his complete answer:
The struggle to integrate Lean Six Sigma and automation is not because the two are incompatible. In fact, they are highly complementary. The difficulty is that organizations have often treated them as separate disciplines.
Lean Six Sigma traditionally sits with operational excellence, quality, or process improvement teams, while automation is commonly driven by IT, digital transformation, or technology groups. Each brings different expertise, priorities, measures of success, and even language. As a result, improvement and automation initiatives can proceed in parallel rather than as part of one transformation journey.
Another challenge is sequencing. Organizations are understandably attracted to the speed and scalability promised by automation. But automating a process before understanding and improving it can simply make waste, complexity, and poor decisions happen faster and at greater scale.
As I emphasize in the book, the objective should not be to automate a process simply because it can be automated. First, understand, challenge, simplify, and improve the process; then use technology where it can create additional, sustainable value.
There is also a human dimension. Lean Six Sigma and automation both change how work is performed. Integration therefore requires more than analytical tools and technology; it requires leadership alignment, cross-functional collaboration, new capabilities, and attention to how people experience and adopt change.
This is why I see Lean Six Sigma and automation not as competing approaches, but as complementary capabilities. Lean Six Sigma helps organizations determine what should change and why. Automation can then help scale, accelerate, and sustain the improved process.
Bringing the two together creates the opportunity to move beyond isolated improvement projects or technology deployments toward a more purposeful approach to process transformation.
Do you agree with Marciano's perspective? Have you tried integrating Lean Six Sigma and automation in your organization? What struggles did you face?
