There are 1,500 doors to be installed in Tom's program. Each of the 1,500 doors is required by the building code to swing into the room rather than swing out into the hallways. It has come to Tom's attention that part of the team installing the doors has installed nearly 200 doors to swing into the hallway rather than into the rooms. Tom instructs the team to fix the problem. What type of action has Tom taken in this instance?
