Modelling operational decisions and managing them gives complete control over business rules. Appreciating the power of this technique, Marwim started specialising in decision modelling and management. He is a DMN trainer at Le Blanc Academy, where he teaches the decision modelling training course authored by James Taylor. Marwim combines his DMN expertise with his acumen in Business Architecture. He is one of the trainers of this BCS course at Le Blanc Academy.

For the last 5 years, Marwim has focussed on applying decision modelling and management insights within the public sector in The Netherlands, where its added value is slowly being discovered. He is the chairman of the Business Rules Platform Nederland, which has a large audience from Dutch Government Agencies. He also chaired the DMN On-Ramp review committee, which helped spread the many advantages of decision modelling and management. Along with James Taylor, he annually shares his decision modelling experience with students following the Business Decision Management course at the University of Lund.

Why DMN?

• We need good stories about the key role of (operational) business decisions.
• Let’s start by admitting that we know so little about decision-making. Why do we always look to the outcome of a decision?
• I see an analogy between outcome fixation and a general tendency to avoid risks instead of taking well-managed risks. This arises because we are not sufficiently in control of our decision-making. A better understanding of decision-making allows us to take more well-managed risks. In part because it empowers us to explain fully why we want to take that risk.
• Being able to explain a decision means being able to learn from the effects of that decision and adjusting it to individual situations.
• We live in an economy that constantly needs the highest possible level of predictability. Why? I believe that the more we understand decision-making, the more complexity we can manage effectively.

DMN will help us to achieve these goals.
