Stijn van Diemen
Strategy
About
For me, developing strategy is a co-creative act. You will tell me about your situation, your dreams, your possibilities and your insights. I will challenge you, inspire you, make you think differently; but also guide you, support you and protect your interests. My experience and expertise, my knowledge of models and processes will make room for our joint creativity. Together, we will create a vision of your future and design the pathway to make that vision come true.
Approach
01. Co-Explore
We will explore relevant developments in your environment, discover your competences and define your challenge.
02. Co-Create
We will use models, examples, creativity and innovative processes, work in large or small groups or one on one and create a vision on your future.
03. Co-Activate
We will discover what’s there to use and add what’s missing, define conduct principles, create the necessary bodies and means and draw a timeline.
04. Co-Develop
We will start using what we found and created. We will monitor your progress. We will stay together as long as we both think necessary.
Clients
Alrijne — Yvonne Wilders, former Chair of the Board of Directors
“Stijn van Diemen helped us recalibrate and standardise our brand. What we were looking for was an anchor of who we are in a constantly changing context; something to keep us flexible and robust at the same time.
It is impressive how Stijn got to the essence in a short time. He formulated workable frameworks, not only for everyone building our brand now, but also taking into account developments in the future. With the brand policy and renewed visual identity developed by Stijn, we are confidently building on Alrijne’s ‘strong brand’ in the region. The extensive knowledge and experience that Stijn brings has proved to be of great value.”

Auto Recycling Nederland — Paul Dietz, director
“Stijn has helped Auto Recycling Netherlands on several occasions. In 2023, this led to a new strategy. In several sessions, we went from many ideas and documents to a structured document, with Stijn keeping tight records, on process but also on content. Part of the process was also a broad meeting with employees. His way of working suits ARN well, I would definitely recommend him for that.”
