“…The recurring themes addressed in the mainstream literature within the IMSs scientific domain reported the limitations of the lack of integration (Almeida et al , 2014; Domingues et al , 2012, 2015), enabled the identification of critical success factors (Almeida et al , 2014; Oliveira, 2013) and dissected the guidelines and strategies for integration of MSs (Oliveira, 2013; Rebelo et al , 2014a). In addition, several authors proposed some contributions on the proper design of IMSs (Garengo and Biazzo, 2013; Manzanera et al , 2014; Rebelo et al , 2014b; Zeng et al , 2007), on the factors that impact the integration level attained (Bernardo et al , 2011, 2012) and suggested integration levels or degrees (Bernardo et al , 2009; J酶rgensen et al , 2006; J酶rgensen, 2008; Sampaio et al , 2012).…”
