Organisational culture is increasingly recognised as a critical driver of performance, leadership effectiveness and long-term business resilience.
Over the course of 2025, as part of Redgrave’s #CultureHeroes series, we spoke with senior leaders across a range of sectors who are actively shaping the environments in which their organisations operate. While their contexts differed, there was clear alignment in how they viewed culture: not as an abstract concept or a set of initiatives, but as something that directly influences how effectively organisations perform.
Many leaders described culture as the cumulative effect of how decisions are made, how work flows through the organisation, and what leaders consistently prioritise.
What stood out was not a shared vocabulary or set of principles, but a shared understanding of cause and effect. The way culture is shaped – through leadership decisions, operational discipline and everyday behaviour – directly influences execution, performance and organisational resilience.
Several leaders reflected that culture often evolves by default unless leadership teams actively shape it. In this sense, culture is not separate from the way an organisation runs; it is embedded in the design of work itself.
In high-performing organisations, culture is treated deliberately, reinforced through consistent behaviours and systems, with close attention on how people experience the organisation – as employees, customers and partners.
Leaders consistently linked intentional culture to stronger outcomes: sharper execution, clearer decision-making, stronger retention and more resilient financial performance. Many emphasised the importance of making culture visible – through observation, dialogue and increasingly through measurement – so it could be discussed and acted on with the same rigour as other performance drivers.
Across these conversations, three factors emerged as the strongest influences on organisational culture. Together they shape how expectations are set, how work happens, and which behaviours endure over time:
01
First, leadership behaviour
The actions leaders take, particularly under pressure, set the reference point for what is expected and accepted across the organisation.
02
Second, how work is designed
Organisational structure, decision rights, approval layers and operating processes shape how work flows and how people behave day to day.
03
Third, what organisations reward and reinforce.
Incentives, performance expectations, promotion decisions and measurement frameworks signal which behaviours are recognised and sustained over time.
Together, these factors make culture visible. They shape how quickly decisions are made, how accountability is experienced, and ultimately how effectively organisations perform.
1. Leadership Behaviour Sets the Reference Point
One theme came through consistently: culture is anchored in leadership behaviour.
Leaders spoke candidly about the role they personally play in shaping expectations – through how they show up, what they prioritise, and what they choose to challenge or overlook. Culture, in this sense, is shaped less by formal statements and more by everyday consistency. Where leaders were clear, visible and aligned, the organisation tended to follow.
At the same time, there was a strong recognition that culture does not sit solely with the leadership team. The most effective organisations were those where responsibility had been consciously shared. Leaders set direction and standards, but culture is ultimately experienced through the work people do each day; through hiring decisions, performance conversations, reward structures, decision rights and customer processes.
Culture is neither an HR-owned initiative nor something that can be delegated and revisited occasionally. It’s a responsibility that becomes everyone’s business through the systems and behaviours leaders choose to put in place.
2. How Organisational Design Influences Culture and Execution
Culture is often discussed in terms of values and purpose, but leaders were clear that it shows up most clearly in the structures, processes and expectations that shape how work gets done each day. Decision rights, approval layers, meeting structures, incentives, performance measures and ways of working all influence behaviour in very practical ways.
While culture is often described as intangible, in practice, it leaves visible signals in behaviour, decision patterns and organisational outcomes.
In many organisations, these systems are inherited rather than intentionally designed, particularly where businesses have scaled quickly, changed ownership or grown through acquisition. Over time, layers of process, reporting lines or control mechanisms accumulate, often introduced for good reasons at the time, but rarely revisited. What begins as sensible oversight can gradually evolve into unnecessary bureaucracy, slowing decisions, diluting ownership and creating friction in how work moves through the organisation.
Equally, when work is designed well – with clarity of accountability, well-defined decision rights and minimal friction, it enables the behaviours organisations value: pace, accountability, collaboration and ownership.
Several leaders highlighted the challenge of scale. In global or decentralised organisations, cultural alignment does not require uniformity. A small set of non-negotiable principles may hold firm, but how work is delivered, and culture is lived will naturally vary by geography, role and context.
Increasingly, leaders are using better data, from employee insights to operational metrics, to understand how culture is experienced across their organisations. When combined with observation and dialogue this allows culture to be surfaced and discussed with the same rigour applied to other drivers of performance.
