Hospitals are increasingly joining forces in networks of different types, sometimes with other healthcare players. This is an unmistakable trend, but forming networks is also an important strategic decision. How can hospitals ensure the right decisions are taken, both today and tomorrow, guaranteeing a robust, resilient and versatile organisation in the long run? Changes are rapidly succeeding one another, but who knows what healthcare will be like fifteen years from now and what the best set-up would be for these networks? No one can predict the future. However, despite all the uncertainties, a scenario analysis can help in the decision-making process.
