By definition, a digital twin is the “electronic image or mirror of a real or virtual object, e. g. a product or a logical organization”. This mirror image of an organization is useful for visibility and control, the feasible simulations, however, enable better planning und prediction. In fact, digital twin can be used for predictive maintenance, e. g. of trains or planes, and for security aspects. The digital twin of an organization (DTO) is already feasible by using an appropriate SaaS solution that builds a mirror image of an enterprise etc., establishes all processes and communication lines. It enables the management to simulate the benefits and risks of changes to the original, e. g. by creating a new business model.
