An important measure for triggering a contingency plan is specific defined measures, such as weather conditions. Contingency plans are developed to address unexpected situations that can disrupt event planning or execution. Having specific criteria, such as adverse weather conditions, allows event planners to know precisely when to activate their contingency plans.

For instance, if a severe weather alert is issued, the planner can implement a pre-established contingency plan, which may include moving an outdoor event indoors or adjusting schedules accordingly. This proactive approach helps ensure the safety of participants and the overall success of the event.

The other options might be relevant in the planning process, but they do not directly represent the unexpected external factors that often necessitate a contingency plan. For example, the number of attendees enrolled might impact logistics but is typically a known quantity well before the event occurs. Similarly, securing sponsors and the availability of keynote speakers are important for planning but do not inherently trigger a contingency response as specific defined measures do.
