As I see it, facility management in the context of a workplace concerns itself with creating, operating and maintaining commercial environments and infrastructure. In an office context I believe the term "building management" is largely synonymous.
So are questions about this topic considered suitable for the Workplace?
This question was prompted by this question asking for ways to prevent conference phones from migrating through the office.
We've previously had a thread on ergonomics-related questions with a clear consensus that the community believes this is on topic. But while that's also a topic that doesn't deal with interpersonal relationships it's a very different and better scoped subject. In my view the answers given there also wouldn't apply to facility management.
Note: I consider this to be entirely distinct from office management which has a much more obvious focus on business processes and people.
