SLAs fail in the gaps you can't see
A support floor of hundreds of seats across shifts and sites generates a simple, brutal question every hour: is the coverage we promised actually at its desks and working? Supervisors walk rows or ping team leads; adherence gets measured after the fact from ticket systems; and when a client asks for proof of the staffing they pay for, operations assembles it by hand. At BPO scale, invisible idle time and quiet no-shows are the difference between margin and penalty.
