functional
Does its job
Functional means working or operative—a functional appliance does what it's supposed to do.
It can also mean practical rather than decorative: functional design prioritizes utility over aesthetics.
In specialized contexts, functional describes things organized around purpose or function: functional programming, functional medicine.
Someone described as functional is managing adequately despite difficulties: She's barely functional before her morning coffee.
