Formerly known as the (OS1) Users Symposium, this is an annual gathering of (OS1) end-users, members of the Cleaning Alliance, and other cleaning industry representatives invited by the Simon Institute. They share this unique opportunity to benchmark industry best practices and discuss the successes and challenges of implementing a standardized management system into their cleaning organizations. Cleaning professionals who use (OS1) and professionals who are just interested in learning more are all encouraged to attend this event.
