  In this paper, we look into what happens to a quantum system under repeated
measurements if system evolution is removed before each measurement is
performed. Beginning with investigating a single two-level system coupled to
two independent baths of harmonic oscillators, we move to replacing it with a
large collection of such systems, thereby invoking the large spin-boson model.
Whereas each of our two-level systems interacts strongly with one of the
aforementioned baths, it interacts weakly with the other. A polaron
transformation is used to make it possible for the problem in the strong
coupling regime to be treated with perturbation theory. We find that the case
involving a single two-level system exhibits qualitative and quantitative
differences from the case involving a collection of them; however, the general
effects of strong and weak couplings turn out to be the same as those in the
presence of system evolution, something which allows us to establish that
system evolution has no practical bearing on any of these effects.
