A predicting variable would have to explain at least 10% (0.1)
of the variance of the variable that it predicts (Roldán and
Sánchez-Franco, 2012). Chin (1998) considers R2 values of 0.67,
0.33, and 0.19 as substantial, moderate, and weak, respectively.
In our case, all the relationships set out in the structural model
fulfil this rule. The influence exerted by the process methodology
variable on the rest of the variables is emphasised when
explaining the more than 20% of the explained variance of the
knowledge variable and more than 67% of the suppliers/partners
variable. It is also worth emphasising the importance of the
