Ceremonies invite a specific audience, usually internal, to attend a formal event. Awards ceremonies, in which employees are rewarded for their outstanding work throughout the year or the quarter, or retirement ceremonies provide common examples of a ceremony for your business.
Ceremonies can boost company morale and highlight individual accomplishments within your organization. By giving awards and noting specific achievements, ceremonies can also attract media attention and provide press opportunities for your brand.
