“…This has motivated many researchers to devise individual measures that are correlated to the effort required to maintain and adapt a piece of software (McCabe, 1976;Li and Henry, 1993;Chidamber and Kemerer, 1994;Henderson-Sellers, 1996;Briand et al, 1998;Sheldon et al, 2002;Martin, 2002;Bocco et al, 2005;Mouchawrab et al, 2005;Lanza and Marinescu, 2006;Lajios, 2009;Herraiz et al, 2009;Risi et al, 2013). Many of them have been validated in real-world projects (Lanza and Marinescu, 2006;Tempero et al, 2008;Balmas et al, 2009;Burger and Hummel, 2012;Mordal-Manet et al, 2013). Thus, these measures can be effectively used in practice to analyse the maintainability and adaptability of integration frameworks.…”
