The idea of the special issue was conceived in 2012 when the editor-in-chief, Dr Luiz Moutinho invited me to serve the Journal of Modelling in Management (JM2) in the role of a Guest Editor for a special issue. What ensued was a call for papers in May 2012 and an intense activity of submissions, reviews and revisions. In about two years, the special issue was completed with acceptance of four excellent manuscripts. The same are discussed briefly in this editorial.
