Company culture is the living DNA of an organisation, a system of truly lived values that structures daily life. It is expressed in the management style, in the way teams communicate, in collective rituals – meetings, feedback, celebrations – and above all in the implicit norms that guide decisions: how we decide, how we handle mistakes, how we debate ideas.

In reality, culture influences everything. It shapes how decisions are made, team engagement levels, the capacity for innovation, brand perception, and even risk tolerance. 

When it is clear and embodied, culture becomes a powerful driver of coherence and performance. When it is fuzzy or misaligned, organisations don't just lose the trust of their teams. They lose their ability to move forward together.

True culture reveals itself in daily behaviour.

Many companies display their values: on the walls, on their careers site, in internal presentations. But an organisation's culture is never read in a list of words; it's revealed in what happens day-to-day.

Culture emerges most evidently in ordinary moments: when the team navigates an error, when leaders explain a difficult decision, when pressure mounts and managers must mediate, or when it’s time to recognise a contribution.

Teams are constantly observing the signals sent by leaders.

An organisation's culture therefore very concretely corresponds to the behaviours you encourage... and those you tolerate.

If a company claims to value collaboration but essentially rewards individual performance, the real culture becomes competitive. If it speaks of innovation but punishes mistakes, teams quickly learn to avoid risk.

It is the behaviour of leaders that truly defines culture. 

So a question for you; what behaviours are actually rewarded in your organisation? Do you “walk the talk”?

Psychological Safety: The Invisible Foundation

A healthy culture rests on a key element: psychological safety.

Simon Sinek talks about Circle of Security.

In a team where psychological safety exists, employees know they can ask a question, share an idea, be listened to, make a mistake, or ask for help – without fearing humiliation or sanction.

When this space exists, collaboration, innovation, and engagement increase naturally.

Looking back: not having had a psychologically safe environment for 8 years has had an impact on my energy, my mindset within the team and my career progression.

To live by values 

A list of vague values does not change any behaviour.

Integrity. Respect. Excellence. Innovation.

Inspiring words... but rarely actionable.

In my inspirational reading sources, Gustavo Razzetti offers a more concrete approach: translate values into observable behaviours..

For example: instead of saying: «We value respect»

Say

• «We challenge ideas, never people.»
• «Errors are shared to learn.»
• «Decisions are explained, even when they are difficult.»

Culture then becomes visible and practicable.

Harvard Business Review shares one very simple tip for testing an organisation's culture.

Once a month: invite an intermediate manager to observe a board meeting quietly.

After the meeting, ask a single question: what seemed aligned with our culture - and what wasn't?Teams don't expect perfect leaders. They expect coherence, especially when it costs something: time, power, speed.

Culture is built every day

It is shaped in very concrete moments: a recruitment, a promotion, a difficult decision, the way an error is handled.

Every decision sends a signal. And these signals build the invisible legacy of the organisation.

How to get started practically: three first actions for leaders

To start simply:

1. Observe the behaviours that are actually rewarded
Who receives recognition in your organisation? Why?

2. Translate a value into visible behaviours
Choose a core value and define three specific associated behaviours.

3. Creating more psychological safety in meetings
Start by asking a simple question: who sees things differently?

This type of micro-practice quickly transforms team dynamics.

What if culture became your leadership lever?

Culture, a powerful strategic lever for:

• strengthen engagement
• develop responsible teams
• To create sustainable performance

I help organisations translate their culture into concrete behaviours, team rituals, and managerial practices that really work in day-to-day life.
