Operational excellence does not survive on tools alone. It is not sustained by templates, dashboards, daily meetings, Lean events, or improvement slogans. Those things can support performance, but they do not sustain it. What sustains operational excellence over time is leadership behaviour.
That matters even more now because modern operational excellence is broader than classic cost and efficiency programmes. McKinsey’s recent work describes next-generation operational excellence as combining lean principles, investment in people, and the use of technology for collaboration, while the European Commission’s Industry 5.0 framing emphasises human-centricity, resilience, and sustainability. In parallel, the World Economic Forum’s Future of Jobs Report 2025 identifies analytical thinking, resilience, flexibility, agility, leadership, and social influence among the most important core skills employers value.
In other words, operational excellence today is not just about improving process performance. It is about creating an environment where good process performance can be repeated, adapted, and sustained. That only happens when leaders behave in ways that make disciplined improvement part of everyday management.
1. Leaders stay close to the work
One of the most important sustaining behaviours is staying connected to what is really happening in the operation. Leaders who sustain operational excellence do not manage only through reports. They spend time close to the process, ask practical questions, and pay attention to where work becomes difficult, inconsistent, or overloaded.
This matters because dashboards and summaries can hide the lived reality of the operation. A process can look stable in a report while frustration, workarounds, delays, and small failures accumulate underneath. McKinsey’s operational-excellence work continues to stress that technology and data should support better collaboration and performance, not replace real understanding of how work gets done.
Leaders who stay close to the work make better decisions because they see the gap between formal process and actual process. They are more likely to notice whether problems are structural, whether standards are usable, and whether teams are being asked to carry too much hidden complexity.
2. Leaders ask better questions than “Are we on track?”
Operational excellence weakens when leadership conversations become too focused on status updates. Leaders who sustain excellence ask questions that improve thinking, not just reporting.
They ask:
What is driving this result?
What evidence supports that conclusion?
Where is the recurring failure mode?
What is the team struggling with that the metrics do not show?
Are we treating the cause or only the symptom?
This kind of questioning matters because analytical thinking remains the top core skill identified by employers in the World Economic Forum’s 2025 report. Sustained operational excellence depends on that same discipline: looking beyond surface indicators and challenging assumptions before acting.
Good leaders do not create fear through questioning. They create clarity. Their questions raise the quality of diagnosis and prevent teams from mistaking activity for improvement.
3. Leaders build people, not just processes
Many organisations say people matter, but leadership behaviour reveals whether that is actually true. Leaders who sustain operational excellence invest in the capability of the workforce, not only in the performance of the system.
McKinsey’s next-generation operational-excellence perspective explicitly includes investing in people as a core part of excellence, not a side issue. The Industry 5.0 framework also places the wellbeing of workers at the centre of industrial transformation rather than treating workers as secondary to technology and output.
In practice, this means leaders coach problem-solving, support skill development, create opportunities for learning, and treat capability-building as part of operational performance. They do not assume that process discipline will sustain itself if people are underprepared, disengaged, or excluded from improvement. They understand that stable performance depends on capable people making sound decisions every day.
4. Leaders reward honesty over theatre
Operational excellence becomes performative when leaders unintentionally reward appearances more than truth. Teams learn very quickly whether leadership wants real transparency or polished updates.
Leaders who sustain excellence make it safe to surface problems early. They do not punish people for exposing weakness in the system. They do not create pressure to make every metric look positive. Instead, they reward realism, evidence, and timely escalation.
This matters in a more complex operating environment where resilience and adaptability are increasingly central to performance. The World Economic Forum highlights resilience, flexibility, and agility as leading skills, and the Industry 5.0 agenda places resilience at the heart of the future industrial model. Those priorities are hard to achieve in cultures where people hide problems until they become too large to ignore.
A leader who says “bring me the truth early” does more for operational excellence than a leader who simply asks for higher targets.
5. Leaders are consistent when priorities compete
Operational excellence often weakens not because leaders disagree with it, but because they abandon it under pressure. When deadlines tighten, customer demands rise, or disruptions appear, some leaders revert to firefighting, bypass standards, and reward short-term heroics over stable process control.
The leaders who sustain excellence behave differently. They remain consistent when pressures compete. They make trade-offs consciously. They protect the discipline of the operating system even when conditions are difficult.
This is increasingly important because operations now sit at the center of wider transformation efforts. McKinsey’s 2026 operations commentary described operations as the engine of transformation, while its 2025 operations outlook highlighted cross-functional collaboration and curiosity as productivity enablers. Sustaining excellence therefore requires leadership behaviour that remains steady across change, not just during stable periods.
