The leisure industry is influenced by what happens in society. This impact may take a while, such as the gradual ageing of the western population. Such gradually (sometimes even imperceptibly) increasing forces are also called stress factors.

These are referred to as shock factors or black swans or, in severe cases, disruptions. As a company or an organisation, you can try to guard against the effects of future influences in advance, by spotting them early and taking measures which reduce vulnerability to such developments. If you can manage that, you become more ‘future-proof’.
