Redefining Excellence: From Maturity to Mastery
March 3, 2026 – Mike Martyn
For more than four decades, the Shingo community has played a critical role in shaping how organizations think about excellence. By grounding improvement in principles, systems, and behavior, the Shingo Model has elevated the conversation beyond tools and outcomes toward culture and leadership. Over the past twenty years, I have had the opportunity to work alongside many organizations committed to that journey, helping leaders translate the Shingo Guiding Principles into daily practice and sustainable results.
Excellence is not a static concept. It changes as organizations grow, as leadership transitions, and as expectations expand. What qualifies as excellence for a growing enterprise is not the same as what is required for an organization operating across regions, generations, and increasingly uncertain conditions. Early on, the focus is understandably on performance, stability, and credibility. As systems mature and behaviors become more consistent, attention shifts toward alignment and sustainability. Yet many organizations continue to pursue definitions of excellence that served them well in an earlier chapter, even as the context around them shifts. Eventually—particularly in large and complex organizations—a different question surfaces quietly in the background:
How do we ensure that excellence continues to evolve rather than solidifying into standards that can be maintained but no longer challenged?
In practice, this evolution often becomes visible through three distinct phases. The first is industry excellence, where performance and results establish credibility. Industry excellence is measured through quality, delivery, cost, efficiency, and customer satisfaction. Organizations that achieve industry excellence earn their position through disciplined execution and technical capability. They deliver reliably under pressure and build reputations as partners others can depend on. This form of excellence is real, measurable, and hard earned.
Industry excellence answers important questions: Are we competitive? Are we delivering results? Are customers confident in our ability to perform? These questions matter, and organizations that cannot answer them do not survive. Over time, however, industry excellence tends to emphasize outcomes more than the conditions that produce them. Performance remains strong, but leadership depth does not always scale at the same pace. Succession becomes a concern rather than a system. Variation increases as organizations grow.
The second evolutionary phase is Shingo excellence, where principles, systems, and behaviors create maturity and stability. The Shingo Model expands the definition of excellence by shifting attention from results alone to include the relationship between principles, systems, and behaviors. It asserts that sustainable success depends not only on what an organization achieves but on how it achieves those results—every day. From this perspective, culture is not an aspiration or a set of values on the wall; it is the visible evidence of consistent, principle-based behaviors reinforced through intentional system design.
The Shingo Guiding Principles define “the maturity of excellence.” They establish a disciplined standard for organizational behavior, emphasizing respect for every individual, leadership humility, scientific thinking, focus on process, quality at the source, flow and pull, constancy of purpose, value for the customer, and systems thinking. Together, these principles provide a coherent framework for building organizations that are stable, aligned, and capable of sustaining results over time. For many organizations, embracing Shingo maturity represents a critical evolution. Even where strong operational systems already exist, the Shingo Model makes explicit the role of leadership behavior and cultural alignment. It creates a shared language that connects strategy to daily work and helps leaders see gaps between current practices and the behaviors required for long term excellence. Over time, heroics are replaced by systems, and inconsistency gives way to shared expectations. Maturity brings confidence, and systems function as intended. Leaders speak a common language, and results become predictable.
Yet, as organizations mature, a subtle shift often occurs. The same structures that once accelerated learning begin to standardize it. The same systems that created clarity begin to constrain experimentation. What once felt like progress begins to feel like maintenance. This is not a failure of the Shingo Model. It is a reflection of what maturity is designed to do. Maturity excels at refinement and consistency. It strengthens what exists. But maturity does not inherently compel organizations to question the boundaries of the framework itself. It sustains excellence as defined. It does not automatically evolve that definition. It perfects what already exists instead of asking what must change.
Striving for mastery represents a fundamental shift in intent. This phase tends to emerge more slowly and with less clarity, shaped by questions of legacy, scale, and endurance. It is in this third phase that excellence itself must be redefined. Here, an organization moves from optimizing within a known definition of excellence to deliberately challenging and expanding that definition. This shift does not reject the Shingo Model; it depends on it. The discipline and alignment established through Shingo maturity create the foundation upon which mastery becomes possible, but mastery requires a different governing lens.
The ten guiding principles of the Shingo Model define the maturity of excellence. At my company, there are a further five transformational principles that define its mastery. These five principles, which emerged from practice rather than theory, were shaped by the realities of scale, the demands of succession, and the ambition to build something capable of enduring beyond any single leader.
Contribute to Society: Mastery begins when an organization looks beyond its own performance and defines excellence in terms of the value it creates for the broader system in which it operates. This perspective shifts decision making from short-term optimization toward long-term contribution and anchors excellence in purpose rather than achievement.
Embed a Philosophy: Mature organizations often articulate values and principles, but mastery requires a deeply internalized philosophy that guides behavior even in the absence of rules or oversight. Embedding a philosophy means aligning leadership development, system design, and daily management around shared beliefs about the role of leaders and the experience of work.
Design for Experience: Excellence at scale cannot rely on individual interpretation. The experience of being a leader, team member, or customer must be intentionally designed and reinforced through systems and behaviors. Mastery recognizes that experience is not a byproduct of performance but one of its primary drivers.
Drive Innovation: Maturity focuses on consistency and control. Mastery demands curiosity and experimentation. In this context, innovation is not limited to products or technology; it includes leadership practices, system design, and the way learning occurs across an organization.
Learn Continuously: Mastery is never static. It requires organizations to treat learning as a core capability rather than an occasional activity. This means creating systems that accelerate learning, normalize reflection, and encourage adaptation at every level.
Together, these five transformational principles define the mastery of excellence. They do not replace the Shingo Guiding Principles—they build on them. While the Shingo Guiding Principles are essential to achieving maturity, the five transformational principles are essential to transcending it.
The pursuit of mastery is not reserved for organizations at the end of their journey. Mastery is a mindset that shapes how excellence is defined from the beginning. Organizations that wait to think about mastery until after they achieve maturity often find themselves constrained by the very systems they worked so hard to build. Excellence that is intentionally redefined can endure across leaders, generations, and changing conditions. That distinction marks the difference between achieving excellence and mastering it.
