SiD Integrated Sustainability Training | 24, 25 August and 01 September

News > 3 day Symbiosis in Development (SiD) certification course

We are proud to present our renewed Integrated Sustainability: Symbiosis in Development (SiD) Training hosted by Tom Bosschaert, Founder of Except and developer of the SiD framework.

Join an intimate group of professionals in a  2+1-day training to deepen your knowledge and understanding of sustainability. Symbiosis in Development is a framework that focusses on the question: what is sustainability really? SiD unravels the complexity of sustainability and makes both its long term abstract qualities as well as its down-to-earth physical properties clear. In this workshop, you get hands-on with SiD, and learn how to apply its principles in real world cases of analysis, strategy, concept development and reporting.  Participants receive an official SiD certificate upon completion.

 Integrated Sustainability Training

The world is changing, but what about you? You're scanning the horizon looking for smart ways to progress and flourish. But what is the right direction, which solutions work and which are dead ends? How do you combine quick wins with necessary long term investments? 

We believe that many answers lie in sustainability. Not the “sustainability” of power saving light bulbs or recycled toilet paper, but real integrated sustainable innovation. What it is and why it leads to prolonged success is what you will discover in this  training. We work on real-world cases, discuss, co-create and explore all aspects surrounding sustainability, including circularity, ethics, systems thinking, and resilience.

"Frustrated by the complexity of sustainable development? Join the Integrated Sustainability training! Please take my recommendation for the best systems thinking and systems change method I have learnt. Except's thinking prepares you for the next century."

Bas Mentink, Consultant Circular Economy at Royal HaskoningDHV



Learn to tackle sustainability challenges on a system-level

In development for two decades, Symbiosis in Development has been succesfully applied to over 500 projects in contexts as diverse as urban renewal, policy making, design, business strategy, healthcare, and industrial innovation.   SiD  enables different  disciplines to  work together and evaluate sustainability spectrum-wide. It uses systems thinking, systems mapping, design-thinking, and complexity thinking in a co-creation process.  By using a team-based approach it helps to structure and steer group processes from beginning to end,  and supports collective understanding. This, in turn, supports the team;'s ability to both follow a long term vision, and apply immediate, concrete day to day action.

Co-creation training

The training offers a basic introduction of SiD and practical group work using  a case study. We mix  presentations,  games, and videos in  an  informal  environment.  A team of max 12 people from different professional backgrounds join and form co-creation teams.  The teams are lead by trainer Tom Bosschaert, main developer of the SiD framework.


Participants receive an offical SiD basic training certificate upon full completion of the course. This enters participants in the SiD certification database which is currently under development, and will be published at the SiD website www.thinksid.org.
