Abstact: This paper proposes a possible role for software metrics in the context of fault tolernt software development. In particular, interest is focused on those metrics which can be collected during the specification phase of the software project. These metrics can be used to identify several problems before product completio. The paper first introduces three groups of metrics found in the literature and then discusses their applicability as a management tool during the development of diverse software. Finally, an example is given of how specification metrics can provide estimates of parameters of reliability models. Though the described technique is not fully satisfactory, it can be used, in the absence of more sophisticated ones, to obtain reliability predictions from the models.
