Suppose I have a coordinator which manages and supervises several devices. In fact these devices are under the supervision of this coordinator. We want to mention these devices.
What is the best phrase for referring to these devices? Is it correct to say:
coordinator's under supervision devices
If you use the wording you have, it would make the meaning clearer if you used hyphenation:
coordinator's under-supervision devices
This makes it obvious that under-supervision is being used adjectivally to modify devices.
However, you could also keep those exact words, but reorder them:
devices under coordinator's supervision
Also note that you'll probably want to use an article or demonstrative in front of coordinator: (a / the / this / that) coordinator's.
In this case, "under supervision" can be simplified to be simply supervised. So, you could refer to them as:
the coordinator's supervised devices
Or, if it's obvious that you're talking about the devices supervised by that coordinator, you can leave out the posessive (making a much simpler phrase):
the supervised devices
