Operators (fund managers and traders) are regularly involved in fraudulent operations. Their cost amounted to over $40 billion in the last decade. We think that one of the main reasons is related to the nature of interrelations between risk-controllers and operators. Controllers are often too poorly skilled and operators consider themselves as superior human beings and are therefore reluctant to explain themselves. Existing structures encourage this. That is why we propose an approach based on the concept of enactment, which will entail a morphogenesis of structures. This will help operators realize that they are just ordinary people, which will then help them suffer less from their working life. As a result, they will develop careful interrelations, resulting in a lesser risk of fraud. We also provide a tool to measure the quality of these enactments and to perform them: the appropriation scales. Realizing that they are not asked to do extraordinary things, operators will less suffer psychologically and be less tempted to fraud to escape this pain.