3. What Organisations Reward and Reinforce
Across the #CultureHeroes conversations, leaders spoke openly about the link between culture and outcomes. Organisations with a clear, well-understood culture found it easier to execute strategy, retain key people, integrate new leaders or acquisitions, and navigate uncertainty.
Culture is reinforced through the systems organisations choose to put in place. Incentives, performance expectations, promotion decisions and measurement frameworks all signal which behaviours are valued and sustained over time.
When these systems align with leadership expectations, culture becomes consistent and self-reinforcing. When they do not, organisations often experience tension between what is said and what is rewarded.
Importantly, leaders were clear that a strong culture isn’t about creating comfort. Rather, it enables challenge, accountability and ambition, while maintaining trust and clarity of direction. Culture was therefore viewed not as separate from performance, but as something that directly shapes execution, risk and long-term financial resilience.
Culture also becomes most visible when leaders face difficult trade-offs – between pace and control, short-term results and long-term capability, or performance and behaviour. How those decisions are handled sends signals across the organisation about what truly matters.
Where culture was less intentional, the impact shows up elsewhere: higher attrition, disengagement, misalignment at the top, and slower execution.
Why Leadership Ownership Matters More Than Culture Initiatives
None spoke about culture as something that could be delivered through a programme alone. While frameworks and initiatives certainly can play a role, what ultimately makes the difference is the leader’s own commitment, and their willingness to model the behaviours they expect to see across the organisation.
Culture work does not end once behaviours are defined. It’s not static. It develops over time as organisations grow, priorities shift and new people join. Without continued attention from leaders, it will inevitably evolve, but not always in the ways intended.
Importantly, leaders did not present this as a pursuit of perfection. Many spoke openly about learning as they went, adjusting course, and acknowledging when things hadn’t worked. What mattered most was consistency and intent over time.
Six Leadership Actions That Strengthen Organisational Culture
Bringing these insights together, several considerations stand out for leaders thinking seriously about cultural impact:
Make culture visible in day-to-day decisions
Look closely at where culture shows up in incentives, performance conversations and decision-making, and where it does not.
Review the systems you’ve inherited
Identify which structures reinforce the culture you want to build, and which ones work against it.
Examine how work is designed
Look beyond people processes to consider decision rights, approval layers and inherited rules that may be slowing execution or diluting accountability.
Keep culture on the leadership agenda
Return to it regularly in board and leadership discussions, rather than treating it as a one-off initiative.
Lead visibly through moments of pressure
How leaders behave during periods of change, tension or trade-offs often shapes culture faster than any formal initiative.
Reassess culture as the organisation evolves
Culture evolves continuously as organisations grow, priorities shift and new people join. Leaders should regularly pause to reflect on how culture is developing, particularly during moments of strategic change, ownership transitions or organisational growth, rather than assuming it will adapt in the ways intended.
What Culture Means for Boards and Leadership Teams
These conversations closely reflect what we see in our work with boards and leadership teams. Culture often becomes most visible during moments that test an organisation; leadership appointments, executive transitions, periods of strategic change, or the integration of new teams following acquisition.
New leaders inevitably interpret existing norms, reinforce some behaviours and challenge others. How thoughtfully organisations manage these transitions can have a significant impact on cultural continuity, leadership alignment and organisational momentum.
These changes can act as catalysts for cultural clarity and can signal a shift in expectations about how the organisation operates.
At Redgrave, we work with leaders who recognise that culture and strategy are deeply connected, expressed through leadership capability, behaviour and judgement.
Whether through executive search, assessment or advisory work, our focus is on helping organisations build leadership teams that create the conditions for strong cultures and lasting outcomes.
The leaders featured throughout our #CultureHeroes series demonstrate that when culture is treated as a serious leadership priority, stronger and more sustainable results tend to follow.
Ultimately, culture is not something organisations automatically have. It’s something leaders need to actively shape through the decisions they make and the environments they create. Ignoring it as a leadership priority does not remove its influence – it simply means leaving one of the most powerful drivers of performance to chance.
This article forms part of Redgrave’s ongoing #CultureHeroes series, capturing insights from leaders who are actively shaping cultures that support performance, resilience and sustainable growth.
