There are various flavors of UNIX systems. System V refers to flavors
derived from the last AT&T version. As opposed to those derived from BSD.

POSIX is a set of standards that were created to promote portability
across the various flavors of UNIX by defining a common set of
interfaces, for example.

The point being that if you want to build a software system that will
run on as many UNIX platforms as possible you can build it within the
bounds of what POSIX specifies and reduce your costs. The amount of
code specific to any given platform decreases dramatically.
