What is 4D Lean?

4D Lean is a visual model, a language and a philosophy. This 4D Lean model is based on 20 years of experience. It is not a theoretical model, it is based on facts and figures, showing that happiness leads to better results and better results to happiness!

The X-axis shows the HOW, the 5 dimensions. It is a timeline and a visualization of maturity.

The Y-axis shows the WHAT with indicators as results, drive, mental health, profit, involvement, attitude, safety, sales, satisfaction, connection, innovation, consciousness, presenteeism, balance, happiness, … wholeness.

For the WHY: see mission below.

The happier, the more passionate and connected people are, the more productive they are.


Our mission is to help people find happiness.
It is our goal to create awareness by using the 4D model and a universal, simple language. Realizing goals, success, and self-actualization are the highest satisfiers. It makes people feel good.

Therefore it is essential to permanently have and achieve goals while in the right work environment.
° We guide you to structure and realize goals and dreams
° We help you to choose or create the right environment and make work awesome

We want to convince 0D and 1D companies that moving to 2-3-4D is a far more social sustainable and profitable way of doing business.
° We help people and companies finding their “ideal mix” based on their maturity
° We help them grow and reach the next level
