Why now?
Tomorrow’s big challenges will depend on our ability to cooperate.
Cooperating and supporting others does not come naturally: it is a skill that can be trained and keeps improving. Knowing yourself better builds self-confidence, and that confidence paves the way to mutual trust.
With AI arriving in companies and organisations, jobs are changing fast. The more machines take over, the more what makes the difference becomes human: knowing yourself, understanding others without judging them, building together. This is how people and teams create value that technology alone cannot produce.
01 · SELF
Know yourself better
My behavioural preferences, my strengths, what gives me energy.
03 · TOGETHER
Cooperate better
Adjust the group’s self-image, understand each other better to balance strengths and tensions.
AND THEN
More efficient, everyone wins
A more efficient organisation, and a gain for everyone: the person, the team, the company.
01
Know yourself better.
Knowing your behavioural preferences, your strengths and what gives you energy means discovering where you contribute best. Because what we need is not to avoid all tension, but to feel called to achieve something. It is the starting point of every calm working relationship.
How it works
80 questions, a clear and easy-to-read report.
Leonardo3.4.5 measures four psychological dimensions and your attitude towards five strategic polarities of the organisation. Your report reveals:
- your 3 behavioural preferences on a grid of 8 functions
- the complete hierarchy of your behavioural preferences
- your behavioural preferences on 4 axes: interpersonal relations, information processing, decision-making, work organisation
- your attitude towards the five strategic polarities
Neither a skills test nor a judgement: your profile highlights your behavioural preferences in the context of your professional activities.

02
Understand others better.
Accepting that others perceive, decide and organise themselves differently. Differences stop being irritants and become resources, all the more valuable when teams face new challenges.
Four ways of being different
Neither side is better than the other. Knowing where everyone stands helps you adjust how you communicate, decide and organise together.

Ready for a little test?
Four questions for a first glimpse, and two more sets if you want to refine it. A wink, not a profile: the real questionnaire has 80 questions.
(These questions and their answers are purely indicative. They show a tendency, but do not reflect the richness of a Leonardo3.4.5 profile.)
Your snapshot
(Purely indicative snapshot, not a profile.)
This mini-test is experiential. The Leonardo3.4.5 profile means 80 questions and a full report: your 3 behavioural preferences on a grid of 8 functions, your strengths, what gives you energy and practical ideas for cooperating better.
03
Cooperate better.
Understanding each other better, trusting yourself and others, and developing cooperation, even between very different behavioural profiles. Bringing the team to life is at the heart of tomorrow’s big challenges, and no AI will ever replace this skill.
