In this paper we outline an approach to coupling measurement based upon program slicing. We claim that our coupling metric produces more precise measurements than related information-flowbased metrics. A prototype tool has been implemented to calculate these metrics. The next step is to evaluate the coupling (and related cohesion) metrics with respect to some hypotheses relating to the predication systems in which we claim they may be embedded. 1 Background After initial interest in code-level metrics in the 70s and early 80s the focus of software measurement moved `upstream' to the earlier stages of the product development life cycle. However, the definition and evaluation of code-level metrics has received renewed attention with the rise in popularity of the objectoriented paradigm [2, 3, 11]. This paper is concerned with code-level, slice-based metrics for assessing the level of information flow between functions and their coupling through this information flow. Our approach is an ..
