(OS1) is a comprehensive, high performance management system for cleaning organizations. (OS1) is based on Team Cleaning. It employs in-depth training, from the upper-management down to the cleaning worker level. (OS1) prescribes standardized cleaning tools and procedures. This system is work-loaded into cleaning teams. Each cleaning worker is trained and certified on specialized tasks. Workers are ‘kitted’ with specific tools and chemicals for each team job function, which have been benchmarked as the best practice by the (OS1) Users. This simplification of the cleaning process results in a safer, cleaner, healthier and happier working environment.
