working model
Operational test version
A working model is a functional version of something—a prototype or demonstration piece that operates as intended, though often simplified or scaled down.
An engineer builds a working model to test a design before full production.
The phrase extends to conceptual frameworks: We need a working model of how customers make decisions.
The emphasis is on functionality over polish.
