The Leadership Habit That Makes Lean Six Sigma Programs Succeed

By Ed Hutton, Lean Six Sigma Australia — operating since 2016, 1,000+ Lean Six Sigma certifications delivered, 90% completion rate

In short: Lean Six Sigma programs succeed or fail based on whether executives actively sponsor them — protecting time, resolving conflicts, and staying visibly engaged — not on whether Belts are well trained. LSSA’s Leadership / Executive Alignment Program is a two-session package (an Executive Briefing before certification starts, and an Executive Check-In a few months in) built to make that active sponsorship happen by design, not by chance.

You’ve seen the pattern before, even if you haven’t put a name to it. A Lean Six Sigma cohort gets certified. The launch has energy — a kickoff, a business case, a handful of promising pilot projects. Then, six or twelve months later, the projects have quietly lost momentum, the Belts are back to their day jobs, and the whole thing gets filed under “we tried that once.”

The usual explanation is a skills problem: not enough training, not enough rigour, the wrong tools. But that’s rarely what’s actually going on.

The research points somewhere else

Prosci, whose change management benchmarking research spans more than two decades and tens of thousands of participants, has asked organisations the same question in study after study: what separates change initiatives that succeed from the ones that don’t? Sponsorship — not employee engagement, not communication, not methodology — has consistently come out on top as the single biggest contributor to success. Their data shows projects with effective sponsorship and change management are roughly seven times more likely to meet their objectives than those without it.

That finding holds specifically for Lean Six Sigma, too. Academic research into LSS deployments (published through the IEOM Society) names “lack of leadership” among the most common causes of failure, and makes a point worth sitting with: leadership and cultural readiness are too often treated as an afterthought to the technical rollout, when they’re the part that determines whether any of it sticks.

None of this is really about hostile leadership, or leaders who don’t believe in the program. It’s about a specific, common, and easy-to-miss failure mode: passive approval standing in for active, visible championship.

Endorsement isn’t sponsorship

There’s an important distinction buried in that failure mode, and it’s easy to miss because both versions look identical at the kickoff meeting.

A leader who endorses a program signs the business case, shows up to the launch, says the right things, and then goes back to running the business. A leader who sponsors a program does something different: they protect the time their people need to work on it, they personally remove the obstacles that stall projects, they resolve the competing priorities that inevitably come up between departments, and they make a visible point of recognising progress — not just at the end, but along the way.

The gap between those two postures is where most stalled programs actually die. Not in the training room — in the six months after it, when nobody with real authority is actively keeping the program alive.

The “messy middle”

There’s a specific place this shows up: the layer of managers between the executive sponsor and the Belts doing the project work. They’re often caught between two masters — support the improvement project, and hit the KPIs they’re actually measured on, which frequently pull in different directions. That tension is real, it’s predictable, and it’s not something a Belt-level project lead can resolve on their own. It needs someone with the authority to actually adjudicate competing priorities. That’s a leadership job, not a training gap.

Where most Lean Six Sigma rollouts leave a hole

Most organisations investing in Lean Six Sigma put real time and budget into training their Belts — and rightly so. What’s far rarer is any equivalent investment in preparing the leadership team for what active sponsorship actually requires of them, week to week, once the training is over. The result is a program that’s technically well-resourced and structurally unsupported at exactly the level that determines whether it survives contact with the rest of the business.

That’s the gap worth closing directly, rather than hoping leadership figures it out on its own.

What we’re introducing: the Leadership / Executive Alignment Program

Two short, live sessions, built specifically to convert leadership approval into leadership action:

• An Executive Briefing, delivered before a certified Belt cohort begins — a clear, non-technical grounding in what Lean Six Sigma can do for the business, and, more importantly, what active sponsorship looks like day to day. Executives leave having personally committed to a project or area they’ll sponsor, not just having attended a presentation.
• An Executive Check-In, delivered a few months into deployment — an accountability moment. Real project progress gets reviewed, blockers get surfaced while they’re still fixable, and the group agrees what it takes to protect early wins so they don’t quietly revert once attention moves elsewhere.

It’s deliberately not another course. It’s a structured way to make sure the leadership commitment a Lean Six Sigma program depends on is actually built in from the start — not assumed, and not left to chance.

If stalled improvement momentum sounds familiar, we’d be glad to talk about how this fits alongside your team’s Lean Six Sigma program.

Frequently asked questions

Why do Lean Six Sigma programs fail?

Most commonly because of leadership, not skills. Research on Lean Six Sigma deployments consistently names a lack of active leadership as a top failure cause, and separate change management research shows executive sponsorship is the single biggest contributor to whether a program succeeds — ahead of training, communication, or methodology.

What’s the difference between executive sponsorship and executive approval?

Approval is a leader signing off on a program and attending the launch. Sponsorship is active: protecting the team’s time, removing obstacles, resolving competing priorities between departments, and visibly recognising progress throughout the program — not just at the start.

What does an effective Lean Six Sigma sponsor actually do?

• Protects the time their Belts and project teams need to do the work.
• Personally removes obstacles that stall projects.
• Resolves competing KPIs between departments that would otherwise derail a project.
• Visibly recognises progress along the way, not only at completion.

How can a leadership team prepare to sponsor a Lean Six Sigma program?

The Leadership / Executive Alignment Program is built for exactly this: an Executive Briefing before a certified Belt cohort begins, and an Executive Check-In a few months into deployment, so sponsorship behaviours are established up front and reinforced while the program is running — rather than assumed and left to chance. And it asks for the executive’s time, not a Belt-level commitment: two focused sessions, not the multi-week certification curriculum built for the people actually running the projects.
