“…Some studies with metrics and measurement frameworks for object-oriented systems have been presented in Laranjeira (1990), Meyer (1990), Henderson-Sellers (1991, 1993, Coulange and Roan (1993), Li and Henry (1993), BritoeAbreu et al (1995), Nesi and Campanai (1996), Bucci et al (1998), Fioravanti et al (1998a,b), Nesi and Querci (1998), and Zuse (1994), where general concepts for the estimation of system size, complexity, and reuse level have been proposed together with many other metrics. Unfortunately, the eort for de®ning new metrics has not been supported by the implementation of assessment tools and methodologies.…”
