Quantum decoherence gives the appearance of wave function collapse ( the reduction of the physical possibilities into a single possibility as seen by an observer ) and justifies the framework and intuition of classical physics as an acceptable approximation: decoherence is the mechanism by which the classical limit emerges out of a quantum starting point and it determines the location of the quantum-classical boundary.
