Real time wifi cellphone notification.  The fully baked applications I
am aware of that "might" are subscription based and go through a remote
server.  Usually via the cellular data network.  Even if everything is
tits and the cellular data network is relatively idle there will still
be a lag.  It would have to be local to have any chance of approaching
real time.  This may mean hiring a coder to write the cell phone ap and
figuring out how to bypass the ApStore/PlayStore to load it on the
phones.  You would probably also need a program running on an individual
PC (could be a micro with embedded OS) to manage the data.

Here is the real problem.  The employees themselves will ignore the
notifications knowing other people are also getting the notifications.
"I was busy, didn't feel like it, and management is evil for pushing
this on us."  Well, if they are commission based sales people you might
get the opposite problem.  A gang of fanged carnivorous starving
seagulls descending on an unsuspecting victim.    "MINE!  MINE!  MINE!"

I have done something to similar to this in a hardwired non cell based
application.  I drew floor plan of a building, laminated it on a board
covered with polycarbonate, installed a programmable relay board in an
alarm panel, wired the relays to light LEDs cut into the floor plan.
Then I set all the keypads in the building to chime.

A similar mass produced product is a waitress call system.  I've never
installed one, but I have repaired a couple.  Wait staff are motivated
to look at the light board, because generally better service equals
better tips.

Upon second thought, there are a number of wifi trigger devices on the
market that send data to a remote location.  You might be able to adapt
something that is off the shelf.  IT "professionals" are always trying
to monitor IT hardware remotely.  Power, data, heat, battery alarm,
etc...  If you can send texts (most cell services have an email to text
format) from a PC it could all be done without an ap, but then you are
dependent on the cellular network again. You still need some kind of
controller to monitor the input and managed the output.  Scripting under
Windows might be possible.  Never really looked at that.  Local wifi
direct would be better.
