As Roldán and Sánchez-Franco (2012) describe, the PLS
methodology starts from the graphical description of the
structural or internal model, that is, from a representation by
means of symbols of the relationships existing between the
latent variables (constructs), and of the relationships existing
between the indicators and the constructs of the measurement
or external model (Fig. 5). The latent variables are represented
by means of circles, being able to distinguish between
independent (exogenous constructs) and dependent variables
(endogenous constructs). In this particular case, the independent
variable would be the process methodology construct, the
rest being endogenous constructs. The arrows and their
direction indicate the predictive relationships between the
