For Pinto et al. (2009), competence infers in the quality of communication between the actors. Therefore, if the client identifies an unnecessary work carried out by the supplier, this will affect in greater intensity the competence trust, as the same authors justifies. Strahorn et al. (2015)also argue that, within a project environment, the adoption of a focused approach to selecting business partners should be considered based on trustworthiness rather than selection only due to the least cost,which covers the importance of competence trust.
