For a finite group $G$, we will introduce an obstruction theory for constructing $G$-equivariant fibrations. Equivariant fibrations play an important role in the construction of free group actions on finite $CW$-complexes which are homotopy equivalent to products of spheres. We also give a survey on finite group actions on products of spheres and explain how equivariant fibrations can be used to construct such actions.
