Limitations and future research lines
The interpretation of the results and conclusions of this study
are subject to a series of limitations, principally of a methodological
character. The first limitation is due to the technique used
for the proposed model: structural equation modelling, which
assumes the linearity of relationships between the latent
variables. The second is related to the notion of causality. Our
study has considered a soft modelling approach oriented more
towards prediction than causality. Thirdly, the design of the
research is cross-sectional instead of longitudinal. Objectively,
the improvement and learning processes need time to produce
more significant effects, so that their effectiveness can be
evaluated more exactly. Finally, the conclusions reached cannot
be completely generalised as they have been formed from a study
pertaining to a geographic context and a specific business
management style.
