Who has the responsibility to decide that the impact of local events is systematically a sub-part of the destination validation? This classification is not a universal truth and requires a clear governance for its application.
The decision process must establish when local events become a critical variable, for example, when they directly affect logistics or the planned budget.
A business trip to Frankfurt during the Book Fair, for instance, radically changes hotel availability and prices, requiring an escalation for a special approval.
Without clear ownership of this decision and documented criteria, there is a risk of ad hoc execution that can lead to costly surprises.
