An event is full of uncertainties like power failure, equipment failure, medical emergency, brawl, stampede, fire, sponsorship withdrawal, last minute turned down by an artist etc. How will you deal with all these contingencies without a well thought out risk management plan.
Risk management is done at each and every stage of event production. For e.g. when risk management is done in the information management field, then it deals with loss of data due to data theft or hard disk crash. When risk management is done in the security management field, then it deals with brawl, stampede, medical emergency, accidental fire etc.
Similarly there are risks associated with: human resource, finance, marketing, quality management, attendees, food and beverages management, programs, technical management, infrastructure, logistic, procurement and team management.
