The BUD System from Performance Assurance Systems enables video conferencing for classified spaces in pharmacy. Its two-way communication is always on between classified spaces as well as from classified spaces to non-classified spaces to help save time, reduce waste, and enable real-time communication. Because people are the biggest source of contamination, reducing the intrusiveness of cleanroom communications can thereby reduce the potential for contamination and better manage workflow. With this system, there is no need to schedule meetings or send invitations. It allows users to see who is available and start a conversation between one or more stations. Staff can be given direct feedback and instructions, allowing the pharmacy team to prioritize work on the fly and provide corrections in real time.
