For me it is always inspiring to see how our efforts to arrive at good and useful solutions for our clients not only leads us to better decisions, but also to more insight into coherence and a sense of community (it is ‘our’ model!). This sense of community often turns out to be a spin-off that is not foreseen in advance, but much appreciated in hindsight. So yes… mathematics is very important, but let’s not forget what it does to the people involved.
From my business economics education (MSc) combined with a technical background (BSc Electro), I am quite analytically oriented. The beauty of developing models (also in cooperation with Copernicos), is that we often connect many different domains of interest. My various educational backgrounds support this. So… technique: yes and finance : where possible. But let’s not forget the connection with people, with their ambitions, their knowledge and their experiences.
Lately, we have also learned that communication about what we have done (and how we did it), is at least as important as the content of the solution. Every time we try to find a form that works best for the customer.
