Research shows that many Lean initiatives fail to achieve lasting effect. The cause rarely lies in the methods, but in how the implementation is approached. This article reviews the factors research points to as decisive for success.
Change is not an event
One of the most frequent mistakes is to treat Lean as a project with a start and end date. Workshops are held, future value streams are drawn — and then the organisation is expected to drive the implementation itself. Research from MIT and LEI, among others, shows that this approach rarely creates lasting change.
The three factors the research highlights
When we analyse the implementations that actually hold, we find three recurring factors in the literature:
1. Management behaviour before tools
- •Managers who use the boards themselves every day — not just check in
- •Visible prioritisation of improvement work in management's calendar
- •Consistent follow-up on deviations
- •Mistakes treated as learning, not blame
2. Governance structures that create rhythm
- •Daily Management with clear escalation paths (Tier 1-2-3)
- •Weekly improvement meetings with a fixed agenda
- •Monthly review of KPI development with the leadership team
- •Quarterly strategic adjustment of the improvement portfolio
3. Capability building in the organisation
- •Internal improvement leaders trained to drive the process
- •Frontline managers with practical Lean experience
- •Documented standards that can be handed over
- •Ongoing coaching until the behaviour is self-sustaining
The execution gap in practice
A typical scenario: a company decides to implement Daily Management with board control. They put up boards, train the team leaders, and run the first weeks with high energy. But then an urgent situation arises. The board meetings are skipped. When they resume, the data is out of date. The team leaders lose faith in the system. This pattern is well documented in the Lean literature.
This is precisely why we at Prozanta work in phases — map, build, execute, anchor, and stay in operations until the improvement runs without us. A practical entry point to the governance part can be found in our guide to Daily Management.
✓Concrete takeaways
- →Measure anchoring, not just implementation — track whether the behaviour holds over time
- →Build governance before tools — the Daily Management structure matters more than which Lean method you choose
- →Plan for resistance — what do you do when everyday pressure squeezes the improvement work?
- →Invest in internal improvement leaders — external expertise should be transferred, not rented permanently