Consistency sends a powerful message: standards matter even when the environment is uncomfortable.
6. Leaders connect technology to purpose
In many organisations, digital tools are introduced as if the value is self-evident. But sustained operational excellence requires leaders to connect technology to the real purpose of the operation: better decisions, better flow, better quality, stronger resilience, and more effective collaboration.
McKinsey’s operational-excellence work describes technology as something to use for collaboration, not as a substitute for management discipline, while Industry 5.0 frames technology within wider human and societal goals.
The leadership behaviour that matters here is interpretation. Strong leaders do not ask teams to admire dashboards, AI tools, or new systems for their own sake. They keep returning to practical questions: What is this helping us do better? What friction has it removed? What new risks has it introduced? Is it helping people perform better, or only generating more data?
That behaviour prevents digital transformation from drifting into digital activity without operational value.
7. Leaders think cross-functionally
Operational excellence breaks down when leadership stays trapped inside silos. Many of the biggest operational problems are not owned by one function alone. They sit in handoffs, interfaces, conflicting incentives, and weak coordination across departments.
McKinsey’s 2025 operations insights specifically point to cross-functional collaboration as a key ingredient of productivity, and its broader operating-model research argues that shortcomings in operating models often explain the gap between strategic ambition and real delivery.
Leaders who sustain operational excellence therefore behave like integrators. They connect teams, align priorities, reduce fragmentation, and avoid local optimisation that damages overall flow. They do not ask only, “Is my area performing?” They ask, “Is the system performing?”
That shift is crucial because excellence cannot be sustained in one department while dysfunction persists between departments.
8. Leaders create learning loops, not just control loops
A lot of leadership behaviour in operations is based on control: review the metrics, check compliance, close the actions, follow the plan. Control matters, but it is not enough to sustain excellence.
Leaders who sustain operational excellence create learning loops as well. They make time to reflect on what is working, what is recurring, what assumptions were wrong, and what the organisation needs to understand more deeply. They treat deviations, missed targets, and implementation failures as opportunities to learn, not only as issues to close.
This aligns with the broader move toward more adaptive, resilient organisations. McKinsey’s leadership and operating-model work emphasises that high performance depends on how organisations translate strategy into behaviour and capability, while the WEF skills outlook highlights adaptability and leadership alongside analytical thinking.
Sustained excellence depends on an organisation that gets better at learning, not only better at monitoring.
9. Leaders model curiosity and humility
One of the least discussed leadership behaviours is humility. Leaders who sustain operational excellence do not assume that hierarchy guarantees understanding. They remain curious. They are willing to be corrected by the process, by the data, and by the people closest to the work.
McKinsey’s 2025 operations outlook explicitly highlights curiosity as part of what helps companies power productivity. That is not a soft idea. Curiosity is what helps leaders see weak signals, explore alternatives, and avoid becoming trapped by their own assumptions.
Humility matters for the same reason. Leaders who believe they already understand the operation stop learning from it. Leaders who remain open create better dialogue, better diagnosis, and better improvement.
10. Leaders make operational excellence part of culture, not a programme
The final behaviour is perhaps the most important: leaders treat operational excellence as part of how the organisation is run, not as a temporary initiative.
When excellence is treated like a programme, it depends on momentum, sponsorship, and special attention. When leadership changes or priorities shift, it fades. But when leaders consistently model the right behaviours, operational excellence becomes embedded in everyday culture. It shapes how meetings are run, how problems are escalated, how decisions are made, how people are developed, and how trade-offs are handled.
That broader cultural view is consistent with both next-generation operational excellence and Industry 5.0 thinking, which each imply that enduring performance requires more than technical tools. It requires a management system and leadership approach that support people, resilience, collaboration, and continuous improvement over time.
Conclusion
The leadership behaviours that sustain operational excellence are not dramatic. They are disciplined. Leaders stay close to the work, ask better questions, build people, reward honesty, stay consistent under pressure, connect technology to purpose, think across functions, create learning loops, and model curiosity.
These behaviours matter because operational excellence is no longer just about local efficiency. In today’s environment, it sits at the intersection of productivity, digital transformation, workforce capability, and resilience. Research from McKinsey, the World Economic Forum, and the European Commission all points in the same direction: sustainable performance depends on the quality of leadership behaviour as much as the quality of operational tools.
Without the right leadership behaviours, operational excellence becomes a set of activities. With them, it becomes a durable way of running the business.
