our story

The cogNIAM® method and the results of accessible, manageable and productive knowledge are naturally important for our company. We work with these every day and time after time we provide irrefutable proof that our method works and provides companies with unparalleled added value. But even more than ‘how’ and ‘what’, it is 'why' we do this that is important for us.


The scientific basis

For more than 45 years, our founder Professor Sjir Nijssen has been devoting his efforts to teaching people how to handle knowledge more efficiently. In the 1970s, he discovered how you can identify, analyze and structure knowledge in such a way that you can use it in calculation. This enables specific knowledge to be made accessible to a larger group of people in understandable language, preventing wastage and allowing companies to prosper.

His insight was the main driving force behind developing the present cogNIAM® method – a scientific method that is central to PNA’s approach. It is a method that enables organizations to handle knowledge sustainably on the basis of current world standards in the field of knowledge management.

“You can identify and structure knowledge in such a way that you can use it as a basis for calculation, and in a way that will save you time and money immediately and in the long term in particular. This is what sets PNA apart.” – Emer. Prof. Sjir Nijssen

No frivolous theories

Our work is motivated by an idealistic vision – the idea that an exact approach to knowledge, the wastage of knowledge, time and money can be prevented worldwide. You could call us idealists; you could call us do-gooders, but we believe in what we do. And we’ve been proving that for a long time.

Space to innovate

With the appointment of Sjir’s son Maurice Nijssen as managing director, PNA has undergone a further significant development. Maurice is constantly occupied with making the knowledge capital of organizations more broadly applicable.

This extends from the business operations of organizations to cooperation in the chain – not just for commercial parties but also to develop innovative solutions for social issues on the basis of partnerships. So we think out of the box. We don’t get bogged down in frivolous theories but create on the basis of a through, fundamental grip on knowledge capital and thus on opportunities for growth.


“Science is a beautiful discipline. It questions accepted opinions. And that is also a fundamental principle to which we attach great value at PNA. But it shouldn’t stop at science – it should go further. It must be applicable from a commercial viewpoint. These are not conflicting interests, and certainly not if you can give organizations a better grip on their knowledge capital. And if they can implement changes quicker, this will give them more space for creating innovations.” – Maurice Nijssen MSc
